JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 51

Two routers share the same highest priority and start time.
In this situation, what is evaluated next when determining the designated router?

Answer options

• A. The router with the lowest router ID become the DR.
• B. The router with the highest router ID becomes the DR.
• C. The routers perform another DR election.
• D. The router with the highest MAC address become the DR.

Correct answer: B

Explanation

In the event that two routers have the same priority and start time, the tie is broken by comparing their router IDs. The router with the highest router ID is designated as the DR. The other options do not apply as they either suggest an incorrect ID evaluation or an unnecessary re-election.
