Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Proposal-agreement handshake mechanism
Why this is correct
The proposal-agreement handshake allows immediate downstream state transitions.
- ✗
Mandatory 15-second listening timer enforcement
Why it's wrong here
Listening timers slow down legacy STP and are eliminated in RSTP.
- ✗
Centralized root bridge polling
Why it's wrong here
RSTP operates via distributed BPDUs, not centralized polling.
- ✓
Support for point-to-point link synchronization
Why this is correct
Point-to-point links allow rapid full-duplex transitions without waiting for Max Age timers.
- ✗
Periodic topology change broadcasting by root bridges
Why it's wrong here
Topology changes are event-driven, not periodically broadcasted.
