NEW QUESTION # 102
Refer to The exhibit. The network administrator must mutually redistribute routes at the Chicago router to the LA and NewYork routers.
The configuration of the Chicago router is this:
After the configuration, the LA router receives all the NewYork routes, but NewYork router does not receive any LA routes. Which set of configurations fixes the problem on the Chicago router?
- A.
- B.
- C.
- D.
Answer: D
Explanation:
"LA router receives all the NewYork routes but it does not receive any LA routes" because when redistrubuting into EIGRP, we must configure the default metric.
NEW QUESTION # 103
After some changes in the routing policy, it is noticed that the router in AS 45123 is being used as a transit AS router for several service provides. Which configuration ensures that the branch router in AS 45123 advertises only the local networks to all SP neighbors?
A)
B)
C)
D)
- A. Option B
- B. Option D
- C. Option C
- D. Option A
Answer: B
Explanation:
Explanation
By default BGP advertises all prefixes to external BGP neighbors. This means that if you are multi-homed (connected to two or more ISPs) then you might become a transit AS. For example, ISP 2 in AS 200 can send traffic to your router in AS 100 to reach ISP 3 in AS 300 because you advertised prefixes in ISP 3 to ISP 2.
This is what will be seen in the BGP routing table of ISP1:
NEW QUESTION # 104

NEW QUESTION # 110
Which two solutions are used to overcome a flapping link that causes a frequent label binding exchange between MPLS routers? (Choose two)
- A. Increase a session delay to protect the session.
- B. Increase a hold-timer to protect the session.
- C. Increase input queue on links to protect the session.
- D. Create targeted hellos to protect the session.
- E. Create link dampening on links to protect the session.
Answer: D,E
Explanation:
Explanation
To avoid having to rebuild the LDP session altogether, you can protect it. When the LDP session between two directly connected LSRs is protected, a targeted LDP session is built between the two LSRs. When the directly connected link does go down between the two LSRs, the targeted LDP session is kept up as long as an alternative path exists between the two LSRs.
For the protection to work, you need to enable it on both the LSRs. If this is not possible, you can enable it on one LSR, and the other LSR can accept the targeted LDP Hellos by configuring the command mpls ldp discovery targeted-hello accept
NEW QUESTION # 111
Refer to the exhibit.
Which two commands provide the administrator with the information needed to resolve the issue? (Choose two.)
- A. debug snmpv3 engine-id
- B. debug snmp engine-id
- C. debug snmp packet
- D. showsnmpv3 user
- E. Show snmp user
Answer: C,E
NEW QUESTION # 112 
An engineer sets up a DMVPN connection to connect branch 1 and branch 2 to HQ branch 1 and branch 2 cannot communicate with each other. Which change must be made to resolve this issue?
- A. Option B
- B. Option D
- C. Option C
- D. Option A
Answer: B
Explanation:
R1(config)#int tunnel 1
R1(config-if) no ip split-horizon eigrp 100
NEW QUESTION # 113 
Refer to the exhibit. A network administrator configured NTP on a Cisco router to get synchronized time for system and logs from a unified time source The configuration did not work as desired Which service must be enabled to resolve the issue?
- A. Enter the service timestamps log datetime console global command.
- B. Enter the service timestamps log datetime localtime global command.
- C. Enter the service timestamps log datetime synchronize global command.
- D. Enter the service timestamps log datetime clock-period global command
Answer: B
Explanation:
Explanation
If a router is configured to get the time from a Network Time Protocol (NTP) server, the times in the router's log entries may be different from the time on the systemclock if the [localtime] option is not in the service timestamps log command. To solve this issue, add the [localtime] option to the service timestamps log command. Thetimes should now be synchronized between the system clock and the log message timestamps.

NEW QUESTION # 118
Refer to the exhibit.
An administrator is configuring a GRE tunnel to establish an EIGRP neighbor to a remote router. The other tunnel endpoint is already configured. After applying the configuration as shown, the tunnel started flapping. Which action resolves the issue?
- A. Modify the network command to use the Tunnel0 interface netmask
- B. Readdress the IP network on the Tunnel0 on both routers using the /31 netmask
- C. Stop sending a route matching the tunnel destination across the tunnel
- D. Advertise the Loopback0 interface from R2 across the tunnel
Answer: C
Explanation:
In this question we are advertising the tunnel IP address 192.168.12.2 to the other side. When other end receives the EIGRP advertisement, it realizes it can reach the other side of the tunnel via EIGRP.
In other words, it reaches the tunnel destination through the tunnel itself -> This causes "recursive routing" error.
Note: In order to avoid this error, do not advertise the tunnel destination IP address on the tunnel interface to other side.

NEW QUESTION # 119
Refer to the exhibit. Router DHCP is configured to lease IPv4 and IPv6 addresses to clients on ALS1 and ALS2. Clients on ALS2 receive IPv4 and IPv6 addresses. Clients on ALS1 receive IPv4 addresses. Which configuration on DSW1 allows clients on ALS1 to receive IPv6 addresses?
- A. DSW1(config-if)# ipv6 helper address 2002:404:404::404:404
- B. DSW1(config)# ipv6 dhcp relay destination 2002:404:404::404:404 GigabitEthernet 1/2
- C. DSW1(config)#ipv6 route 2002:404:404::404:404/128 FastEthernet 1/0
- D. DSW1(dhcp-config)# default-router 2002:A04:A01::A04:A01
Answer: B
Explanation:
Before configuring the DHCP relay agent on your switch, make sure to configure the device that is acting as the DHCP server. You must specify the IP addresses that the DHCP server can assign or exclude, configure DHCP options for devices, or set up the DHCP database agent.
Enable the IPv6 DHCP relay agent function and specifies the IPv6 address as a destination address to which the client messages are forwarded.
NEW QUESTION # 120
Which feature minimizes DoS attacks on an IPv6 network?
- A. IPv6 Prefix Guard
- B. IPv6 Destination Guard
- C. IPv6 Binding Security Table
- D. IPv6 Router Advertisement Guard
Answer: B
Explanation:
The Destination Guard feature helps in minimizing denial-of-service (DoS) attacks. It performs address resolutions only for those addresses that are active on the link, and requires the FHS binding table to be populated with the help of the IPv6 snooping feature.The feature enables the filtering of IPv6 traffic based on the destination address, and blocks the NDP resolution for destination addresses that are not found in the binding table. By default, the policy drops traffic coming for an unknown destination.
