CompTIA Network+ (N10-008) — Question 205

A help desk technician is concerned that a client's network cable issues may be causing intermittent connectivity. Which of the following would help the technician determine if this is the issue?

Answer options

• A. Run the show interface command on the switch.
• B. Run the traceroute command on the server.
• C. Run iperf on the technician's desktop.
• D. Ping the client's computer from the router.
• E. Run a port scanner on the client's IP address.

Correct answer: A

Explanation

Running the show interface command on the switch provides valuable information about the status of the network interfaces, helping to identify issues related to the network cable. The other options, such as traceroute or pinging, do not directly assess the physical layer connection quality, and iperf is used for measuring bandwidth rather than diagnosing cable problems.
