Exam N10-008 topic 1 question 737 discussion

Establish a theory is the step where checking through each level of the OSI model most likely occurs after identifying the problem. It's all about forming a hypothesis to pinpoint the root cause.

The answer is A

D. If you check through each layer then you are verifying the functionality of each device at each layer.

After, but you'd also go through the OSI model in Verifying Functionality which is also after but not directly after.

Establish a theory of cause.

D. Verify functionality

D. Verify functionality. Once a problem has been identified and a potential solution implemented, the next step is to verify that the solution has resolved the issue and that the affected system or network is functioning correctly. This often involves checking through each level of the OSI model to ensure that all layers of the network stack are functioning as expected and that there are no lingering issues or dependencies affecting overall functionality. Therefore, verifying functionality typically includes checking through each level of the OSI model to ensure proper operation.

Step 2 is establish a theory. Step 1 is identify the problem. The OSI model bit is extraneous detail
