Question

Your company runs a real-time gaming service on Compute Engine instances in a single region. Clients connect over UDP to a public IP.

A regional external passthrough Network Load Balancer with a backend service and a TCP or HTTP health check on a separate serving port

A global external Application Load Balancer with a serverless NEG and a UDP health check
