Question 1

What is a pod in a Kubernetes cluster?

Options :

A : Compute instances managed by Kubernetes

B : A set of containers with shared storage and network resources

C : Units within a node that can contain one or more containers with shared storage and network resources

D : A YAML file with deployment information

Answer: C

Question 2

Your application is deployed across several Google Kubernetes Engine clusters, with each cluster managed by a Deployment. The Deployment has generated several replicas of your Pod in every cluster. You intend to access the logs sent to stdout for all the replicas in your Deployment across all clusters.

What is the appropriate command to use?

Options :

A : kubectl logs [PARAM]

B : gcloud logging read [PARAM]

C : kubectl exec ""it [PARAM] journalctl

D : gcloud compute ssh [PARAM] ""-command= 'sudo journalctl'

Answer: B

Question 3

The new version of your containerized application has been tested and is ready to deploy to production on Google Kubemetes Engine. You were not able to fully load-test the new version in pre-production environments. and you need to make sure that it does not have performance problems once deployed Your deployment must be automated. What should you do?

Options :

A : Use Cloud Load Balancing to slowly ramp up traffic between versions. Use Cloud Monitoring to look for performance issues.

B : Deploy the application via a continuous delivery pipeline using canary deployments. Use Cloud Monitoring to look for performance issues. and ramp up traffic as the metrics support it.

C : Deploy the application via a continuous delivery pipeline using blue/green deployments. Use Cloud Monitoring to look for performance issues, and launch fully when the metrics support it.

D : Deploy the application using kubectl and set the spec. updateStrategv. type to RollingUpdate. Use Cloud Monitoring to look for performance issues, and run the kubectl rollback command if there are any issues.

Answer: A

Question 4

Your application will be deployed on a Compute Engine instance that will communicate with Cloud SQL. In order to allow communication between the application and the database using the service account associated with the instance, you will use Cloud SQL Proxy. It is recommended by Google to provide minimum access for the role assigned to the service account, which you intend to follow as a best practice.

Question 5

A stateless web application for a marquee is being developed for Google Cloud. It is expected that the incoming user traffic will be unpredictable, with some days having no traffic while other days will have large spikes. The application should be able to automatically scale up and down, while minimizing the cost associated with running the application.

What actions do you need to take?

Options :

A : Use Python and Firestore to build the application, then deploy it to a managed instance group with autoscaling on Compute Engine.

B : Create the application with C# and Firestore, and deploy it to App Engine-s flexible environment.

C : Build the application using Python and Firestore, then deploy it to Cloud Run.

D : Develop the application with Python and CloudSQL, and deploy it to App Engine-s standard environment.

Answer: C
