You have an application running in Google Kubernetes Engine. The application invokes multiple services per request but responds too slowly. You need to identify which downstream service or services are causing the delay. What should you do?

1. A. Analyze VPC flow logs along the path of the request.
2. B. Investigate the Liveness and Readiness probes for each service.
3. C. Create a Dataflow pipeline to analyze service metrics in real time.
4. D. Use a distributed tracing framework such as OpenTelemetry or Stackdriver Trace.

Correct Answer: C

You support a high-traffic web application with a microservice architecture. The home page of the application displays multiple widgets containing content such as the current weather, stock prices, and news headlines. The main serving thread makes a call to a dedicated microservice for each widget and then lays out the homepage for the user. The microservices occasionally fail; when that happens, the serving thread serves the homepage with some missing content. Users of the application are unhappy if this degraded mode occurs too frequently, but they would rather have some content served instead of no content at all. You want to set a Service Level Objective (SLO) to ensure that the user experience does not degrade too much. What Service Level Indicator {SLI) should you use to measure this?

1. A. A quality SLI: the ratio of non-degraded responses to total responses
2. B. An availability SLI: the ratio of healthy microservices to the total number of microservices
3. C. A freshness SLI: the proportion of widgets that have been updated within the last 10 minutes
4. D. A latency SLI: the ratio of microservice calls that complete in under 100 ms to the total number of microservice calls

Your company experiences bugs, outages, and slowness in its production systems. Developers use the production environment for new feature development and bug fixes. Configuration and experiments are done in the production environment, causing outages for users. Testers use the production environment for load testing, which often slows the production systems. You need to redesign the environment to reduce the number of bugs and outages in production and to enable testers to load test new features. What should you do?

1. A. Create an automated testing script in production to detect failures as soon as they occur.
2. B. Create a development environment with smaller server capacity and give access only to developers and testers.
3. C. Secure the production environment to ensure that developers can't change it and set up one controlled update per year.
4. D. Create a development environment for writing code and a test environment for configurations, experiments, and load testing.

Correct Answer: D
