JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2024) — Question 1

Which two statements are correct regarding the root bridge election process when using STP? (Choose two.)

Answer options

• A. A lower system MAC address is preferred.
• B. A higher bridge priority is preferred.
• C. A lower bridge priority is preferred.
• D. A higher system MAC address is preferred.

Correct answer: A, C

Explanation

The root bridge election process in STP prioritizes lower bridge priorities, which means that statement C is correct. Additionally, if bridge priorities are identical, the system with the lower MAC address is chosen, making statement A also correct. Statements B and D are incorrect because higher bridge priorities and MAC addresses do not contribute to a successful election.
