JNCIP-DC: Juniper Networks Certified Professional – Data Center (2023) — Question 1

You are asked to configure your IP fabric with OSPF as the underlay routing protocol.
Which two statements are correct about this implementation? (Choose two.)

Answer options

• A. Each host-connected interface of the leaf node is included as passive in the OSPF configuration.
• B. Each host-connected interface of the leaf node is included in the OSPF configuration.
• C. Each spine-connected interface of the leaf node is included as passive in the OSPF configuration.
• D. Each spine-connected interface of the leaf node is included in the OSPF configuration.

Correct answer: A, D

Explanation

Option A is correct because host-connected interfaces should be passive to prevent them from forming OSPF adjacencies. Option D is also correct as spine-connected interfaces need to participate in the OSPF routing process. Options B and C are incorrect because host-connected interfaces should not be included actively in OSPF, and the spine-connected interfaces are not passive.
