Selected Answer: A

In Cisco ACI, when a load balancer is performing source and destination NAT and is connected to the fabric using a single interface, traffic must be explicitly redirected through the load balancer for both inbound and outbound flows. This ensures that the load balancer processes traffic in both directions, maintaining consistent NAT mappings. To achieve this, Policy-Based Redirect (PBR) must be applied on the contract between the consumer EPG (host A) and provider EPG (host B). PBR ensures that traffic is redirected to the load balancer before reaching its destination.
