JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2023) — Question 44

An OSPF hello packet has been sent, but bidirectional communication has not been established. What is the state of the OSPF adjacency?

Answer options

• A. Down
• B. Init
• C. Exchange
• D. Loading

Correct answer: A

Explanation

The OSPF adjacency state is 'Down' when no bidirectional communication has been established after sending a hello packet. The 'Init' state indicates that a hello packet was received but not reciprocated, while 'Exchange' and 'Loading' states occur only after the adjacency has been established successfully.
