How could he recreate the issue without already establishing a PROBABLE cause? Him recreating this issue is testing the theory. Next step in my opinion should be Implementing a solution.

If you're able to duplicate an issue, it doesn't technically mean you found a solution. He would still need to establish a theory of probable cause first.

Duplicating the issue is part of the 1st step: "Identify the problem". If you've succeeded in doing it, that leads you to the second step "Establish and test a theory", and you need to test it. Just remember that you can have many causes for an issue. The fact you've duplicated it using one of the possible causes, doesn't mean you have a solution

Answer is D: 2. Establish a Theory of Probable Cause I’d like to start by pointing out the impreciseness of the words in this step. Words such as theory and probable indicate a guess on your part, even if it is a guess backed by data. The way this step is written acknowledges that the root cause (step one) may not have been accurately identified. However, the cause is specific enough to begin troubleshooting. This stage may require significant research on your part. Vendor documentation, your organization’s own documentation and a good old-fashioned Google search may all be required to provide the basis for your theory. Specific steps here may include: Questioning the obvious Considering multiple approaches, including top-to-bottom or bottom-to-top for layered technologies (such as networks) - key take way here is, the problem is an application (layer 7) hence, top to bottom approach
