Question 67/132
Which of the following BIDs cannot be contained in a configuration BPDU sent by a switch?
Correct Answer: B
Comprehensive Explanation: In STP (Spanning Tree Protocol), the Bridge ID (BID) is used to uniquely identify a switch in the network. It consists of a bridge priority and a MAC address. A BID with a bridge priority of 0 and a MAC address starting with 00-01 is reserved for special purposes and cannot be used in a configuration BPDU (Bridge Protocol Data Unit) sent by a regular switch. This prevents conflicts with reserved MAC addresses.
