Question

Refer to the exhibit. A network engineer configures a Layer 4 to Layer 7 device for an outside routed firewall that is connected to POD-1 inside a Cisco ACI fabric that consists of two pods. All traffic from POD-1 or POD-2 that uses the L3Out should pass through the routed firewall. Which Function Type must be implemented in the service graph for POD-2 to use L3Out?

Explanation

In a Cisco ACI fabric, when configuring a Layer 4 to Layer 7 device for routing traffic through an external firewall connected to the inside of the fabric, the appropriate Function Type in the service graph must be selected to ensure that traffic from both POD-1 and POD-2 passes through the routed firewall when using L3Out. The "GoTo" Function Type is used in scenarios where all traffic destined for L3Out needs to be redirected through a service node like a firewall. This ensures that regardless of the source pod, traffic will traverse the service node before exiting the fabric.
