Google Cloud Professional Cloud Security Engineer — Question 236

Your company operates an application instance group that is currently deployed behind a Google Cloud load balancer in us-central-1 and is configured to use the
Standard Tier network. The infrastructure team wants to expand to a second Google Cloud region, us-east-2. You need to set up a single external IP address to distribute new requests to the instance groups in both regions.
What should you do?

Answer options

• A. Change the load balancer backend configuration to use network endpoint groups instead of instance groups.
• B. Change the load balancer frontend configuration to use the Premium Tier network, and add the new instance group.
• C. Create a new load balancer in us-east-2 using the Standard Tier network, and assign a static external IP address.
• D. Create a Cloud VPN connection between the two regions, and enable Google Private Access.

Correct answer: B

Explanation

The correct answer is B because changing the load balancer frontend to use the Premium Tier allows for global load balancing, which is necessary for routing traffic across regions. Options A and C do not provide a solution for using a single external IP across multiple regions, and option D is unrelated to the requirement of managing external IP addresses for load balancing.
