Which of the following descriptions about the P/A mechanism in RSTP are correct? (Multiple choice)
The correct answer is A. In RSTP, the main purpose of the P/A mechanism is to speed up the speed at which the upstream port enters the Forwarding state. B. In RSTP, when the switch receives the RST BPDU with the Agreement bit set from the opposite end, it will immediately put the designated port into the Forwarding state. See the full explanation below for the reasoning.
