JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2024) — Question 59

What are two methods for reducing the size of an OSPF link-state database? (Choose two.)

Answer options

• A. Use unique router IDs where possible.
• B. Use identical link metrics where possible.
• C. Use point-to-point interface types where possible.
• D. Use stub areas where possible.

Correct answer: C, D

Explanation

Using point-to-point interface types helps streamline OSPF routing by reducing the number of adjacencies, thus minimizing the link-state database size. Stub areas further reduce the database by preventing external routes from being advertised, allowing for a smaller and more manageable OSPF database. The other options, while beneficial in other contexts, do not directly contribute to reducing the size of the OSPF link-state database.
