NEW QUESTION # 10
An administrator is monitoringthird-party WLAN transmitters m HPE Aruba Networking Central and some of them are classified as rogue and suspected rogue How aresuspected rogues classified when using the default classification method for the rule "Suspected AP On-Prem" in HPE Aruba Networking Central?

A. signal level ="-50 dbM" AND WLAN classification = "Interfering"
B. signal level = "-50 dbM" ANDWLAN classification = "On Wire"
C. signal level = "-55 dbM" AND WLAN classification =''Interfering"
D. signal level = '-65 dbM- AND WLAN classification ="On-Prem"

Answer: D

Explanation:
The question asks how suspected rogue APs are classified using the default classification method for the
"Suspected AP On-Prem" rule in HPE Aruba Networking Central.
* Analysis of Options:
* Option A:Correct. Suspected rogues are classified with a signal level of -65 dBm (indicating proximity) and WLAN classification of "On-Prem" (indicating they are on the premises).
* Option B:Incorrect. A signal level of -55 dBm is too strong, and "Interfering" is not specific to on-premises rogues.
* Option C:Incorrect. A signal level of -50 dBm is even stronger, and "Interfering" is incorrect.
* Option D:Incorrect. "On Wire" classification applies to wired rogue detection, not wireless on- premises APs.
* Why Option A is Correct:In HPE Aruba Networking Central, the "Suspected AP On-Prem" rule identifies rogue APs based on their signal strength and location. A signal level of -65 dBm indicates the AP is close enough to be on the premises, and the "On-Prem" classification confirms it's detected within the managed network's environment. This default rule helps identify potential security threats by flagging unauthorized APs with moderate to strong signals, distinguishing them from interfering or distant APs, as per Aruba's wireless security framework.
* Relevance to Certification Objectives:
* WLAN (9%):Designing and troubleshooting RF attributes and wireless security functions.
* Security (10%):Troubleshooting and identifying rogue APs in customer networks.
* Troubleshooting (10%):Analyzing wireless issues using Aruba Central tools.

NEW QUESTION # 11
A customer wants to deploy loT security devices that are PoE-powered. Dueto its criticality. it is required that those devices remain active even during a switch software upgrade. What is a valid solution to meet customer requirements?

A. a VSX pairof switches for redundancy
B. power-over-ether net quick-poe
C. power-over-ethernet always-on
D. power-over-ethernel priority

Answer: C

Explanation:
The question involves a customer deploying PoE-powered IoT security devices (e.g., door locks) that must remain active during an AOS-CX switch software upgrade. The task is to identify a valid solution.
* Analysis of Options:
* Option A:Incorrect. A VSX pair provides redundancy but does not guarantee PoE continuity during a single switch's upgrade.
* Option B:Incorrect. quick-poe reduces PoE startup time but does not ensure power during upgrades.
* Option C:Correct. power-over-ethernet always-on ensures PoE remains active during software upgrades, meeting the requirement.
* Option D:Incorrect. PoE priority adjusts power allocation but does not guarantee continuity during upgrades.
* Why Option C is Correct:The power-over-ethernet always-on feature on AOS-CX switches ensures that PoE power delivery continues uninterrupted during software upgrades or reboots, critical for devices like IoT security door locks that require constant power. This feature prevents power cycling on PoE ports, maintaining device operation. For example, enabling it on relevant ports (e.g., interface 1/1/1 power-over-ethernet always-on) ensures compliance with the customer's requirement, as per HPE Aruba Networking's PoE high-availability guidelines.
* Relevance to Certification Objectives:
* Connectivity (9%):Configuring PoE for critical device deployment.
* Network Resiliency and Virtualization (8%):Ensuring device uptime during maintenance.
* Troubleshooting (10%):Resolving PoE continuity issues.

NEW QUESTION # 12
Exhibit.

After Implementing a distributed overlay with distributed anycast gateways, you noticed that toomany ARP packets are being replicated to every access (leaf) switch Which command can you use to optimize the network?

A. interface vlan 10 ip proxy-arp interface vlan 11 ip proxy-arp
B. evpn ip proxy-arp
C. evpn arp-suppression
D. vlan 10 arp-suppression vlan 11 arp-suppression

Answer: C

Explanation:
In an EVPN VXLAN distributed overlay network, excessive ARP packet replication (flooding) to all leaf switches is observed. We need the command to optimize this.
* EVPN ARP Optimization:EVPN uses its control plane (BGP) to distribute MAC and IP address reachability information. Leaf switches (VTEPs) learn these mappings. To reduce ARP flooding across the VXLAN fabric:
* ARP Suppression:VTEPs intercept ARP requests. If the VTEP already knows the MAC address for the requested IP (learned via EVPN), it can suppress the ARP request, preventing it from being flooded over VXLAN.
* Proxy ARP:VTEPs intercept ARP requests. If the VTEP knows the MAC for the requested IP, it can generate an ARP replyon behalfof the remote host.
* AOS-CX Commands:These features are configured within the EVPN context.
* evpn arp-suppression (B): Enables the ARP suppression feature for EVPN.
* evpn ip proxy-arp (C): Enables the proxy ARP feature for EVPN.
* Options A and D use standard interface/VLAN level arp-suppression or proxy-arp commands, which are not specific to optimizing flooding within the EVPN VXLAN fabric itself.
* Conclusion:To optimize by reducing the replication/flooding of ARP packets across the EVPN VXLAN overlay, enabling evpn arp-suppression (Option B) is the direct command. This leverages the EVPN control plane knowledge to stop unnecessary ARP flooding.

