Google Cloud Professional Cloud Network Engineer — Question 148

You are in the process of deploying an internal HTTP(S) load balancer for your web server virtual machine (VM) instances. What two prerequisite tasks must be completed before creating the load balancer? (Choose two.)

Answer options

• A. Choose a region.
• B. Create firewall rules for health checks.
• C. Reserve a static IP address for the load balancer.
• D. Determine the subnet mask for a proxy-only subnet.
• E. Determine the subnet mask for Serverless VPC Access.

Correct answer: B, D

Explanation

The correct answers are B and D because creating firewall rules for health checks ensures that the load balancer can verify the health of the backend instances, while determining the subnet mask for a proxy-only subnet is crucial for proper network configuration. Options A and C, while relevant, are not prerequisites specifically required for the load balancer setup, and option E is unrelated to the internal HTTP(S) load balancer configuration.
