Question 1

You can run the user-interface maximum-vty command to configure the maximum number of users who can log in to the device through Telnet simultaneously.



Answer : A

Comprehensive Explanation= The user-interface maximum-vty command is used on Huawei devices to configure the maximum number of simultaneous VTY (Virtual Terminal Line) users who can log in via Telnet. By limiting the number of VTY sessions, the administrator can control how many users are able to access the device at the same time, preventing excessive connections that may overwhelm the device or reduce security.


Question 2

On the network shown in the figure, host A logs in to router A through Telnet and obtains the configuration file of router B through FTP on the remote CLI. How many TCP connections exist on router A?



Answer : B

Router A would have three TCP connections in this scenario:

One for the Telnet session from host A to router A.

One for the FTP control connection to router B.

One for the FTP data connection to transfer the configuration file. These TCP connections facilitate the remote login and file transfer across the network.


Question 3

Which SNMP version focuses on two main aspects, namely security and administration. The security aspect is addressed by offering both strong authentication and data encryption for privacy. The administration aspect is focused on two parts, namely notification originators and proxy forwarders.



Answer : C

SNMPv3 was designed with enhanced security and administration features compared to previous versions. It offers robust authentication and encryption to protect against unauthorized access and eavesdropping, as well as improvements in administration with support for notification originators and proxy forwarders. These advancements make SNMPv3 the preferred version for secure network management.


Question 4

(Which of the following descriptions regarding the STP forwarding state is incorrect?)



Answer : B

STP Forwarding State:

In the forwarding state, a port can:

Send and receive BPDUs (Bridge Protocol Data Units).

Learn source MAC addresses from incoming frames.

Forward frames to their destinations.

Analysis of Options:

Option A: Correct. Ports in the forwarding state send BPDUs to maintain network topology.

Option B: Incorrect. Ports in the forwarding state do learn source MAC addresses.

Option C: Correct. Ports in the forwarding state receive BPDUs.

Option D: Correct. Ports in the forwarding state forward data frames.

Correct Answer:

B . A port in a forwarding state does not learn the source MAC address of a frame is incorrect.


Question 5

What is the length range of an Ethernet_II frame that contains an Ethernet header?



Answer : A

An Ethernet II frame has a standard length range of 64 to 1518 bytes, including the Ethernet header. This range accounts for both the minimum frame size (to prevent collisions) and the maximum frame size (to avoid excessive delay). This specification is in line with IEEE 802.3 standards for Ethernet frames.


Question 6
Question 7

(You can run the "pwd" and "dir" commands on the Versatile Routing Platform (VRP) to view file information in the current directory.)



Answer : B

Command Overview:

The Huawei Versatile Routing Platform (VRP) uses specific commands to manage file systems and view directory contents. While the dir command is used to list files in the current directory, the pwd command is not supported in VRP environments. Instead, the current working directory is displayed as part of the command prompt in VRP.

Command Analysis:

dir Command:

This command is supported and displays the list of files and subdirectories in the current directory. Example:

<Huawei> dir

Output includes filenames, sizes, and other metadata.

pwd Command:

The pwd command is commonly used in UNIX/Linux systems to print the current working directory. However, this command is not available on VRP. VRP automatically shows the current directory in its prompt, making pwd unnecessary.

Correct Answer:

Since only dir is valid, the statement is false. The correct answer is B (FALSE).
