Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 77

Which of the following port status may exist on an STP-enabled switch?

Answer options

• A. Forwarding
• B. Listening
• C. Discarding
• D. Disabled

Correct answer: A, B

Explanation

The correct answers, A (Forwarding) and B (Listening), are both valid port statuses in the Spanning Tree Protocol (STP) process, where a port can either actively forward traffic or listen to BPDUs. Options C (Discarding) and D (Disabled) are not included in the correct answers because they represent states that do not allow forwarding or listening of traffic.
