Google Professional Cloud DevOps Engineer Exam - 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?

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.

C sounds interesting, but does it really help with latency issues?

D? Really? That seems overkill for just performance issues.

I think B is more useful for catching errors, not performance.

I vaguely recall something about Prometheus being useful for monitoring, but I don't think it's specifically for tracing request performance like Cloud Trace.

I practiced a similar question where Cloud Profiler was mentioned. It might help with understanding resource usage, but I'm not convinced it's the best choice here.

I'm not entirely sure, but I think Error Reporting is more about catching exceptions rather than performance issues.

I remember studying about Cloud Trace and how it helps in tracking request latency. It seems like a good option for identifying slow dependencies.

I'm leaning towards option D, Google Cloud Managed Service for Prometheus. That could provide a comprehensive monitoring solution to help us understand the application's behavior and dependencies.

Configuring Cloud Profiler sounds like a good strategy to me. That should give us a detailed view of the application's performance and help pinpoint the problem areas.

Hmm, I'm a bit unsure about this one. I'm wondering if Error Reporting might be a better option to help identify the root cause of the performance issues.

I think the key here is to investigate the downstream dependencies, so I'd go with option A to configure Cloud Trace and get a better understanding of the application's performance.
