Google Cloud Professional Cloud Database Engineer — Question 44

You recently launched a new product to the US market. You currently have two Bigtable clusters in one US region to serve all the traffic. Your marketing team is planning an immediate expansion to APAC. You need to roll out the regional expansion while implementing high availability according to Google-recommended practices. What should you do?

Answer options

• A. Maintain a target of 23% CPU utilization by locating: cluster-a in zone us-central1-a cluster-b in zone europe-west1-d cluster-c in zone asia-east1-b
• B. Maintain a target of 23% CPU utilization by locating: cluster-a in zone us-central1-a cluster-b in zone us-central1-b cluster-c in zone us-east1-a
• C. Maintain a target of 35% CPU utilization by locating: cluster-a in zone us-central1-a cluster-b in zone australia-southeast1-a cluster-c in zone europe-west1-d cluster-d in zone asia-east1-b
• D. Maintain a target of 35% CPU utilization by locating: cluster-a in zone us-central1-a cluster-b in zone us-central2-a cluster-c in zone asia-northeast1-b cluster-d in zone asia-east1-b

Correct answer: D

Explanation

The correct answer, D, maintains a target of 35% CPU utilization and distributes the clusters across multiple zones in the APAC region, ensuring high availability. Options A and B have a lower CPU utilization target and do not effectively spread the clusters across different regions. Option C, while maintaining CPU utilization, does not strategically place clusters in a way that optimizes availability across the APAC region.
