JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 89

What are two purposes of an aggregate route? (Choose two.)

Answer options

• A. to allow external peers to see internal routes
• B. to hide internal routes from external peers
• C. to increase the number of route advertisements
• D. to decrease the number of route advertisements

Correct answer: B, D

Explanation

The correct answers are B and D because an aggregate route is used to hide internal routing information from external peers, thereby enhancing security and efficiency. Additionally, it decreases the number of route advertisements by summarizing multiple routes into one, which helps to reduce the size of the routing table. Options A and C are incorrect as they do not align with the primary purposes of aggregate routes.
