JN0-349 Exam - Question 21


Which two statements about Layer 2 loop prevention protocols are correct? (Choose two.)

Show Answer
Correct Answer: CD

RSTP (Rapid Spanning Tree Protocol) has capabilities that enhance its performance over the basic STP (Spanning Tree Protocol). With RSTP, a designated port can transition to the forwarding state immediately without having to wait for the traditional protocol times to expire, which is a significant improvement. Additionally, RSTP uses point-to-point and edge port designations to efficiently manage the network topology and prevent Layer 2 loops.

Good link - thanks. STP (not RSTP) does not support 'Edge Ports' in case someone wondered.
