Which two routing interface parameters are supported in OSPF implementations? (Choose
two.)

A.
retransmit-interval

B.
dead-interval

C.
stub area

D.
virtual link

E.
NSSA area

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.
