Google Exam Professional Cloud DevOps Engineer Topic 3 Question 89 Discussion

Actual exam question for Google's Professional Cloud DevOps Engineer exam
Question #: 89
Topic #: 3
[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?

Show Suggested Answer Hide 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.

Dude, option D is where it's at! Managed Service for Prometheus is like having a personal genie for your monitoring needs.

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.
