correctly learns the remote endpoint MAC. Which information must be included in the
VXLAN packet that is received from the Cisco ACI spine for the Cisco ACI leaf to learn
MAC as a remote endpoint?

As part of a newly deployed ACI fabric, a pair of border leaf switches have been deployed
to provide shared services for all tenants. The configured L3Out runs OSPF as the routing
protocol. The requirement is to advertise the routes from the border leaf switches to the
compute leaf switches. Which configuration must be implemented to meet these
requirements?
A.
Configure a BGP route reflector policy for the Cisco ACI pod
B.
Define the shared L3Out in the common tenant
C.
Enable Import Route Control Enforcement in the L3Out policy
D.
Define the consumer subnet under the consumer EPG
Configure a BGP route reflector policy for the Cisco ACI pod

How is the ARP request from VM1 forwarded when VM2 is not learned in the Cisco ACI
fabric?
A.
Leaf 101 forwards the ARP request to one of the proxy VTEP spines.
B.
POD1 spine responds to the ARP request after the POD1 COOP is updated with the VM2 location.
C.
Leaf 101 encapsulates the ARP request into a multicast packet that is destined to 225.0.37.192.
D.
Leaf 101 switch consumes the ARP reply of VM2 to update the local endpoint table
Leaf 101 forwards the ARP request to one of the proxy VTEP spines.
