Final answer:
The highest STP bridge priority value of 65535 would make a switch least likely to be elected as the root bridge within a LAN topology using STP.
The correct answer is D) 65535,
Step-by-step explanation:
If you want the switch to be least likely to be selected as the root bridge in a LAN topology using the Spanning Tree Protocol (STP), you should choose the highest possible priority value.
In STP, the bridge priority value is used in conjunction with the switch's MAC address to determine the root bridge, with lower values having a higher chance of becoming the root. Therefore, among the options provided:
The correct answer is D) 65535, as it is the highest value and will make it the least likely for that switch to be elected as the root bridge.
STP uses the bridge priority value to maintain a loop-free network topology by selecting a single switch to act as the root bridge. The root bridge serves as a reference point for all path calculations within the network to prevent loops.
