N10-009 Question #220: Real Exam Question with Answer & Explanation

Question

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?

Options

• AA switch failed.
• BThe console software needs to be reinstalled.
• CThe cables to the modules need to be replaced.
• DA module failed.

Explanation

The customer's loss of connection to the telephone system, despite the console's ability to reach individual modules and the switches functioning, indicates a critical hardware failure within the system itself.

Common mistakes.

• A. The statement explicitly mentions that the administration console is connected to multiple switches and that rebooting a switch shows solid link/activity lights, suggesting the switches are functional.
• B. The support team's ability to remotely connect to the administration console and its success in connecting to individual modules indicates that the console software is functioning correctly.
• C. The console's ability to successfully connect to individual modules directly implies that the cables connecting the console to those modules are not faulty.
