Your company’s product team has a new requirement based on customer demand to autoscale your stateless and distributed service running in a Google Kubernetes Engine (GKE) duster. You want to find a solution that minimizes changes because this feature will go live in two weeks. What should you do?

1. A. Deploy a Vertical Pod Autoscaler, and scale based on the CPU load.
2. B. Deploy a Vertical Pod Autoscaler, and scale based on a custom metric.
3. C. Deploy a Horizontal Pod Autoscaler, and scale based on the CPU toad.
4. D. Deploy a Horizontal Pod Autoscaler, and scale based on a custom metric.

Correct Answer: C
https://cloud.google.com/kubernetes-engine/docs/concepts/horizontalpodautoscaler
The Horizontal Pod Autoscaler changes the shape of your Kubernetes workload by automatically increasing or decreasing the number of Pods in response to the workload's CPU or memory consumption, or in response to custom metrics reported from within Kubernetes or external metrics from sources outside of your cluster.

You are planning to migrate a MySQL database to the managed Cloud SQL database for Google Cloud. You have Compute Engine virtual machine instances that will connect with this Cloud SQL instance. You do not want to whitelist IPs for the Compute Engine instances to be able to access Cloud SQL.
What should you do?

1. A. Enable private IP for the Cloud SQL instance.
2. B. Whitelist a project to access Cloud SQL, and add Compute Engine instances in the whitelisted project.
3. C. Create a role in Cloud SQL that allows access to the database from external instances, and assign the Compute Engine instances to that role.
4. D. Create a CloudSQL instance on one projec
5. E. Create Compute engine instances in a different project.Create a VPN between these two projects to allow internal access to CloudSQL.

Correct Answer: C

You are using Cloud Build to build a Docker image. You need to modify the build to execute unit and run integration tests. When there is a failure, you want the build history to clearly display the stage at which the build failed.
What should you do?

1. A. Add RUN commands in the Dockerfile to execute unit and integration tests.
2. B. Create a Cloud Build build config file with a single build step to compile unit and integration tests.
3. C. Create a Cloud Build build config file that will spawn a separate cloud build pipeline for unit and integration tests.
4. D. Create a Cloud Build build config file with separate cloud builder steps to compile and execute unit and integration tests.

Correct Answer: D
