Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 443

The Gig0/0 interface of two routers is directly connected with a 1G Ethernet link. Which configuration must be applied to the interface of both routers to establish an OSPF adjacency without maintaining a DR/BDR relationship?

Answer options

• A. interface Gig0/0 ip ospf network non-broadcast
• B. interface Gig0/0 ip ospf network point-to-multipoint
• C. interface Gig0/0 ip ospf network point-to-point
• D. interface Gig0/0 ip ospf network broadcast

Correct answer: C

Explanation

The correct answer is C, as configuring the interface for point-to-point OSPF operation allows direct OSPF adjacency without a DR/BDR setup. Options A and B are incorrect because they do not fit the requirements for a direct connection, and option D is not suitable since it establishes a broadcast network type, which would require a DR/BDR relationship.
