H12-821_V1.0 Question #582: Real Exam Question with Answer & Explanation
The correct answer is A. In this broadcast network, R1 and R2 use a three-way handshake to establish an adjacency relationship B. In the broadcast network, the DIS needs to be elected. After the adjacency relationship is established, the router will wait for the interval between two Hello packets and send the next Hello C. R2 marks the adjacency state as Initial after receiving the IIH message sent by R1. Then, R2 replies to R1 with Level-1LANIIH, which identifies R1 as the adjacency of R2. See the full explanation below for the reasoning.
