CompTIA Network+ (N10-008) — Question 701

A network administrator is investigating a network connectivity issue. The administrator runs a command to view the status of the network cards. The administrator receives the following output:

RX packets:45332 errors: 45332 dropped:0 overruns 0 frame:0

Which of the following should the administrator troubleshoot based on the output?

Answer options

• A. Physical layer components
• B. VLAN tagging configuration
• C. Buffers on the card filling up
• D. TCP/IP address settings

Correct answer: A

Explanation

The output indicates that there are a significant number of RX errors, which typically points to issues at the physical layer, such as damaged cables or malfunctioning network cards. The other options, like VLAN tagging, buffer issues, or TCP/IP settings, would not typically result in such a high number of RX errors without corresponding drops or overruns.
