Huawei Certified Network Professional – Routing and Switching (HCNP-RS, legacy) — Question 6

Which of the following statements about a neighbor state machine is true?

Answer options

• A. The Attempt state appears only on an NBMA network or a broadcast network.
• B. The Attempt state appears only on an NBMA network or a P2MP network.
• C. LSR packets can be sent in the Exchange state.
• D. The Full state indicates that LSDB synchronization is complete. No LSDB information will be exchanged.

Correct answer: C

Explanation

The correct answer is C because LSR packets are indeed exchanged during the Exchange state, facilitating the synchronization of link-state databases. Options A and B are incorrect as they misrepresent the networks where the Attempt state is applicable. Option D is also incorrect since the Full state indicates that LSDB synchronization is complete, but it does not mean that no LSDB information will be exchanged.
