CompTIA Network+ (N10-009) — Question 518

Which of the following stages of the troubleshooting methodology involves considering multiple approaches?

Answer options

• A. Verify full functionality.
• B. Implement the solution.
• C. Document the findings and actions.
• D. Establish a theory of probable cause.

Correct answer: D

Explanation

The correct answer is D because establishing a theory of probable cause is the stage where multiple potential solutions are assessed before deciding on an approach. The other options pertain to later stages of troubleshooting, such as verifying functionality, implementing a solution, and documenting results, which do not involve considering multiple approaches.
