CompTIA Network+ (N10-009) — Question 334

A network administrator is unable to ping a remote server from a newly connected workstation that has been added to the network, Ping to 127.0.0.1 on the workstation is failing. Which of the following should the administrator perform to diagnose the problem?

Answer options

• A. Verify the NIC interface status.
• B. Verify the network is not congested.
• C. Verify the router is not dropping packets.
• D. Verify that DNS is resolving correctly.

Correct answer: A

Explanation

The correct answer is A because a failure to ping 127.0.0.1 indicates a problem with the workstation's network interface card (NIC) or configuration. The other options, while potentially relevant to other connectivity issues, do not address the immediate failure of the local loopback test.
