Which two routing interface parameters are supported in OSPF implementations? (Choose two.)
Correct Answer: A,B
Explanation/Reference:
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.
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.
Other answers are not correct because they are not interface parameters.
