[All Professional Cloud DevOps Engineer Questions]

Your application's performance in Google Cloud has degraded since the last release. You suspect that downstream dependencies might be causing some requests to take longer to complete. You need to investigate the issue with your application to determine the cause. What should you do?

AConfigure Cloud Trace in your application.

BConfigure Error Reporting in your application.

CConfigure Cloud Profiler in your application.

DConfigure Google Cloud Managed Service for Prometheus in your application.

Show Suggested Answer

Suggested Answer: A

Comprehensive and Detailed

Google Cloud Trace is specifically designed to analyze request latency and identify performance bottlenecks across services. Since the issue is related to slow performance after a new release, the best approach is to use Cloud Trace to:

Visualize request latency across services

Pinpoint slow dependencies affecting response time

Analyze performance trends over time

Why not other options?

B (Error Reporting) Focuses on uncaught exceptions and crashes, not latency issues.

C (Cloud Profiler) Helps with CPU and memory analysis, not request tracing.

D (Prometheus for Cloud Monitoring) Useful for metrics collection, but not ideal for debugging specific request latency issues.

Option B is the best choice here. Error Reporting will give you the juicy details on what's going wrong with your app. Plus, it's like having a personal therapist for your application.

I believe Error Reporting could also be useful to track any errors that are impacting performance.

Nah, I'd go with option A. Cloud Trace is like a crystal ball for your app's performance issues. You can see exactly where the slowdowns are happening.
