Google Cloud Professional Cloud Database Engineer — Question 101

Your retail organization is preparing for the holiday season. Use of catalog services is increasing, and your DevOps team is supporting the Cloud SQL databases that power a microservices-based application. The DevOps team has added instrumentation through Sqlcommenter. You need to identify the root cause of why certain microservice calls are failing. What should you do?

Answer options

• A. Watch Query Insights for long running queries.
• B. Watch the Cloud SQL instance monitor for CPU utilization metrics.
• C. Watch the Cloud SQL recommenders for overprovisioned instances.
• D. Watch Cloud Trace for application requests that are failing.

Correct answer: D

Explanation

The correct answer is D because Cloud Trace allows you to view detailed traces of application requests, which can help identify the specific requests that are failing. Options A and B focus on performance metrics without directly addressing the failures, while option C is about resource optimization rather than diagnosing issues.
