Question 10 (Topic 1)

Your company follows Site Reliability Engineering principles. You are writing a postmortem for an incident, triggered by a software change that severely affected users. You want to prevent severe incident from happening in the future. What should you do?

Select an option, then click Submit answer.

○ Identify engineers responsible for the incident and escalate to the senior management.
○ Ensure that test cases that catch errors of this type are run successfully before new software releases.
○ Follow up with the employees who reviewed the changes and prescribe practices they should follow in the future.
○ Design a policy that will require on-call teams to immediately call engineers and management to discuss a plan of action if an incident occurs.

Question 11 (Topic 1)

You are creating Cloud Logging sinks to export log entries from Cloud Logging to BigQuery for future analysis. Your organization has a Google Cloud folder named Dev that contains development projects and a folder named Prod that contains production projects. Log entries for development projects must be exported to dev_dataset, and log entries for production projects must be exported to prod_dataset. You need to minimize the number of log sinks created, and you want to ensure that the log sinks apply to future projects. What should you do?

Select an option, then click Submit answer.

○ Create a single aggregated log sink at the organization level.
○ Create a log sink in each project.
○ Create two aggregated log sinks at the organization level, and filter by project ID.
○ Create an aggregated log sink in the Dev and Prod folders.

Reference / correct answer:

Create an aggregated log sink in the Dev and Prod folders.

Most accepted answer: D. Create an aggregated log sink in the Dev and Prod folders.

Community votes: D=2

I vote for D upvoted 6 times

Selected Answer: D To minimize the number of log sinks and ensure that the log sink configurations are applied to future projects, the optimal choice is Option D. By creating an aggregated log sink at the folder level for both the Dev and Prod folders, you can enforce consistent export configurations for all existing and forthcoming projects within each folder. This approach facilitates centralized management, eliminating the need for creating individual sinks for each project. It reduces complexity and ensures that any new projects added to the Dev or Prod folders will automatically adopt the log sink configuration, streamlining the process and fostering uniformity throughout the organization. upvoted 2 times

Selected Answer: D need to create two sinks at folder level. if there is new projects inside each folder, the rule will be applied to them too upvoted 1 times

D for sure. upvoted 3 times

C. Create two aggregated log sinks at the organization level, and filter by project ID. By creating two aggregated log sinks at the organization level and applying filters based on project ID, you can achieve the desired log entry routing for both development and production projects. This approach allows for scalability and ensures that future projects in the respective folders will inherit the log sink configurations. upvoted 2 times elskander 1 year, 8 months ago but doesn't apply for future projects hence D is a better option upvoted 3 times ... syslog 1 year, 10 months ago I vote for D. If you use project ID, you can't scale. Your explanation also suggests D, because if you configure the sink at folder level, all projects into folder (present and future) inherit the sink. upvoted 2 times ...

Question 12 (Topic 1)

You are building the CI/CD pipeline for an application deployed to Google Kubernetes Engine (GKE). The application is deployed by using a Kubernetes Deployment, Service, and Ingress. The application team asked you to deploy the application by using the blue/green deployment methodology. You need to implement the rollback actions. What should you do?

Select an option, then click Submit answer.

○ Run the kubectl rollout undo command.
○ Delete the new container image, and delete the running Pods.
○ Update the Kubernetes Service to point to the previous Kubernetes Deployment.
○ Scale the new Kubernetes Deployment to zero.

Reference / correct answer:

Update the Kubernetes Service to point to the previous Kubernetes Deployment.

Most accepted answer: C. Update the Kubernetes Service to point to the previous Kubernetes Deployment.

Community votes: C=3

Selected Answer: C The point of using blue/green deployment is to have both blue & green versions deployed, and we chose the active one at service level, so rollback should only consist of updating the service to serve the other version. upvoted 11 times

Selected Answer: C As seen in question 112, we can have blue & green deployments and just need to point the service to the correct deployment for rollback upvoted 1 times

Selected Answer: C To implement rollback actions in a blue/green deployment methodology for an application deployed on Google Kubernetes Engine (GKE), the recommended approach is (Option C). Updating the Kubernetes Service to point to the previous Kubernetes Deployment effectively rolls back the service to the previous version. This action ensures that traffic is directed to the previous deployment, mitigating any issues introduced by the new version. It is a controlled and Kubernetes-native way to perform rollbacks, allowing for seamless transitions between different versions of the application without downtime. Using the kubectl rollout undo command (option A) is another rollback method, but updating the Service provides a cleaner and more declarative approach within the Kubernetes environment. upvoted 2 times

A appears correct answer upvoted 1 times PrayasMohanty 2 years, 3 months ago C appears more correct as it is a blue/green deployment. upvoted 2 times ...

C appears more correct as it is a blue/green deployment. upvoted 2 times
