Refer to the exhibit.
Which two statements about the hardware components are true? (Choose two.)
- A. 2 is a USB 5-pin mini USB Type B to USB Type A console cable.
- B. 1 is a USB Type A port.
- C. 2 is an RJ-45 to USB Type A console cable.
- D. 3 is a USB Type A port.
- E. 3 is a USB 5-pin mini USB Type B port.
Answer: A,E
Explanation:
The image provided shows a networking device connected to a laptop via a console cable. Based on the visual indicators and standard port designs:
C . 3 is a USB 5-pin mini USB Type B port: The port labeled "3" on the laptop is smaller than a standard USB Type A port, which suggests it is a mini USB Type B port, commonly used for connecting to networking devices for console access.
E . 2 is a USB 5-pin mini USB Type B to USB Type A console cable: The cable labeled "2" has one end that fits into the mini USB Type B port on the laptop (as identified in point 1), and the other end, which is not clearly visible in the image, is inferred to be a USB Type A connector that would typically connect to a computer's USB port.

- A. show environment
- B. show run
- C. show inventory
- D. show version
- E. show archive
Answer: C,D
Explanation:
The commands that can be used to identify the serial number of a Cisco router are show inventory and show version.

The show version command displays the router's configuration, including the version of the operating system, the last reboot reason, and the hardware serial number, which is listed as the "Processor board ID" in the command output2. These commands are essential for network administrators to document and manage network equipment.
NEW QUESTION # 44
What is the primary method for recovering or upgrading a Cisco network device system image?
- A. the xmodem command
- B. USB storage
- C. FTP
- D. the tftpdnld command
Answer: D
Explanation:
The tftpdnld command in Cisco IOS is specifically designed for recovering or upgrading a system image. Here's how it's the most effective method:
Purpose: The tftpdnld command directly initiates a TFTP download of a new system image and stores it in memory. This is ideal for replacing a corrupt image or upgrading to a newer version of Cisco IOS.
ROMmon: The tftpdnld command can often be used from ROMmon mode, which is essential when the existing image is unusable.
Efficiency: It streamlines the image transfer process specifically using TFTP, which is commonly used for Cisco IOS images.
Why other options are less ideal:
USB storage: While some newer Cisco devices may allow direct loading of an IOS image from USB, this isn't universally supported and often requires specific boot commands.
FTP: FTP (File Transfer Protocol) can be used for file transfers, but it's not as commonly used as TFTP in the context of Cisco IOS image recovery. The tftpdnld command offers a more tailored solution for this purpose.
the xmodem command: XMODEM is a legacy file transfer protocol that is slower and less reliable than TFTP, especially for larger files like Cisco IOS images.
NEW QUESTION # 45
Which type of memory stores the decompressed form of Cisco IOS Software and the running configuration?
- A. flash
- B. ROM

NEW QUESTION # 46
What does Cisco use for Return Materials Authorization tracking of field-replaceable parts?
- A. RMA number
- B. serial number
- C. FRU number
- D. product number
Answer: A
Explanation:
RMA (Return Materials Authorization) is a tracking number that is assigned to a product that is being returned to the manufacturer for repair or replacement. The RMA number allows the manufacturer to track the progress of the return and ensure that the product is returned to the correct customer.
NEW QUESTION # 47
Which two commands are valid for copying a saved configuration to RAM? (Choose two.)

NEW QUESTION # 49
Which two statements about Telnet and SSH are true? (Choose two.)
- A. A Telnet network management connection is dropped when a router reboots.
- B. Telnet is a protocol that provides a secure remote access connection to network devices.
- C. Telnet is preferred over SSH for security reasons.
- D. SSH uses the well-known TCP port 23 for its communication.
- E. SSH is a protocol that provides a secure remote access connection to network devices.
Answer: A,E
Explanation:
A . Correct. SSH, or Secure Shell, is indeed a protocol that provides a secure remote access connection to network devices. It encrypts the data to ensure secure transmission over insecure networks like the internet1.
C . Correct. Telnet connections are not secure and are terminated when a router reboots. This is because Telnet does not have any mechanism to maintain the connection in case of network interruptions or device reboots1.
B, D, and E are incorrect because: B. SSH uses TCP port 22 by default, not port 23, which is used by Telnet1. D . Telnet does not provide a secure connection; it transmits data in plain text, which can be intercepted easily1. E. SSH is preferred over Telnet for security reasons because it provides encrypted connections and authentication mechanisms, which Telnet does not1.

NEW QUESTION # 50
What are two standard fiber-optic connectors? (Choose two.)
- A. multidimension
- B. Lucent
- C. subscriber
- D. rollover
- E. crossover
Answer: B,C
Explanation:
Two standard fiber-optic connectors are Lucent Connectors (LC) and Subscriber Connectors (SC). The Lucent Connector, commonly referred to as LC, was developed by Lucent Technologies and is characterized by its small form factor with a 1.25mm ferrule. It is widely used in high-density applications due to its compact size and square shape1. The Subscriber Connector, or SC, is known for its push-pull latching mechanism and uses a 2.5mm ferrule. It is a square-shaped, duplex connector that has been a dominant fiber optic connector for decades due to its performance and reliability12.
