Google Cloud Professional Cloud Database Engineer — Question 96

Your organization stores marketing data such as customer preferences and purchase history on Bigtable. The consumers of this database are predominantly data analysts and operations users. You receive a service ticket from the database operations department citing poor database performance between 9 AM-10 AM every day. The application team has confirmed no latency from their logs. A new cohort of pilot users that is testing a dataset loaded from a third-party data provider is experiencing poor database performance. Other users are not affected. You need to troubleshoot the issue. What should you do?

Answer options

• A. Isolate the data analysts and operations user groups to use different Bigtable instances.
• B. Check the Cloud Monitoring table/bytes_used metric from Bigtable.
• C. Use Key Visualizer for Bigtable.
• D. Add more nodes to the Bigtable cluster.

Correct answer: C

Explanation

Using Key Visualizer for Bigtable allows you to analyze the performance and access patterns of the data, which is crucial for identifying issues related to the new cohort of pilot users. The other options, such as isolating user groups or checking metrics, may not directly address the specific performance problems being experienced by the new users testing the dataset.
