CCNA: Cisco Certified Network Associate — Question 384

Aside from discarding, which two states does the switch port transition through while using RSTP (802.1w)? (Choose two.)

Answer options

• A. blocking
• B. speaking
• C. listening
• D. learning
• E. forwarding

Correct answer: D, E

Explanation

The correct answers are D (learning) and E (forwarding). In RSTP, a port can transition to the learning state where it begins to learn MAC addresses and then to the forwarding state where it actively forwards traffic. The other options (A, B, C) do not represent valid states in the RSTP process aside from those two.