NEW QUESTION # 13
You haverecently configured a switch for 802.IX authentication with HPE Aruba Networking ClearPass. A security admin is seeing events withthe following description in ClearPass Event Viewer.
RADIUS authentication attempt from unknown NAD (10.10.1.10:1812)'
Which command should you us to identify theconfiguration issue?

A. show radius-server detail
B. show ip source-interfaceradius
C. show radius-server shared-secret
D. show aaa authentication-server radius

Answer: B

Explanation:
The ClearPass Event Viewer message "RADIUS authentication attempt from unknown NAD (10.10.1.10:
1812)" indicates that ClearPass received a RADIUS request from the IP address 10.10.1.10, but this IP is not configured as a trusted Network Access Device (NAD) in ClearPass's network device list, or the shared secret doesn't match. The first step in troubleshooting on the switch side is to verify which source IP address the switch is actually using to send these RADIUS requests.
* RADIUS Source IP:AOS-CX switches can be configured to use a specific source IP address for RADIUS packets, often using the ip source-interface radius [vrf <vrf-name>] command. This is important if the switch has multiple IP interfaces or uses VRFs.
* Analysis of Commands:
* A. show ip source-interface radius: This command directly displays the configured source interface and IP address used for RADIUS communications, allowing comparison with the IP configured in ClearPass.
* B. show aaa authentication-server radius: Shows server group configuration, not the source IP used by the switch.
* C. show radius-server shared-secret: Not a standard command; secrets are usually masked in other commands.
* D. show radius-server detail: Shows configured RADIUS server details but doesn't explicitly show the source IP the switch is using to originate packets.
* Conclusion:To identify why ClearPass sees requests from an "unknown NAD" IP (10.10.1.10), the first step on the switch is to confirm which source IP it's using. show ip source-interface radius provides this crucial information.

NEW QUESTION # 14
A senior engineer from the network operations team has reported an intermittent problem where some PoE- powered devices are randomly losing power. During your investigation, you found that port 1 of the Acc-1 switch is currently presenting the behavior shown in the CLI output for the Acc-1.

What is a probablecausa lot poor 1/1/1 is denying PoE?

A. PoE port priority sot to low
B. switch PoE powerbudget exceeded
C. PoE was manually disabled for port 1/1/1.
D. This switch does no! support PoE class 4.

Answer: B

Explanation:
The question involves intermittent PoE-powered device power loss on port 1/1/1 of an AOS-CX switch (Acc-
1), with CLI output (not provided) indicating a PoE issue. The task is to identify a probable cause.
* Analysis of Options:
* Option A:Incorrect. AOS-CX switches typically support PoE Class 4 (802.3at, 30W), sufficient for most devices.
* Option B:Correct. If the switch's PoE power budget is exceeded, it may deny power to port 1/1
/1, causing intermittent device failures.
* Option C:Incorrect. Low PoE port priority may deprioritize the port but is less likely to cause complete power loss compared to budget issues.
* Option D:Incorrect. Manual disabling of PoE would cause consistent power loss, not intermittent issues.
* Why Option B is Correct:AOS-CX switches have a finite PoE power budget (e.g., 370W or 740W, depending on the model and power supply). If the total power demand from connected devices exceeds this budget, the switch denies power to some ports, often intermittently as devices cycle or negotiate power. For port 1/1/1, this could manifest as random power loss for the connected device. The CLI output likely shows a "power denied" status (e.g., via show power-over-ethernet brief). Checking the PoE budget (show power-over-ethernet) and upgrading power supplies or prioritizing critical ports resolves the issue, aligning with HPE Aruba Networking's PoE troubleshooting guidelines.
* Relevance to Certification Objectives:
* Connectivity (9%):Troubleshooting PoE deployment issues.
* Troubleshooting (10%):Diagnosing power-related issues in campus networks.
* Switching (19%):Implementing PoE configurations for Layer 2 devices.

NEW QUESTION # 15
the administrator of a largo company noticed thatthere are some problems with UCC sessions on a wired network. Some employees complain about dropped calls and poor quality. The administrator wants to monitor, jitter on AOS-CX switches with iP SLA. but notices results spiking to 100% What should the administrator check first to correct monitoring to run as desired?

