CompTIA Network+ (N10-007) — Question 247

A technician is diagnosing an issue with a new T1 connection. The router is configured, the cable is connected, but the T1 is down. To verify the configuration of the router, which of the following tools should the technician use?

Answer options

• A. Loopback adapter
• B. Cable tester
• C. Tone generator
• D. Multimeter

Correct answer: A

Explanation

The correct answer is A, the Loopback adapter, as it allows the technician to test the router's configuration by simulating a T1 connection. The other options, such as a Cable tester, Tone generator, and Multimeter, are useful for physical layer testing but do not specifically verify router configuration.
