Exam N10-009 topic 1 question 7 discussion

I just passed N10-009 this past weekend, 11.9.24 using these questions. I studied the 159 questions and they were a lifesaver. I also got all 6 scenario questions, the first one was very complicated and I gave up and moved on. I saved the scenarios for last and they took 50 min to go through. Study all 159 questions the answers given. It's worth it. I got a 836 for my score even not doing well with a couple of the scenario questions!!

https://www.comptia.org/blog/troubleshooting-methodology 1. Identify the problem 2. Establish a theory of probable cause ===> Answer : A 3. Test the theory to determine the cause 4. Establish a plan of action to resolve the problem and identify potential effects 5. Implement the solution or escalate as necessary 6. Verify full system functionality and, if applicable, implement preventive measures 7. Document findings, actions, outcomes and lessons learned

Here is my view on this one. Designing a methodical process to check each layer of the OSI model falls under "Create a plan of action." This step involves developing a thorough plan that includes troubleshooting each OSI layer to pinpoint the issue. You can look at it like drawing up a detailed blueprint for troubleshooting. You're outlining how you'll approach each layer if necessary.

The correct answer is A (check Nyang2´s answer)

A. Establish a theory

A. Establish a theory According to the CompTIA troubleshooting methodology, once the problem has been identified, the next step is to establish a theory of probable cause. This involves systematically analyzing the problem and narrowing down potential causes. Checking through each level of the OSI model is a common practice at this stage to identify where the issue might be occurring.

The next step after identifying the problem is establishing a theory of probable cause which can include considering multiple approaches: top-to-bottom or bottom-to-top OSI model approaches. Verify functionality would include OSI model but only after implementing the solution which hasn't happened in this question

The reason it is said to be A is because from comptias website under establish a theory "The steps in this phase are: Questioning the obvious to identify the cause of the problem Considering multiple approaches, including top-to-bottom or bottom-to-top for layered technologies (such as networks)"

Correction, it's D Verifying using the OSI model is explicitly mentioned in the troubleshooting methodology.

Notice or identify problem, hypothesize possible cause, look for problem testing the possible cause, fix the problem, only then you verify the functionality.

is the answer not D?

When verifying functionality after identifying a network problem, Checking each layer of the OSI model would be good to make sure the issue is fully resolved at every level of communication - please correct me if I am wrong

The correct answer is A: Establish a theory.