A. CoPP settings
B. memory and processor usage
C. number of NAE agents
D. source IP and source port combination

Answer: B

Explanation:
The administrator observes IP SLA jitter monitoring results spiking to 100% when monitoring UCC sessions.
This indicates either extremely severe network jitter or, more likely, a problem with the IP SLA operation or measurement itself on the AOS-CX switch.
* IP SLA & Jitter:IP SLA measures jitter by analyzing the inter-packet delay variation of probe packets.
Accurate measurements depend on the switch generating and processing these probes consistently.
* Factors Affecting IP SLA Accuracy:
* Switch Resource Contention:If the switch's CPU or memory is heavily utilized, the operating system might not schedule the IP SLA process promptly. This can lead to inconsistent generation or processing of probe packets, causing highly inaccurate measurements, including extreme jitter values like 100%.
* Control Plane Policing (CoPP):IP SLA packets are control plane traffic. If CoPP policies are too restrictive, they might drop or delay IP SLA probes, skewing results.
* Network Path Issues:Actual severe jitter on the network path would also cause high readings, but 100% spikes often suggest measurement error first.
* Troubleshooting Steps:When encountering unexpectedly high or erratic IP SLA results, the first step is often to rule out issues with the monitoring device itself.
* Analysis of Options:
* A. memory and processor usage: Checking the switch's resource utilization is crucial. High CPU
/memory load can directly impact the timing accuracy of IP SLA operations.
* B. source IP and source port combination: Unlikely to cause 100% jitter spikes unless fundamentally misconfigured causing probe failure.
* C. number of NAE agents: NAE agents consume resources, but checking overall CPU/memory (A) is more direct.
* D. CoPP settings: A valid concern, as CoPP affects control plane traffic. However, checking overall system load (A) is typically a primary check before delving into specific policies like CoPP.
* Conclusion:High memory and processor usage (Option A) on the switch running the IP SLA operation is a common cause for inaccurate timing and resulting erroneous jitter measurements. This should be checked first to ensure the monitoring platform itself is functioning correctly.

/Memory, CoPP). This relates to "Performance Optimization" (6%) and "Troubleshooting" (10%).

NEW QUESTION # 16
A customer hassot a requirement for VLAN 151 to be an isolated VLAN. A colleague has copied and pasted a partialconfiguration, but you do not achieve the desired outcome. This is the code that was added:
What should be added to the configuration before this code to achieve the desired result?

Answer: D

Explanation:
The customer requires VLAN 151 to be configured as an isolated Private VLAN. A partial configuration was added, but the desired outcome wasn't achieved. We need to determine which configuration snippet should be addedbeforethe (unspecified) partial configuration to correctly set up the Private VLAN structure.
* Private VLAN Configuration Fundamentals:
* APrimary VLANmust be defined. This VLAN carries traffic between promiscuous ports and ports in associated secondary VLANs.
* Secondary VLANs(either isolated or community) are associated with the primary VLAN.
* Ports are then mapped to either the primary VLAN (promiscuous ports, typically router/firewall connections) or a secondary VLAN (host ports). Isolated ports within thesameisolated VLAN cannot communicate with each other.
* Analyzing the Options (Assuming VLAN 15 is the intended Primary):
* A)
vlan 15
private-vlan primary
vsx-sync
This correctly defines VLAN 15 as the Primary Private VLAN. The vsx-sync command ensures this configuration is synchronized across a VSX pair (relevant if applicable). This is the necessary prerequisite before defining VLAN 151 as an isolated secondary VLAN and associating it with VLAN 15.
* B)isolated-vlan primary is incorrect syntax. The command is private-vlan primary.
* C)primary-vlan isolated 151 is incorrect syntax for defining either the primary or secondary VLAN type/association within the primary VLAN context.
* D)private-vlan isolated 151 within the vlan 15 context is incorrect syntax. The private-vlan isolated command belongs under the configuration of the secondary VLAN (VLAN 151 in this case).
* Conclusion:Before configuring VLAN 151 as private-vlan isolated and associating it, the primary VLAN must be defined. Option A correctly shows the command (private-vlan primary) under the intended primary VLAN's configuration (vlan 15) to establish it as the primary VLAN.

NEW QUESTION # 17
Match the BGP connection slates to the conditions thatcould have caused that state.

Answer:

Explanation:

Explanation:
The router is able to process update messages. -->established
The router is waiting for the neighbor's open message. -->open sent
Routers have agreed on matching feature sets. -->open confirm
The session establishment has timed out. -->idle
This question requires matching BGP connection states from the BGP Finite State Machine (FSM) to descriptions of conditions that occur within or lead to those states.
* Idle:This is the initial state where BGP awaits a start event or retries after a failure. It's also the state entered upon error detection or session closure, including timeouts during connection attempts.
* Matches:"The session establishment has timed out." - A timeout during the connection process forces the BGP process back to the Idle state to potentially retry later.
* OpenSent:After a TCP connection is established, the local router sends a BGP OPEN message with its parameters (AS number, capabilities, etc.) and transitions to the OpenSent state while waiting to receive an OPEN message from its BGP neighbor.
* Matches:"The router is waiting for the neighbor's open message."
* OpenConfirm:Once the router receives an OPEN message from its neighbor and validates the parameters (e.g., matching AS, compatible capabilities), it sends a KEEPALIVE message and moves to the OpenConfirm state. It waits for a KEEPALIVE from the neighbor to confirm the session. Basic parameter checks and capability negotiations are successfully completed in this phase.
* Matches:"Routers have agreed on matching feature sets." - This agreement happens upon successful validation of the OPEN messages exchanged.
* Established:This is the final, stable state where BGP peering is successful. Both routers have accepted each other's parameters via the OPEN messages and confirmed the session with KEEPALIVEs. In this state, the routers can exchange UPDATE messages containing routing information.
* Matches:"The router is able to process update messages."

