You are managing an application that runs in Compute Engine. The application uses a custom HTTP server to expose an API that is accessed by other applications through an internal TCP/UDP load balancer. A firewall rule allows access to the API port from 0.0.0.0/0. You need to configure Cloud Logging to log each IP address that accesses the API by using the fewest number of steps. What should you do first?
- A.Enable Packet Mirroring on the VPC.
- B.Install the Ops Agent on the Compute Engine instances.
- C.Enable logging on the firewall rule.
- D.Enable VPC Flow Logs on the subnet.
