Refer to the exhibits. An engineer is troubleshooting an issue in which the Gig0/2 interface on a Cisco switch named SW2 fails to become the root port. Which two commands must be run on SW2 to resolve this issue? (Choose two.)
I would go for D + E on this one:
A. SW2(config-if)# no spanning-tree cost 4 : the command itself is incorrect, you cannot enter a digit in the command no spanning-tree cost, so this command would not work.
B. SW2(config)# interface Gig0/2 : No need to modify anything on the Gi Interface, as there are no options available to decrease the default cost for a Gi (4 is the default cost).
C. SW2(config-if)# spanning-tree cost 4: it's currently the cost both Fa0/3 and gi0/2 have, so there's no need to apply this command on any interface.
D. SW2(config)# interface Fa0/3 : We need to change the cost on Fa0/3 so it would be this command first.
E. SW2(config-if)# spanning-tree cost 5 : Then we change the cost, it would be a bigger cost than interface Gi0/2.
Removing the (presumably) misconfigured spanning-tree cost 4 command is the more elegant solution. Manually configuring Fa0/3 with cost of 5 will also achieve the desired result of having Gi0/2 interface becoming the root; but is a poorer design choice.
I would remove "spanning-tree cost 4" from fast ethernet. This will cause Fa0/3 to have the default higher cost of 19 and so Gi0/2 will be the preferred one.
