Exploring Troubleshooting Approaches in Network Issues

How to troubleshoot network issues starting from the Physical layer of the OSI model?

a. Random layer approach

b. Divide and conquer approach

c. Bottom up approach

d. Top down approach

Answer: c. Bottom up approach

Answer:

When dealing with network issues and starting troubleshooting from the Physical layer of the OSI model, the best approach is the Bottom up approach.

Starting troubleshooting from the Physical layer of the OSI model is crucial in diagnosing and resolving network issues. The Bottom up approach involves inspecting the different layers of the OSI model from the bottom most layer and then moving to successive higher levels.

By following the Bottom up approach, you can systematically analyze each layer to identify where the problem lies. This method ensures that you address any underlying issues at the lower layers before moving on to higher layers.

Choosing the correct troubleshooting approach is essential in efficiently resolving network issues and restoring Internet access to users within the network. By applying the Bottom up approach, you can effectively track down the root cause of the problem and take appropriate measures to resolve it.
