Refer to the exhibit. Which switch becomes the root bridge?
In determining the root bridge in a Spanning Tree Protocol (STP) topology, the switch with the lowest bridge priority becomes the root bridge. If there is a tie in the bridge priority, the switch with the lowest MAC address is selected. Here, SW2 and SW4 both have the same bridge priority of 8192, which is lower than the priorities of SW3 and SW4 with 61440. Between SW2 and SW4, SW2 has the lower MAC address (05:52:bd:0c:be:69 compared to 05:4a:f7:06:33:22). Therefore, SW2 will be chosen as the root bridge.
A is correct. Smallest bridge priority an smallest mac address.
lowest priority, and lowest MAC address
A is correct
