You support a Node.js application running on Google Kubernetes Engine (GKE) in production. The application makes several HTTP requests to dependent applications. You want to anticipate which dependent applications might cause performance issues. What should you do?

  • A. Instrument all applications with Stackdriver Profiler.
  • B. Instrument all applications with Stackdriver Trace and review inter-service HTTP requests.
  • C. Use Stackdriver Debugger to review the execution of logic within each application to instrument all applications.
  • D. Modify the Node.js application to log HTTP request and response times to dependent applications. Use Stackdriver Logging to find dependent applications that are performing poorly.

Answer is B. The keyword is "make several requests to dependent app". So you need trace for it. Cloud Trace Find performance bottlenecks in production. Cloud Profiler Continuous CPU and heap profiling to improve performance and reduce costs.

Selected Answer: B
B. Instrument all applications with Stackdriver Trace and review inter-service HTTP requests. Stackdriver Trace allows you to collect and analyze performance data for all the applications that make up your system, including the applications running on GKE. By instrumenting your application with Stackdriver Trace, you can see detailed performance information for each request, including the time spent in each component of your system, as well as any inter-service HTTP requests. This will allow you to identify which dependent applications might be causing performance issues, so that you can focus on optimizing those services specifically.

B is the answer. https://cloud.google.com/trace/docs/overview Cloud Trace, a distributed tracing system for Google Cloud, helps you understand how long it takes your application to handle incoming requests from users or other applications, and how long it takes to complete operations like RPC calls performed when handling the requests.

You need to define Service Level Objectives (SLOs) for a high-traffic multi-region web application. Customers expect the application to always be available and have fast response times. Customers are currently happy with the application performance and availability. Based on current measurement, you observe that the 90th percentile of latency is 120ms and the 95th percentile of latency is 275ms over a 28-day window. What latency SLO would you recommend to the team to publish? A. 90th percentile - 100ms 95th percentile - 250ms B. 90th percentile - 120ms 95th percentile - 275ms C. 90th percentile - 150ms 95th percentile - 300ms D. 90th percentile - 250ms 95th percentile - 400ms

For selecting SLO target i will select C ( because D it is a too relexed for a SLA), but I'm not sure B could also be a good choice if you want a more challenging SLO
