Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 420

An engineer must implement a VXLAN-based data center interconnect. The long-distance transport provided by a service provider is IP-based, supports a maximum MTU of 1554 bytes, and does not support outbound traffic replication. Which action must be taken to build the data center interconnect?

Answer options

• A. Announce host reachability over BGP.
• B. Create an IP access list and associate it with VNI to replicate traffic to remote VTEPs.
• C. Configure a route map to associate the IPs of the remote VTEPs.
• D. Implement BGP EVPN ingress replication.

Correct answer: D

Explanation

The correct answer is D because BGP EVPN ingress replication allows for efficient traffic forwarding in VXLAN environments without the need for outbound traffic replication, which is not supported in this scenario. The other options do not address the requirement for ingress replication or involve methods that are not compatible with the given constraints, such as outbound traffic replication or configurations that are unnecessary for the task.
