Question

You are informed that all the users within the network are unable to access the Internet. You decide to start troubleshooting from the Physical layer of the OSI model. Which of the following approaches would you use to troubleshoot this problem?a. Random layer approach
b. Divide and conquer approach
c. Bottom up approach
d. Top down approach

Answer 1

Answer: c. Bottom up approach

Explanation:

As the users are unable to access the internet so in such a scenario it is required to inspect the different layers of the OSI model in order to know where the problem actually lies.

So the best situation would be when we start with the bottom most layer and then move to successive higher levels. As without checking the problems at the underneath layers we cannot be ascertain that the problem is caused by layers above,

Option C is correct

Option A is incorrect as we cannot pick up any random layer to inspect for the problem.

Option B is incorrect as there is nothing to do with divide and conquer approach as we are dealing with layers of network protocol.

option D is incorrect because top down approach would not be effective in identifying and tracking down the problem.