NEW QUESTION # 18
Review the diagram and existing configuration of RouterA above. Which configuration changes are necessary to permit load balancing between RouterA and RouterB? (Selecttwo) Exhibit.

Answer: A,B

Explanation:
Analyze Topology and Existing Configuration:
* RouterA (AS 64500) peers with RouterB (AS 64512) using eBGP.
* Peering is configured between loopback interfaces (RouterA Lo0 10.3.0.3 to RouterB Lo0 10.255.0.12).
* Two parallel physical links connect the routers (10.255.102.0/30 and 10.255.102.4/30).
* RouterA has two static routes pointing to RouterB's loopback (10.255.0.12/32), one via each physical link's next hop (10.255.102.1 and 10.255.102.5). This provides reachability to the BGP peer address over both paths.
* RouterA's BGP config activates the neighbor 10.255.0.12 for IPv4 unicast but is missing key commands for stable loopback peering and load balancing.
Goal:Permit load balancing for traffic exchanged via BGP between RouterA and RouterB. This requires BGP ECMP (Equal Cost Multi-Path).
Requirements for eBGP ECMP over Loopbacks:
* Stable Peering:Peering must use loopback addresses. This requires:
* update-source loopback <id>: To source BGP TCP packets from the loopback IP.
* ebgp-multihop <ttl>: Because loopbacks are not directly connected (TTL > 1 needed).
* ECMP Enabled:BGP must be configured to allow multiple paths in the routing table. This requires:
* maximum-paths <n> (or maximum-paths ebgp <n>): To allow more than the default 1 path.
* Equal Paths:BGP must see multiple paths to thesameprefix learnedfrom RouterBthat are considered equal based on BGP path selection attributes (Weight, Local_Pref, AS_Path, Origin, MED, etc.). Since routes are learned from the same neighbor IP (RouterB's loopback), these attributes will likely be identical for routes learned via this peering. RouterA already has equal static routestothe BGP next hop (10.255.0.12).

NEW QUESTION # 19
Which issue may becausing the new door locks on the APs to notwork?

A. AT power to the AP is notenough.
B. BT power to the AP is too much.
C. AT power to the AP is too much.
D. AF power to the AP is not enough.

Answer: D

Explanation:
New PoE-powered door locks, connected via the PoE passthrough port on Aruba APs, are not working. We need to find the likely cause related to PoE power.
* PoE Passthrough:An AP feature where the AP, powered by PoE from a switch, provides PoE power out to another device connected to one of its Ethernet ports.
* Power Budget:The AP must receive enough power from the switch via its PoE input (e.g., 802.3af,
802.3at, 802.3bt) to power itselfandmeet the power demand of the downstream device (the door lock).
* PoE Standards Power (Approx. Available to Device):
* 802.3af (PoE): ~13 Watts
* 802.3at (PoE+): ~25.5 Watts
* 802.3bt (PoE++): 51W (Type 3) or 71W (Type 4)
* Analysis:Modern APs (especially Wi-Fi 6/6E) can consume significant power themselves (>15W or
>25W under load). Standard 802.3af PoE (supplying only ~13W) is often insufficient to power both a modern AP and a downstream PoE device like a door lock. The AP will power up, but won't enable PoE output if its input power budget is insufficient.
* Analysis of Options:
* A, B: Too much power (AT/BT) isn't the issue; devices only draw what they need.
* C: AF power (~13W) received by the AP is very likelynot enoughto power both the AP and the door lock.
* D: AT power (~25.5W)mightbe insufficient if the combined load of the AP and lock exceeds this, but AF being insufficient (C) is a more common limitation.
* Conclusion:Insufficient input power to the AP is the most common reason for PoE passthrough failure.
802.3af (PoE) power is often inadequate.

NEW QUESTION # 20
The customer is experiencing periodic uplink congestion between campus-1's AGG-1 and core. This has boon negativelyaffecting voice communications.The VOIP phones edge mark their packets with DSCP EF. The uplink from AGG-1 to core is LAG1.
The customer has already configured the following class and policy on AGG-1:

Based on this policy, which scrip), when deployed on AGG-1. will improve the reliable forwarding of voice trafficbetween AGG-1 and its uplink to the core?

