Q.No.3. [Marks 20) a) Ali was just hired as a Senior Network Consultant at a large hospital in Nowshera, KP. Ali starts his job, but after some days, the network has some problems. He asks one of the junior administrators for a network map so he can troubleshoot the network. That person tells him that the old Senior Administrator (who just resigned) had them with him and now no one can find them...ouch! Doctors are calling every couple of minutes because they can't get the necessary information they need to take care of their patients. What should Ali do? b) Consider the network shown in figure 4, write CLI commands to show the directly connected devices of switch 1, 2 and 3. What are the two CDP global parameters and how can you change these two parameters using CLI.
