Answers

G0/0/2 of SWC

B.

G0/0/3 of SWB

Answers
B.

G0/0/3 of SWB

C.

G0/0/1 of SWC

Answers
C.

G0/0/1 of SWC

D.

G0/0/3 of SWA

Answers
D.

G0/0/3 of SWA

Suggested answer: B

Explanation:

Comprehensive SWA has the lowest Bridge ID and is the root bridge. In this topology, G0/0/2 of SWA and G0/0/1 of SWC are forwarding ports. Since G0/0/3 of SWB provides an alternate path to the root bridge, it will be placed in a blocking state to prevent network loops. The Spanning Tree Protocol ensures that only the most efficient path to the root bridge is active, and alternate paths are blocked until needed.
