Refer to the exhibit. Which two configurations enable R1 and R2 to advertise routes into OSPF? (Choose two.)
Refer to the exhibit. Which two configurations enable R1 and R2 to advertise routes into OSPF? (Choose two.)
In OSPF configurations, wildcard masks are used instead of subnet masks for defining which interfaces belong to which OSPF area. Option A correctly uses wildcard masks (0.0.0.255) for the networks on R2. Similarly, option D correctly uses wildcard masks (0.0.0.255) for the networks on R1. Therefore, the correct configurations to enable R1 and R2 to advertise routes into OSPF are A and D.
OSPF uses wildcard mask, NOT subnet mask. So the correct answers are AD.
A and D are correct
Btw, There is no OSPF process ID 0. OSPF process ID starts from 1. "router ospf 0" in the options must be typo.
A & D are correct
Simple, in answers B,C & E, a network mask is used instead of a wildcard mask. A & D are remaining.
