An engineer must configure a service graph for the policy-based redirect to redirect traffic to a transparent firewall. The policy must be vendor-agnostic to support any firewall appliance. Which…

Setting Context Aware to Single is typically related to multi-context firewall deployments and does not directly address the requirements for vendor-agnosticism or transparent firewall operation.

Setting the Service Type to 'Other' ensures that the service graph is vendor-agnostic, as ACI does not expect a specific device package or managed device integration for the service appliance.

Setting Promiscuous Mode to True is a specific operational mode for devices like IDS/IPS that need to see all traffic on a segment, but it is not a primary configuration for vendor-agnostic PBR to a transparent firewall.

Setting the Function Type to 'L2' is essential for supporting a transparent firewall, as this indicates that the appliance operates at Layer 2 (bridging) and forwards frames based on MAC addresses rather than routing.

Setting Managed to True would require ACI APIC to manage the device via a device package, which contradicts the requirement for a vendor-agnostic appliance.