Answer: C

Explanation:
The problem describes uplink congestion affecting VoIP traffic (marked with DSCP EF, value 46) on AGG-
1's LAG1 uplink. The existing configuration classifies this traffic into voip_class and applies voip_policy inbound, setting local-priority 6. To improve reliable forwarding during congestion, VoIP traffic needs strict priority queuing on the egress interface (LAG1).
* Analysis of Options:
* Option A applies a QoS schedule profile globally but doesn't modify the policy's local-priority or apply the schedule profile specifically to the congested LAG.
* Option B modifies voip_policy to set local-priority 7 (mapping DSCP 46 traffic to queue 7) and applies the 8qDwrStrict schedule profile to the egress interface lag 1. In the 8qDwrStrict profile, queue 7 is configured for strict priority, ensuring voice traffic gets precedence over lower-priority traffic during congestion. This aligns with best practices for QoS for VoIP.
* Option C also sets local-priority 7 and applies the schedule profile to lag 1, but the profile itself configures queue 7 with DWRR (Deficit Weighted Round Robin) instead of strict priority, which is less suitable for delay-sensitive voice traffic.
* Option D applies a schedule profile globally and uses DWRR for queue 7.
* Conclusion:Option B is the correct solution because it maps the DSCP EF traffic to the highest local priority (7) and applies a QoS schedule profile to the specific congested uplink (lag 1) that treats queue
7 with strict priority. This ensures voice traffic is prioritized reliably.

NEW QUESTION # 21
Exhibit.

AGG-SW1 and AGG-SW2 are configured with iBGP and eBGP to AS65000. Both agg-sw1 and agg-sw2 useroute-map BGP-EXPORT and ip-prefix list local-export in the bgp configuration.
What must be done on agg-swl for the adjacent router to prefer to route all exported routes by agg-sw2?

A. Add set local-preference 200 to the route-map BGP-EXPORT
B. Add set as-path 65345 65345 65345 65345 to the route-map BGP-EXPORT Match with local-export ip prefix-list.
C. Add set metric 200 to the route-map BGP-EXPORT.
D. Add set as-path prepend 65345 65345 65345 65345 to the route-map BGP-EXPORT Match with local- export Ip prefix-list.

Answer: D

Explanation:
The goal is to make the adjacent router prefer routes exported by AGG-SW2 over AGG-SW1 for iBGP and eBGP routes to AS65000. Both switches use a route-map BGP-EXPORT with an ip-prefix list local-export.
BGP path selection uses attributes like local preference, AS path length, and metric to determine the preferred route.
* Analysis of Options:
* Option A:Setting local-preference 200 affects iBGP route selection within the same AS but has no impact on eBGP peers (external AS65000), as local preference is not advertised externally.
* Option B:Prepending the AS path with 65345 65345 65345 65345 increases the AS path length for routes exported by AGG-SW1, making them less preferred by the adjacent router (both iBGP and eBGP peers) compared to AGG-SW2's routes, which have a shorter AS path.
* Option C:Setting metric 200 affects the MED (Multi-Exit Discriminator), which is used for eBGP route selection within the same AS but is less influential than AS path length and not applicable for iBGP.
* Option D:Incorrect syntax (set as-path without prepend) and does not achieve the desired effect.
* Why Option B is Correct:BGP route selection prioritizes the shortest AS path for both iBGP and eBGP. By prepending AS 65345 multiple times to AGG-SW1's exported routes, AGG-SW1's routes appear less attractive due to a longer AS path, causing the adjacent router to prefer AGG-SW2's routes.
This is a standard BGP traffic engineering technique.
* Relevance to Certification Objectives:
* Routing (16%):Involves designing and troubleshooting BGP routing topologies, including manipulating path attributes like AS path.
* Troubleshooting (10%):Includes remediating BGP routing issues by adjusting route-maps.

NEW QUESTION # 22
Exhibit.

VSX cluster is already configured. Your task is to validate a correct configuration for the Edge-1 switch that is connected to a CCTV provider that will install its switching infrastructure. The CCTV switches do not support STP.
What needs to be configured on the Edge-1 switch ports connecting to CCTV-SW1 and CCTV-SW2 to prevent loop problems with the existing setup with automatic recovery features?

A. configure spanning-tree with udld for CCTV switch ports
B. configure spanning-tree with bpdu-guard timeout values for CCTV switch ports
C. configure lag with lacp fallback for CCTV switch ports
D. configure spanning-tree and TCN-guard timeout for CCTV switch ports

Answer: B

Explanation:
The requirement is to prevent loops on Edge-1 switch ports connected to third-party CCTV switches that do notsupport STP. The solution must also include an automatic recovery feature if a port gets disabled.
* Loop Prevention without STP:When connecting to non-STP devices, standard STP loop prevention (like BPDU Guard) might not work if the connected device doesn't send BPDUs. AOS-CX offers a feature called loop-protect which sends probes to detect loops in non-STP environments.
* Automatic Recovery:Features that disable ports (like BPDU Guard or Loop Protect) often have a timeout or auto-recovery option (port-disable-timer for Loop Protect) allowing the port to automatically re-enable after a configured period.
* Analysis of Options:
* A: LACP fallback applies to LAGs, not general loop prevention.
* B: TCN-guard is an STP feature, irrelevant here.
* C: Suggests spanning-tree with bpdu-guard timeout. BPDU Guard detects loops by listening for BPDUs, which these CCTV switches don't send. However, the timeout featuredoesprovide the required automatic recovery mechanism if the portweredisabled by BPDU Guard.
* D: UDLD detects unidirectional links, not typically bridging loops caused by topology.
* Re-evaluation:The ideal AOS-CX feature is loop-protect with port-disable-timer. Since this isn't explicitly an option, we must evaluate the given choices. Option C is theonlyone that mentions a mechanism (bpdu-guard timeout) providing automatic recovery from a disabled state. While BPDU Guard isn't the right detection mechanism here, it's the closest fit regarding the auto- recoveryrequirement. It's possible the question implicitly assumes some stray BPDUs might trigger it or that it's the intended "best fit" answer despite the detection mechanism mismatch.
* Conclusion:Given the options, Option C is the most plausible because it includes the timeout feature associated with bpdu-guard, fulfilling the automatic recovery requirement, even though BPDU guard itself is not the ideal detection method for loops involving non-STP devices.

