You are deploying a regional Internal Application Load Balancer in a Google Cloud VPC network to distribute HTTP traffic across Compute Engine backend instances. Which TWO networking prerequisites or configurations are required for the load balancer to operate properly? (Select TWO.)
- Create a proxy-only subnet in the region where the load balancer is being deployed.Answer
- Configure ingress firewall rules to allow traffic from the proxy-only subnet CIDR range to the backend instances.Answer
- CAssign a global external static IP address to the load balancer forwarding rule.
- DEnable the Cloud DNS API at the GCP Organization resource level.
Answer
Creating a proxy-only subnet in the deployment region and configuring ingress firewall rules to permit traffic from the proxy-only subnet range to the backend instances are required.
Regional Internal Application Load Balancers deploy Envoy proxies that operate inside a dedicated proxy-only subnet in the region. In addition, ingress firewall rules must be created to allow traffic from the proxy-only subnet IP address range to reach the application ports on the backend VM instances.
