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?

I would use the bottom up approach to troubleshoot this problem

Explanation:

Troubleshooting of network issues can sometimes be resolved in a few simple steps. For some issues, using one approach may work better than others. However, in this case, I should use the bottom-up approach to troubleshoot this problem. In the bottom-up approach, the physical layer is the initial point in which I will begin troubleshooting and will go up layer by layer to the Application layer. The physical layer is where I will spend most of my time checking whether all the network cables are plugged in and whether all the physical components are working correctly. After I am sure that all elements associated in this layer are in perfect condition, I can shift focus to the next layer above.
