Question
A cloud engineer received a support call indicating web apps running on an IaaS server are unavailable. The engineer took the following trouble-shooting steps:
- Hypothesized the server outage is considered to be the cause of the
problem.
- Performed rollback of applied patches.
- Ensured all web apps are running correctly.
- Documented the incident.
Which of the following troubleshooting methodology steps did the cloud engineer overlook?
Options
- AEstablish the theory of probable cause.
- BEstablish a plan of action and implement the solution.
- CTest the theory to determine the cause.
- DVerify system functionality.

Why each option
The cloud engineer overlooked the troubleshooting step of testing the theory to determine the actual cause of the web app unavailability before implementing a solution.
The engineer did establish a theory of probable cause by hypothesizing that a server outage was the problem's cause.
The engineer did establish a plan and implement a solution by performing a rollback of applied patches.
The engineer hypothesized the server outage was the cause, then immediately implemented a solution (rollback of patches). However, they did not explicitly test their initial theory to confirm the server outage (or the patches causing it) was indeed the root cause before proceeding with a solution, which is a critical step in systematic troubleshooting to verify the hypothesis.
The engineer did verify system functionality after the fix by ensuring all web apps were running correctly.
