JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2023) — Question 1
Which three link-specific fields must match between OSPF neighbors before they form an adjacency over a broadcast medium? (Choose three.)
Answer options
- A. dead interval
- B. options
- C. hello interval
- D. neighbor
- E. router priority
Correct answer: A, C, D
Explanation
The correct parameters for OSPF neighbor adjacency are dead interval, hello interval, and neighbor. The dead interval determines how long a router waits before declaring a neighbor down, the hello interval is how often hello packets are sent, and the neighbor must be the same for adjacency. The options and router priority do not need to match for an OSPF adjacency to be formed.