NEW QUESTION # 23
When trying to add a now access switch to the network, theswitch port at the aggregation switch is automatically disabled.
What needs to be done to fix this issue?

A. Disable spanning tree bpdu-tilter al the interface level.
B. Disable spanning tree bpdu-guard at the interface level.
C. Disable spanning tree root-guard at the interface level.
D. Disable spanning tree loop-guard at the interface level.

Answer: B

Explanation:
The issue involves a new access switch's port being automatically disabled when connected to an aggregation switch, likely due to a Spanning Tree Protocol (STP) protection mechanism.
* Analysis of Options:
* Option A (Disable bpdu-filter):BPDU filtering prevents BPDUs from being sent or processed, which could cause loops, not resolve the issue.
* Option B (Disable root-guard):Root guard prevents a port from becoming the root bridge but does not cause port disablement in this context.
* Option C (Disable loop-guard):Loop guard prevents alternate ports from becoming designated but is unrelated to port disablement.
* Option D:Correct. Disabling BPDU guard on the aggregation switch's interface prevents it from disabling the port when it receives BPDUs from the new access switch.
* Why Option D is Correct:BPDU guard is an STP feature that disables a port if it receives BPDUs, assuming an unauthorized device is connected. When a new access switch isconnected, it sends BPDUs as part of normal STP operation, triggering BPDU guard on the aggregation switch and disabling the port.

NEW QUESTION # 24
With the configuration oftwo CX 8325 switches in the VSX cluster, how would you prepare a link- aggregation for a 7000 gateway for a zero-touch provision to support protocol-based port redundancy?

Answer: D

Explanation:
The goal is to configure a Link Aggregation Group (LAG) on a VSX cluster (pair of CX 8325 switches) that connects to an Aruba 7000 series gateway undergoing Zero Touch Provisioning (ZTP). The LAG needs to support "protocol-based port redundancy" (LACP) and allow connectivity during ZTP.
* VSX Requirement:Since the LAG connects to two separate physical switches operating as a VSX pair, the LAG must be configured as a Multi-Chassis LAG (MC-LAG) on the switches. This allows the gateway to form a single LAG across both upstream devices. The command multi-chassis under the interface lag <id> context enables this.
* Protocol Redundancy Requirement:"Protocol-based port redundancy" indicates that Link Aggregation Control Protocol (LACP) should be used to dynamically negotiate and manage the LAG bundle between the switches and the gateway. The command lacp mode active enables LACP in active negotiation mode.
* ZTP Requirement:During ZTP, the gateway might not have its full configuration, including LACP settings, enabled immediately. To ensure the gateway can establish basic IP connectivity for ZTP (e.g., reach Activate/Central via DHCP/DNS), the switch ports should allow traffic even if LACP negotiation hasn't completed. The lacp fallback feature enables this, allowing individual LAG member ports to become active if LACP PDUs are not received from the peer.
* Analyzing the Options:
* A)Configures lacp mode active and lacp fallback butlacksthe multi-chassis command required for VSX.
* B)Correctly configures the LAG as multi-chassis, enables lacp mode active, and enables lacp fallback. This meets all requirements.
* C)Configures multi-chassis but uses potentially older or less standard syntax lacp enable and lacp fail-over instead of lacp mode active and lacp fallback.
* D)Lacks the multi-chassis command and uses potentially older/less standard syntax.
* Conclusion:Option B provides the complete and correct configuration using standard AOS-CX syntax to create an MC-LAG on the VSX pair with LACP enabled for redundancy and LACP fallback enabled to support gateway connectivity during ZTP.

inter-switch-link lag 256
keepalive peer 192.168.0.1 source 192.168.0.0 vrf KA
(Snippet 4)
* Establish redundant links between the aggregation and core layers --> router ospf 1 maximum-paths 2 (Snippet 2)
* Extend layer 2 across multiple sites -->

