JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 33

Which statement describes GRES?

Answer options

• A. GRES requires NSR to function properly.
• B. GRES provides routing loop protection.
• C. GRES provides hardware-level high availability.
• D. GRES rapidly detects link failures.

Correct answer: A

Explanation

The correct answer is A because GRES (Graceful Restart) indeed relies on NSR (Non-Stop Routing) to operate effectively. The other options do not accurately describe GRES, as it does not specifically provide routing loop protection, hardware-level high availability, or rapid link failure detection.
