CompTIA Network+ (N10-008) — Question 487

While troubleshooting a network outage, a technician discovers symptoms that indicate a patch cable is connecting the core switch to the router. A network engineer confirms the theory is plausible, and the technician tests the cable. The cable passes the test, and the technician properly plugs the cable back into the correct network ports. However, the network outage continues. Which of the following is the NEXT step the technician should take to troubleshoot the network outage?

Answer options

• A. Establish a new theory.
• B. Verify full system functionality.
• C. Establish a plan of action.
• D. Continue to work the original theory.

Correct answer: A

Explanation

The correct answer is A because when the current theory does not resolve the issue, the technician should develop a new hypothesis to explore other potential causes. Options B, C, and D are not appropriate as they either focus on confirming the original theory or do not advance the troubleshooting process effectively.
