Which endpoint learning operation is completed on the ingress leaf switch when traffic is received from a Layer 3 Out?
A. The source MAC address of the traffic is learned as a local endpoint.
B. The source MAC address of the traffic is learned as a remote endpoint.
C. The source IP address of the traffic is learned as a remote endpoint.
D. The source IP address of the traffic is learned as a local endpoint.
Correct answer should be C. The question states “Layer 3 Out”, so we are talking IP addresses here not MAC addresses. Also, it would be learned as a remote endpoint since L3 OUT.

AK is right. Answer is A.
Leaf switches learn only the MAC because it would not be able to hold all of the possible IP addresses learned from an L3Out. So it only learns the MAC of the L3Out. It would also be a local endpoint on the ingress switch because it learned it on an access port and not from the fabric port (which would be remote endpoint).
