Huawei Certified ICT Associate – Data Center Network (HCIA-DCN) — Question 11

In STP, which of the following items may affect the selection of the root switch? (Choose two.)

Answer options

• A. Switch priority.
• B. Switch port ID.
• C. Switch interface bandwidth.
• D. Switch MAC address.
• E. Switch IP address.

Correct answer: A, D

Explanation

The switch MAC address is used as a tiebreaker when multiple switches have the same priority, while the other options do not play a role in the root switch selection.
