JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 34

On EX Series devices, what are two software features that accommodate redundancy? (Choose two.)

Answer options

• A. OAM
• B. NSR
• C. IGMP
• D. GRES

Correct answer: B, D

Explanation

NSR (Non-Stop Routing) and GRES (Graceful Routing Engine Switchover) are both designed to maintain service continuity during failover events, making them essential for redundancy. OAM (Operations, Administration, and Maintenance) and IGMP (Internet Group Management Protocol) do not specifically address redundancy in the same manner.
