Answer: A B
Explanation
When OSPF sends an advertisement to an adjacent router, it expects to receive an acknowledgment from that neighbor. If no acknowledgment is received, the router will retransmit the advertisement to its neighbor. The retransmit-interval timer controls the number of seconds between retransmissions. To edit the retransmit-interval, use the “ip ospf retransmit-interval seconds” in interface configuration mode -> A is correct.
Dead-interval is the number of seconds without hello packets before an adjacency is declared down. To edit the dead-interval, use the “ip ospf dead-interval seconds” in interface configuration mode -> B is correct.
Other answers are not correct because they are not interface parameters.
