If Sw-E is the root for all VLANs, which of the following is a valid path from host A to Server 1?

Exhibit:

A.
Sw-A, Sw-D

B.
Sw-A, Sw-E, Sw-D

C.
Sw-A, Sw-B, Sw-C, Sw-D

D.
Sw-A, Sw-E, Sw-C, Sw-D

E.
Sw-A, Sw-E, Sw-A, Svv-D

Explanation:

All the traffic must go through root switch so the shortest path should be Sw-A -> Sw-E -> Sw-C -> Sw-D (notice that traffic can not go through Sw-A -> Sw-E and back to Sw-A again)
