| Question ID 18547 | Which flag in a configuration BPDU instructs all switches to shorten their bridge table aging
process from the default 300 seconds to the current forward delay value?
|
| Option A | topology change bit
|
| Option B | topology change acknowledgment bit
|
| Option C | priority bit
|
| Option D | max-age bit
|
| Correct Answer | A |
Explanation Explanation: The Root Bridge continues to set the Topology Change flag (TCN bit) in all Configuration BPDUs that it sends out for a total of Forward Delay + Max Age seconds (default = 35 (20+15) seconds). This flag instructs all bridges to shorten their MAC address table (Bridge table) aging process from the default value of 300 seconds to the current Forward Delay value of the bridge (default=15 seconds). The TCA flag is set by the upstream bridge to tell the downstream bridges to stop sending TCN BPDUs. The TC flag is set in configuration BPDU by the Root Bridge to shorten the bridge table age-out period from default 300 seconds to Forward Delay seconds.
