Suggested answer: C

Explanation:

The attribute that must be selected to implement microsegmentation of endpoints within the same IP subnet using a network-based attribute that allows IP subnet independence is the Tag attribute. The Tag attribute is a user-defined attribute that can be assigned to endpoints based on any criteria, such as location, function, or security level. The Tag attribute can be used to create microsegmentation policies in ACI, which define the rules for communication between endpoints within the same or different bridge domains. The Tag attribute enables IP subnet independence, which means that the microsegmentation policies are not tied to the IP subnet of the endpoints, and can be applied across different subnets or even different fabrics. The Tag attribute also simplifies the management and scalability of microsegmentation policies, as it does not require the use of IP addresses or MAC addresses to identify endpoints.Reference:=
