CompTIA Network+ (N10-008) — Question 625

Which of the following steps of the troubleshooting methodology would most likely include checking through each level of the OSI model after the problem has been identified?

Answer options

• A. Establish a theory.
• B. Implement the solution.
• C. Create a plan of action.
• D. Verify functionality

Correct answer: A

Explanation

The correct answer is A, as establishing a theory involves analyzing the problem in depth, which includes checking the OSI model layers to identify potential causes. Options B, C, and D refer to actions taken after the problem has been analyzed and a theory has been established, thus they do not involve the examination of the OSI model.
