JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing (2021) — Question 35

Which two statements are true about NSR? (Choose two.)

Answer options

• A. NSR requires graceful restart to function properly
• B. NSR requires redundant REs.
• C. NSR requires only one RE.
• D. NSR requires GRES to function properly.

Correct answer: B, D

Explanation

The correct answers are B and D because NSR indeed requires redundant Routing Engines (REs) to ensure high availability and requires GRES (Graceful Restart) to function properly. Option A is incorrect since NSR does not rely on graceful restart alone, and option C is wrong because NSR specifically needs multiple REs for redundancy.
