Which statement about policy based redirect In an ACI fabric is true?

PBR's primary function is traffic redirection to service devices, not placing unmanaged nodes in separate VRFs.

ACI's PBR policies are defined through contracts and policy configurations that match traffic criteria, rather than directly relying on traditional access lists for redirection.

PBR can be deployed with both managed (using device packages) and unmanaged Layer 4-7 devices, meaning a device package is not a strict requirement for all PBR implementations.

PBR provides the flexibility to redirect traffic through a Layer 4-7 service device without requiring the consumer and provider EPGs to be in different VRFs or subnets. This simplifies service chain deployment by allowing traffic to be steered to a service appliance regardless of its logical network location relative to the EPGs involved.
