CompTIA Network+ (N10-009) — Question 187

A network administrator is troubleshooting a connection between two switches that is experiencing intermittent errors. The administrator needs to determine which port on the remote switch the faulty cable is connected to. Which of the following is the best tool to use to identify the error?

Answer options

• A. tracert
• B. LLDP run
• C. nmap
• D. ping

Correct answer: B

Explanation

The correct answer is B, LLDP run, as it allows the administrator to identify the connected devices and their respective ports on the switch. The other options, such as tracert, nmap, and ping, do not provide information about the physical connection between switches and are not suited for diagnosing port-related issues.
