Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 30

In standard STP mode, which of the following ports on non-root switches forward the BPDUs with TC bits set generated by the root switch?

Answer options

• A. Root port
• B. Backup port
• C. Designated port
• D. Alternate port

Correct answer: A

Explanation

The correct answer is A, as the Root port is the port on a non-root switch that has the best path to the root bridge and is responsible for forwarding BPDUs. The Backup port, Designated port, and Alternate port have different roles in the STP process and do not forward BPDUs with TC bits set from the root switch.
