Exam Professional Cloud Network Engineer topic 1 question 160 discussion

A - When you create an internal HTTP(S) load balancer, you must choose a specific region where the load balancer and its associated resources (like backend services and VM instances) will be deployed. B - The internal HTTP(S) load balancer needs to perform health checks on the backend VM instances to determine their availability and health.

B - create health checks D - need proxy subnet , so determine the unused subnet mask

I think is can be A & B B is obvious.... However you don't configure the subnet mask separately from the subnet for the proxy-only subnet. You do need to choose the region of deployment

B&D is correct

B&D is right.

A) No: The region must match that of your application instances, so there is no choice to be made. B) Yes: FW rules are needed for the healthchecks (and also for the proxies) C) No: Reserving a static IP for the LB is an optional step, not a prerequisite D) Yes: A proxy-only subnet reservation is necessary for the Internal HTTP Load Balancer E) No: Serverless VPC Access is not relevant to this question https://cloud.google.com/load-balancing/docs/l7-internal/setting-up-l7-internal#configure-a-network

The two prerequisite tasks that must be completed before creating an internal HTTP(S) load balancer are to choose a region and to determine the subnet mask for a proxy-only subnet.
