CompTIA Network+ (N10-008) — Question 505

A customer lost the connection to the telephone system. The administration console is configured with multiple network interfaces and is connected to multiple switches. The network administrator troubleshoots and verifies the following:

• The support team is able to connect remotely to the administration console.
• Rebooting the switch shows solid link and activity lights even on unused ports.
• Rebooting the telephone system does not bring the system back online.
• The console is able to connect directly to individual modules successfully.

Which of the following is the most likely reason the customer lost the connection?

Answer options

• A. A switch failed.
• B. The console software needs to be reinstalled.
• C. The cables to the modules need to be replaced.
• D. A module failed.

Correct answer: A

Explanation

The most probable cause of the lost connection is a switch failure, as the administration console can connect remotely and to individual modules, indicating that the console itself is functioning. The other options are less likely since rebooting the switch shows solid link lights, suggesting that the issue is not with the cables, modules, or the console software.
