Dynamic EPG Assignment

D.

The feature that dynamically assigns or modifies the EPG (End Point Group) association of virtual machines based on their attributes is the uSeg (User Segment) EPG.

In Cisco Application Centric Infrastructure (ACI), the EPG is a logical grouping of endpoints that share common network and security policies. Endpoints can be physical servers, virtual machines, or other network devices. EPGs are used to define policies for communication between endpoints within the same group or across different groups.

The uSeg EPG is a special type of EPG that dynamically assigns or modifies EPG associations based on the attributes of endpoints. This allows endpoints to be dynamically classified and grouped based on their characteristics, such as operating system type, application type, or security posture.

When an endpoint connects to the ACI fabric, its attributes are analyzed to determine the appropriate uSeg EPG. The uSeg EPG then assigns the endpoint to the appropriate application EPG, which contains the necessary network and security policies for that endpoint.

The other answer options, vzAny contracts and standard contracts, are not related to dynamically assigning or modifying EPG associations based on endpoint attributes. VzAny contracts are used to define policies that can be applied to any EPG, while standard contracts are predefined contracts that can be used between EPGs. Application EPGs are used to group endpoints that belong to the same application or service.