(Snippet 1)
* Identify individual layer 2 segments in an overlay -->
vni 11
vtep-peer 10.1.0.5
vlan 11
(Snippet 3)
Comprehensive Detailed Explanation along with All References available from related to the HPE Campus Access Switching Expert certification objectives at end of each question below:
* Aggregate links across multiple switches:This requirement describes Multi-Chassis Link Aggregation (MC-LAG), where a device forms a LAG to two separate upstream switches that act as a logical pair. In AOS-CX, VSX (Virtual Switching Extension) enables this functionality. Snippet 4 shows commands related to setting up VSX (vsx, role primary, inter-switch-link, keepalive), which is the foundation for MC-LAG.
References:AOS-CX VSX Guide.Relates to "Network Resiliency and virtualization" (8%), "Switching" (19%).
Establish redundant links between the aggregation and core layers:This often involves Layer 3 routing protocols utilizing multiple paths. Snippet 2 (router ospf 1, maximum-paths 2) configures OSPF to use up to two Equal Cost Multi-Paths (ECMP). If redundant links between aggregation and core result in equal OSPF costs, this command enables load sharing and redundancy at Layer 3.
References:AOS-CX IP Routing Guide (OSPF, ECMP). Relates to "Routing" (16%), "Network Resiliency and virtualization" (8%).
Extend layer 2 across multiple sites:VXLAN (Virtual Extensible LAN) is the standard overlay technology for extending Layer 2 segments over an underlying Layer 3 network, enabling L2 adjacency across different physical locations (sites, racks, pods). Snippet 1 shows the basic configuration of a VXLAN tunnel interface (interface vxlan 1, source ip), which is the core component for VXLAN tunneling.
References:AOS-CX VXLAN Guide.Relates to "Switching" (19%), "Connectivity" (9%).
Identify individual layer 2 segments in an overlay:Within a VXLAN overlay, each separate Layer 2 broadcast domain (typically corresponding to a VLAN) is identified by a unique VXLAN Network Identifier (VNI). This VNI tags the encapsulated traffic. Snippet 3 shows the configuration associating VNI 11 with the local VLAN 11 (vni 11, vlan 11). The vtep-peer command is relevant when using EVPN as the control plane.
This configuration directly maps an L2 segment (VLAN 11) to its identifier (VNI 11) within the overlay.

NEW QUESTION # 26
A customer has configured eBGP peering using local AS 65000 with two routers from a CX 6300 VSF stack with thefollowing switch ports:
[ports connecting to router-1 10.10.10.2]

The LAGs are connected lo third-party L2 switches, which are used as a transit network for the remote eBGP routers. To optimise the possible BGP peering issues. The AOS-CX switch Is configured with theglobal settings:

What needs to be done on the AOS_CX switch to enable the bidirectional forwarding with the eBGP peers?

A. Option D
B. Option A
C. Option B
D. Option C

Answer: C

Explanation:
The goal is to enable Bidirectional Forwarding Detection (BFD) for eBGP neighbors 10.10.10.2 and
10.10.20.2 on the AOS-CX VSF stack (AS 65000). Global BFD settings are already configured. We need the specific commands to link BFD state to the BGP neighbor relationship.
* BFD for BGP Configuration:Requires enabling the fall-over bfd parameter for the specific neighbor within the router bgp <asn> configuration hierarchy.
* Analyzing the Options (New Image):
* Option 1 (Top):
router bgp 65000
address-family ipv4 unicast
neighbor 10.10.10.2 fall-over bfd
neighbor 10.10.20.2 fall-over bfd
This enables BFD specifically within the ipv4 unicast address family context for both neighbors. This is a valid configuration location.
* Option 2 (Second):
router bgp 65000
neighbor 10.10.10.2 fall-over bfd
neighbor 10.10.20.2 fall-over bfd
This enables BFD directly under the main neighbor <ip> configuration lines within router bgp 65000. This typically applies BFD to all address families configured for that neighbor relationship (including IPv4 unicast). This is also a valid and common configuration location.
* Option 3 (Third):
int 1/1/1-1/1/2, 2/1/1-2/1/2
fall-over-bfd
Incorrect. Applies BFD configuration under an interface range context, which is not how BFD is linked to BGP sessions.
* Option 4 (Bottom):
interface lag1-2
fall-over bfd
Incorrect. Applies BFD configuration under an interface LAG range context, which is not how BFD is linked to BGP sessions.
* Comparing Valid Options (1 vs 2):Both Option 1 and Option 2 correctly use the fall-over bfd command under router bgp. Option 1 provides per-address-family granularity, while Option 2 applies it to the neighbor generally. Without a specific requirement to enable BFDonlyfor IPv4, applying it at the neighbor level (Option 2) is often simpler and sufficient. Both achieve the goal for the required IPv4 peering. In many documentation examples, the configuration is shown at the neighbor level unless per- AF control is explicitly needed.
* Conclusion:Both Option 1 and Option 2 show valid configuration methods. Option 2 is arguably slightly more common/general when BFD is desired for the overall neighbor relationship.

NEW QUESTION # 27
What is the best practice for using Dynamic Segmentation?

A. Use Dynamic Segmentation only on devices thatare connected to the network via Wi-Fi.
B. Use LUR to assign roles to devices based on their location and DUR to assign roles to devices based on their user identity.
C. Use a combination of role-based access and overlay technologies to create a layered security approach.
D. Use UBT to create isolated networks foe specific typos of devices.

