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. B. C. D.D.
In an ACI fabric, microsegmentation is a method of dividing a network into smaller, isolated segments to improve security and simplify network management. Microsegmentation can be achieved through the use of network-based attributes, which are assigned to endpoints and used to enforce policies.
To implement microsegmentation of endpoints within the same IP subnet using a network-based attribute, the attribute selected must be independent of the IP subnet. This means that the attribute should not change if an endpoint is moved to a different IP subnet or if the IP subnet is reconfigured.
Out of the options given, the attribute that best meets this requirement is a "tag". A tag is a network-based attribute that can be assigned to endpoints and is independent of the IP subnet. Tags can be used to classify endpoints based on a variety of criteria, such as application type, user group, or location. By using tags to group endpoints, policies can be applied to specific groups of endpoints regardless of their IP subnet.
Therefore, the correct answer to the question is B. tag.
