Which of the following bridge IDs cannot exist in configuration BPDUs sent by a switch?
Which of the following bridge IDs cannot exist in configuration BPDUs sent by a switch?
The bridge priority field in the Bridge ID is typically set in increments of 4096. This means valid bridge priorities would be 0, 4096, 8192, and so on. Therefore, a bridge priority of 2048 cannot exist in configuration BPDUs sent by a switch.
Correct Answer is C: Using bridge priority increments of 0, 4,096 , 8192 and so on.
Cccccc
answer A is correct
4096 increments meaning 2048 is not possible
In the context of Spanning Tree Protocol (STP), the Bridge ID is composed of two parts: the Bridge Priority and the MAC address of the bridge. The Bridge Priority can range from 0 to 61440 in increments of 4096, which means valid Bridge Priority values are: 0, 4096, 8192, 12288, etc. Evaluating the Options 4096 00-01-02-03-04-CC Valid: 4096 is a valid Bridge Priority. 0 00-01-02-03-04-CC Valid: 0 is a valid Bridge Priority. 2048 00-01-02-03-04-CC Invalid: 2048 is not a valid Bridge Priority because it is not a multiple of 4096. 8192 00-01-02-03-04-CC Valid: 8192 is a valid Bridge Priority. Conclusion The Bridge ID that cannot exist in configuration BPDUs sent by a switch is 2048 00-01-02-03-04-CC.
The Bridge Priority can range from 0 to 61440 in increments of 4096. (2048) is wrong. the correct answer is (C) ==> [2048 00-01-02-03-04-CC]
