JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 59

What are two reasons for creating multiple areas in OSPF? (Choose two.)

Answer options

• A. to reduce the convergence time
• B. to increase the number of adjacencies in the backbone
• C. to increase the size of the LSDB
• D. to reduce LSA flooding across the network

Correct answer: A, D

Explanation

Creating multiple areas in OSPF helps to reduce the convergence time by limiting the scope of route changes to smaller areas. Additionally, it minimizes LSA flooding, preventing excessive route advertisements across the entire network, thus enhancing overall efficiency. The other options, such as increasing the number of adjacencies or the size of the LSDB, do not align with the primary goals of area segmentation.
