Refer to the exhibit. Which switch becomes the root of the spanning tree?
The exhibit lists each switch's bridge ID: Switch 1 at priority 32778, Switch 2 at 24586, Switch 3 at 28682, and Switch 4 at 64000. Spanning Tree Protocol elects the switch with the numerically lowest bridge ID as the root bridge, and Switch 2's BID of 24586 is the lowest of the four, so Switch 2 becomes the root of the spanning tree.
