Google Professional Cloud DevOps Engineer Question 164
Select 3Google Cloud PlatformYour team has deployed a new microservices-based application on Google Kubernetes Engine (GKE). To monitor performance and troubleshoot issues, you need to instrument the application to provide detailed metrics and traces. Which of the following steps should you take to implement effective application instrumentation?
- A
Integrate OpenTelemetry SDK into the application code to capture distributed traces and metrics.
- B
Enable Binary Authorization to enforce security policies during application deployment.
- C
Use Google Cloud's Operations Suite (formerly Stackdriver) to export application logs and traces.
- D
Modify the application code to include custom logging for critical business operations.
- E
Install the Kubernetes Horizontal Pod Autoscaler (HPA) to manage application scaling based on CPU and memory usage.
Show answer and explanation
Correct answers: A, C, D
Explanation
Effective application instrumentation involves capturing metrics, traces, and logs to monitor the application's performance and troubleshoot issues. OpenTelemetry SDK enables distributed tracing and metrics collection. Google Cloud's Operations Suite helps export and analyze these traces, logs, and metrics. Additionally, custom logging ensures critical business events are recorded. Binary Authorization and HPA are valuable for security and scaling but do not contribute to application instrumentation.
- A. Correct.
This is correct. OpenTelemetry is a widely adopted open-source framework for capturing distributed traces and metrics in modern applications.
- B. Incorrect.
This is incorrect. Binary Authorization is a security feature to enforce deployment policies; it is unrelated to application instrumentation.
- C. Correct.
This is correct. Google Cloud's Operations Suite can be used to export and analyze logs, metrics, and traces to monitor application health effectively.
- D. Correct.
This is correct. Custom logging is a key step in application instrumentation to capture critical events or business-specific information.
- E. Incorrect.
This is incorrect. While HPA is valuable for managing resource scaling, it does not relate to application instrumentation for metrics or traces.
