A user is having trouble accessing files on the network. A technician suspects the issue is a result of a failed NIC. Which of the following steps should the technician take to troubleshoot this issue?

Answer options

• A. Document key findings, actions, and outcomes.
• B. Establish a theory of probable cause.
• C. Test the theory to determine the cause.
• D. Identify the problem and act.
• E. Verify system functionality.

Correct answer: C

Explanation

The correct step is to test the theory to determine the cause, as this directly addresses the suspected NIC failure. Documenting findings, establishing a theory, identifying the problem, and verifying system functionality are all important, but they come before testing the theory to pinpoint the actual issue.