Answer: C

Explanation:
The question asks for the best practice for using Dynamic Segmentation.
* Dynamic Segmentation Overview:It's an architecture that provides unified policy and segmentation for wired and wireless clients by combining role-based access control, traffic tunneling (like UBT), and overlay technologies (like VXLAN/GRE). Policies are enforced centrally, typically at an Aruba Gateway.
* Analysis of Options:
* A: UBT is a component, but Dynamic Segmentation encompasses more than just creating isolated networks with UBT.
* B: Correctly describes the core principle: using a combination of role-based access (for defining whogetswhatpolicy) and overlay technologies (for transporting traffic to the policy enforcement point and providing segmentation). This creates a layered security approach.
* C: Incorrect. A key benefit isunifiedpolicy across both wired and wireless access.
* D: LUR and DUR are role types, but how they are assigned isn't the fundamental description of Dynamic Segmentation itself.
* Conclusion:Option B accurately captures the essence of Dynamic Segmentation as a best practice approach, integrating role-based policies with overlay networking for secure, unified access control.

NEW QUESTION # 28
Match the BGP connection states to the conditions that could have caused that state.

Answer:

Explanation:

Explanation:
The last keepalive is less than 3 times the negotiated holddown timer. -->established The router has not received a response. The neighbor might be unreachable. -->active The router is waiting for an initial response from the neighbor. -->connect The router starts listening for a connection. -->idle This question requires matching specific BGP connection states from the BGP Finite State Machine (FSM) to descriptions of the router's activity or condition in those states.
* Idle:This is the starting state. The BGP process is administratively up but is not actively trying to connect. It refuses all incoming BGP connection attempts but listens for a start event (like configuration or operator initiation) or potentially listens for incoming connections if configured for passive peering.
* Matches:"The router starts listening for a connection." (This describes the passive aspect of the Idle state before active attempts begin).
* Connect:In this state, BGP is actively trying to establish a TCP connection with the peer. It has initiated the TCP three-way handshake and is waiting for it to complete, or it is waiting for a remote peer to initiate the TCP connection.
* Matches:"The router is waiting for an initial response from the neighbor." (Specifically, waiting for the TCP handshake to complete).
* Active:If the TCP connection attempt in the Connect state fails (e.g., timeout), the router transitions to the Active state. In this state, it will periodically retry establishing the TCP connection while also listening for an incoming connection from the peer. This state indicates repeated failures to establish TCP connectivity.
* Matches:"The router has not received a response. The neighbor might be unreachable." (This reflects the condition in the Active state where connection attempts fail, suggesting the neighbor is unreachable at the TCP level).
* Established:This is the final, operational state where the TCP connection is up, BGP session parameters have been successfully negotiated via OPEN messages, and KEEPALIVE messages are being exchanged. Routing information (UPDATEs) can be exchanged. The condition described implies the session is healthy and timers are being maintained.
* Matches:"The last keepalive is less than 3 times the negotiated holddown timer." (While phrased slightly unusually, this indicates the holddown timer hasnotexpired because keepalives are being received within the expected window (Holddown Timer = ~3 * Keepalive Interval). This confirms the session is alive, which is true in the Established state).

NEW QUESTION # 29
You are configuring an SSID thatisusing 802.IX as a security mechanism. Whatis the reason tor using WPA3- Ertorpnse (CCM-128) when deploying Wi-Fi 6 networks?

A. WPA3-Entorprise(CCM-128) is also called WPA3-Entorpnso 192-bit mode. lt is WPA3 only and enforces specific EAP certificate ciphers.
B. WPA3-Enterprise (CCM-128) is also called WPA3-Ente'prise Transition Mode. It will allow WPA2 clients to conned.
C. WPA3-Enterprise(CCM-128) is also called WPA3-Eniarpnse Compatibility Mode. It will allow WPA2 clients to connect.
D. WPA3-Enterprise(CCM-128) is also called WPA3-EnterpriseOnly Mode. There is no support tor WPA2 clients.

Answer: B

Explanation:
The question asks for the reason for using WPA3-Enterprise (CCM-128) when deploying Wi-Fi 6 networks.
* WPA3-Enterprise Modes:
* CCM-128:Uses AES-CCMP-128 (same cipher as WPA2). Its main purpose is to provide a transition path from WPA2 to WPA3. It allows both WPA3-capable and WPA2-only clients to connect to the same SSID. It enforces Protected Management Frames (PMF, 802.11w) when possible(required for WPA3, optional for WPA2). It's often called "Transition Mode" or
"Compatibility Mode".
* GCMP-256:Uses stronger AES-GCMP-256. It operates in "WPA3-Only Mode" and doesnot allow WPA2 clients.
* Wi-Fi 6 (802.11ax) & WPA3:Wi-Fi 6 certification requires support for WPA3.
* Analysis of Options:
* A: Incorrectly calls CCM-128 "192-bit mode" and "WPA3 only".
* B: Correctly calls CCM-128 "Transition Mode" and states it allows WPA2 clients.
* C: Correctly calls CCM-128 "Compatibility Mode" and states it allows WPA2 clients.
"Compatibility Mode" and "Transition Mode" are used interchangeably for this WPA3 mode.
* D: Incorrectly calls CCM-128 "Only Mode" and states no WPA2 support.
* Conclusion:Both Option B and Option C accurately describe WPA3-Enterprise (CCM-128). It is designed as a transition/compatibility mode to allow environments to adopt WPA3 features (like mandatory PMF for capable clients) while still supporting legacy WPA2 clients on the same network during the migration period. Selecting either B or C would be functionally correct based on common terminology.
