Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 84

As specified by the RSTP protocol, when a root port fails, which type of port will function as a new root port and enters the forwarding state without any delay?

Answer options

• A. Forwarding Port
• B. Alternate Port
• C. Backup Port
• D. Edge Port

Correct answer: B

Explanation

The correct answer is B, the Alternate Port, because it is specifically designed to take over as the root port without any delay when the primary root port fails. The other options, such as Forwarding Port, Backup Port, and Edge Port, do not have the same functionality under RSTP for immediate transition to forwarding state upon a root port failure.
