An engineer implements an ACI fabric and must implement microsegmentation of endpoints within the same IP subnet using a network-based attribute. The attribute mapping must allow IP subnet independence. Which attribute must be selected?

A. IP

B. tag

C. custom

D. MAC address








 

Suggested Answer: D

If you want to use a network-based attribute and classify IP addresses in the same subnet, you must use the MAC-based network attribute. IP-based microsegmented EPGs do not support classification for IP addresses in the same subnet. IP-based microsegmented EPGs are supported only when traffic requires Layer 3 routing. If the traffic is bridged, the microsegmentation policy cannot be enforced.
