During which step of the CompTIA troubleshooting method do you test the theory to determine the cause of the problem?

  1. Step 1

  2. Step 2

  3. Step 3

  4. Step 4

The correct answer is: Step 3

Step 1 is to identify the problem and Step 2 is to establish a theory of probable cause based on the symptoms observed. Step 3 is when you test the theory by using the appropriate tools and techniques to determine the cause of the problem. Finally, in Step 4, you create an action plan to resolve the problem. Therefore, the correct answer is C. In contrast, A, B, and D are incorrect because they do not involve testing the theory to determine the cause of the problem.
