Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 152

An engineer must configure OSPFv2 connectivity between a pair of Cisco Nexus switches. The connection between the switches must meet these requirements:
✑ Use unicast for updates.
✑ Use decentralized communication of updates.
✑ Full adjacency between switches.
Which configuration is needed to meet these requirements?

Answer options

• A. filter list between the neighbors
• B. stub area between the neighbors
• C. virtual link between the neighbors
• D. interface with a type of p2p network

Correct answer: C

Explanation

The correct answer is C, as a virtual link is necessary to establish full adjacency in OSPFv2 between non-contiguous OSPF areas. Option A is incorrect because a filter list would restrict updates rather than facilitate them. Option B is not suitable, as a stub area limits the type of routes that can be advertised, which does not align with the requirement for full adjacency. Option D, while establishing a point-to-point connection is relevant, does not specifically address the need for a virtual link to connect the switches effectively.
