What does the second step of the CompTIA troubleshooting method involve?

  1. Planning resolution action

  2. Testing the theory

  3. Establishing a theory of cause

  4. Documenting outcomes

The correct answer is: Establishing a theory of cause

The second step of the CompTIA troubleshooting method involves establishing a theory of cause. This means that before taking any action, you must first come up with a hypothesis or possible explanation for the issue. Option A, planning resolution action, is incorrect because this involves creating a concrete plan of action after the theory of cause has been established. Option B, testing the theory, is incorrect because this takes place in the third step of the method. Option D, documenting outcomes, is incorrect because this takes place in the final step of the method, after the issue has been resolved.
