JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing (2022) — Question 22

Which statement about a virtual-router type of routing instance is correct?

Answer options

• A. It is used to separate large networks into smaller administrative entities
• B. It is the only routing instance type supported on Junos devices
• C. It is used in Layer 3 VPN implementations
• D. It is used to create and maintain separate routing and forwarding tables

Correct answer: D

Explanation

The correct answer is D because a virtual-router creates separate routing and forwarding tables, allowing for independent routing processes. Option A is incorrect as it pertains more to administrative domains than to the specific function of a virtual-router. Option B is false because Junos supports multiple routing instance types, and option C, while related to VPNs, does not describe the primary function of a virtual-router.
