CompTIA Network+ (N10-008) — Question 91

An IT technician suspects a break in one of the uplinks that provides connectivity to the core switch. Which of the following command-line tools should the technician use to determine where the incident is occurring?

Answer options

• A. nslookup
• B. show config
• C. netstat
• D. show interface
• E. show counters

Correct answer: D

Explanation

The 'show interface' command is essential for checking the status of interfaces on a switch, allowing the technician to identify any issues with the uplinks. The other commands do not provide relevant information about interface connectivity, as 'nslookup' is for DNS resolution, 'show config' displays configurations, 'netstat' shows network connections, and 'show counters' provides statistics but not interface statuses.
