正解:A
Static ingress replication is a method used in VXLAN environments where the replication of multicast, broadcast, and unknown unicast traffic is manually defined. In the context of Cisco Data Center Core Technologies, Option A implements static ingress replication by explicitly specifying peers for replication using the ingress-replication protocol static command followed by the peer-ip command to define the IP address of the replication peer. This configuration is necessary when multicast routing is not an option in the underlay network.
References := For further details, one would typically refer to Cisco's official documentation on VXLAN configurations and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) study materials, which provide in-depth explanations on the setup and management of network overlays including static ingress replication.
