Designing Cisco Data Center Infrastructure (DCID) — Question 114

An engineer is building a data center network with VXLAN EVPN. The requirement is to use multicast for the broadcast, unknown unicast, and multicast replication.

Which two VNI to multicast group mapping methods must be used to meet these requirements? (Choose two.)

Answer options

• A. many NVE to one multicast group
• B. one VNI to one multicast group
• C. many VNI to one multicast group
• D. one NVE to many multicast groups
• E. many VNI to many multicast groups

Correct answer: A, C

Explanation

The correct answers are A and C because both options allow for effective multicast group utilization by enabling either multiple Network Virtualization Edge (NVE) devices to share a single multicast group or multiple Virtual Network Identifiers (VNI) to be mapped to one multicast group. Options B, D, and E do not adequately support the requirement for multicast replication in the context specified.
