You are ready to deploy a new feature of a web-based application to production. You want to use Google Kubernetes Engine (GKE) to perform a phased rollout to half of the web server pods.
What should you do?

  1. Use a partitioned rolling update.
  2. Use Node taints with NoExecute.
  3. Use a replica set in the deployment specification.
  4. Use a stateful set with parallel pod management policy.

Answer(s): A

You are responsible for the reliability of a high-volume enterprise application. A large number of users report that an important subset of the application's functionality ­ a data intensive reporting feature ­ is consistently failing with an HTTP 500 error.
When you investigate your application's dashboards, you notice a strong correlation between the failures and a metric that represents the size of an internal queue used for generating reports. You trace the failures to a reporting backend that is experiencing high I/O wait times. You quickly fix the issue by resizing the backend's persistent disk (PD). How you need to create an availability Service Level Indicator (SLI) for the report generation feature. How would you define it?

  1. As the I/O wait times aggregated across all report generation backends
  2. As the proportion of report generation requests that result in a successful response
  3. As the application's report generation queue size compared to a known-good threshold
  4. As the reporting backend PD throughout capacity compared to a known-good threshold

Answer(s): B

Explanation:

According to SRE Workbook, one of potential SLI is as below:
* Type of service: Request-driven
* Type of SLI: Availability
* Description: The proportion of requests that resulted in a successful response.

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

Answer(s): C



You are creating and assigning action items in a postmodern for an outage. The outage is over, but you need to address the root causes. You want to ensure that your team handles the action items quickly and efficiently. How should you assign owners and collaborators to action items?

  1. Assign one owner for each action item and any necessary collaborators.
  2. Assign multiple owners for each item to guarantee that the team addresses items quickly
  3. Assign collaborators but no individual owners to the items to keep the postmortem blameless.
  4. Assign the team lead as the owner for all action items because they are in charge of the SRE team.

Answer(s): A
