Refer to the exhibit. A load balancer is connected to the Cisco ACI fabric using a single interface. The load balancer is performing source and destination NAT. A service graph is configured on the Cisco ACI. Which action must be taken to allow traffic from host A to pass through the load balancer before reaching host B?
To ensure that the traffic from host A passes through the load balancer before reaching host B, policy-based routing (PBR) should be applied on the contract between the load balancer and the application EPGs. This would direct the traffic from the source endpoint group (EPG) to the destination EPG through the load balancer, allowing it to perform source and destination NAT as required.
A is the correct answer. https://www.cisco.com/c/en/us/solutions/collateral/data-center-virtualization/application-centric-infrastructure/white-paper-c11-739971.html

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.
