Huawei Certified ICT Associate – Data Center Network (HCIA-DCN) — Question 25

Which of the following OSPF states can be used to indicate that an adjacency relationship has been established?

Answer options

• A. Down
• B. 2-way
• C. Full
• D. Attempt

Correct answer: C

Explanation

The 'Full' state indicates that the routers have completed the OSPF adjacency process and are exchanging routing information. The 'Down' state means there is no communication, '2-way' indicates that a basic level of communication exists but is not yet fully established, and 'Attempt' is used in a point-to-multipoint network, which does not signify a fully established adjacency.
