JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing (2023) — Question 25

What is a key differentiator of generate routes from aggregate routes?

Answer options

• A. Generate routes cannot be used as a gateway of last resort.
• B. Generate routes use a forwarding next hop.
• C. Generate routes have a default next-hop value of reject.
• D. Generate routes have a default preference value of 210.

Correct answer: B

Explanation

The correct answer is B because generate routes specifically rely on a forwarding next hop to direct traffic. Option A is incorrect since generate routes can serve as a gateway of last resort if configured properly. Option C is misleading as aggregate routes typically have a different default next-hop value, and D is inaccurate because the default preference for generate routes is not fixed at 210.
