Huawei Certified ICT Associate – Data Center Network (HCIA-DCN) — Question 152

Which of the following statements is true about the edge port in RSTP?

Answer options

• A. Edge ports participate in RSTP calculation.
• B. Interconnected ports between switches must be configured as edge ports.
• C. The edge port discards the received configuration BPDUs.
• D. The edge port can directly transition from the Disabled state to the Forwarding state.

Correct answer: C

Explanation

The correct answer is C because edge ports, which are typically connected to end devices, do not process configuration BPDUs and instead assume a state of forwarding immediately. Option A is incorrect as edge ports do not participate in RSTP calculations. Option B is also wrong since inter-switch links should not be configured as edge ports. Option D is inaccurate because while edge ports can transition quickly, they do not move from Disabled to Forwarding directly.
