Which two values are used by an RSTP bridge to remove stale BPDU information? (Choose two.)
A. Message Age B. Forwarding Delay C. Hello Time D. Max Age
Explanation: RSTP uses the message age value in conjunction with the max age value to indicate a communication failure and to determine when to flush the MAC table. The message age is the number of seconds elapsed since the most recent BPDU was received. The maximum age timer specifies the maximum expected arrival tie of the hello BPDU. If the maximum age timer expires, the bridge detects that the link to the root bridge has failed and initiates a topology reconvergence.
