JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2023) — Question 50

Which two statements describe aggregate routes? (Choose two.)

Answer options

• A. Invalid routing prefixes are not advertised to external peers.
• B. Internal routing instabilities can be hidden from external peers
• C. Groups of routes are combined into a single route entry.
• D. The route receives the next hop of the primary contributing route.

Correct answer: B, D

Explanation

Option B is correct because aggregate routes can indeed mask internal routing changes from external peers, enhancing stability. Option D is also correct as the aggregated route inherits the next hop attribute from the primary route contributing to the aggregate. Options A and C are incorrect because they do not accurately describe the behavior of aggregate routes; A refers to the behavior of routing protocols, while C misrepresents how routes are combined.
