Huawei Certified ICT Professional – Data Center Network (HCIP-DCN) — Question 7

On a network, some switches are enabled with RSTP and some switches are enabled with STP. What will happen? (Choose all that apply.)

Answer options

• A. A Huawei switch changes from RSTP to STP. After the STP-enabled switch is removed from the network, the RSTP-enabled switch can be moved back to the RSTP mode.
• B. A Huawei switch changes its mode from STP to RSTP. After the RSTP-enabled switch is removed from the network, the STP-enabled switch can be moved back to the RSTP mode.
• C. STP and RSTP is compatible each other, but the rapid convergence of RSTP is unavailable.
• D. STP and RSTP calculation are performed independently.

Correct answer: A, C, D

Explanation

The correct answers are A, C, and D because RSTP is designed to work alongside STP, but they operate independently, meaning their calculations don't interfere with each other. Rapid convergence in RSTP won't be utilized when STP is also in the network. Option B is incorrect as an STP-enabled switch cannot revert to RSTP mode after the RSTP-enabled switch is removed.
