Your company has an application that is running on multiple instances of Compute Engine. It generates 1 TB per day of logs. For compliance reasons, the logs need to be kept for at least two years. The logs need to be available for active query for 30 days. After that, they just need to be retained for audit purposes. You want to implement a storage solution that is compliant, minimizes costs, and follows Google-recommended practices. What should you do?

A. 1. Install the Cloud Ops agent on all instances.

2.

Create a sink to export logs into a partitioned BigQuery table.

3.

Set a time_partitioning_expiration of 30 days.

B. 1. Install the Cloud Ops agent on all instances.

2.

Create a sink to export logs into a regional Cloud Storage bucket.

3.

Create an Object Lifecycle rule to move files into a Coldline Cloud Storage bucket after one month.

4.

Configure a retention policy at the bucket level to create a lock.

C. 1. Create a daily cron job, running on all instances, that uploads logs into a partitioned BigQuery table.

2. Set a time_partitioning_expiration of 30 days.

D. 1. Write a daily cron job, running on all instances, that uploads logs into a Cloud Storage bucket.

2.

Create a sink to export logs into a regional Cloud Storage bucket.

3.

Create an Object Lifecycle rule to move files into a Coldline Cloud Storage bucket after one month.

You are designing an application for use only during business hours. For the minimum viable product release, you'd like to use a managed product that automatically "scales to zero" so you don't incur costs when there is no activity.

Which primary compute resource should you choose?

A. Cloud Functions

B. Compute Engine

C. Kubernetes Engine

D. AppEngine flexible environment

You have an application that will run on Compute Engine. You need to design an architecture that takes into account a disaster recovery plan that requires your application to fail over to another region in case of a regional outage. What should you do?

A. Deploy the application on two Compute Engine instances in the same project but in a different region. Use the first instance to serve traffic, and use the HTTP load balancing service to fail over to the standby instance in case of a disaster.

B. Deploy the application on a Compute Engine instance. Use the instance to serve traffic, and use the HTTP load balancing service to fail over to an instance on your premises in case of a disaster.

C. Deploy the application on two Compute Engine instance groups, each in the same project but in a different region. Use the first instance group to serve traffic, and use the HTTP load balancing service to fail over to the standby instance group in case of a disaster.

D. Deploy the application on two Compute Engine instance groups, each in separate project and a different region. Use the first instance group to server traffic, and use the HTTP load balancing service to fail over to the standby instance in case of a disaster.

You want to enable your running Google Kubernetes Engine cluster to scale as demand for your application changes.

What should you do?

A. Add additional nodes to your Kubernetes Engine cluster using the following command:gcloud container clusters resizeCLUSTER_Name ?-size 10

B. Add a tag to the instances in the cluster with the following command:gcloud compute instances add-tagsINSTANCE--tags enable-autoscaling max-nodes-10

C. Update the existing Kubernetes Engine cluster with the following command:gcloud alpha container clustersupdate mycluster--enable-autoscaling--min-nodes=1--max-nodes=10

D. Create a new Kubernetes Engine cluster with the following command:gcloud alpha container clusterscreate mycluster--enable-autoscaling--min-nodes=1--max-nodes=10and redeploy your application

You are designing a large distributed application with 30 microservices. Each of your distributed microservices needs to connect to a database back-end. You want to store the credentials securely. Where should you store the credentials?

A. In the source code

B. In an environment variable

C. In a secret management system

D. In a config file that has restricted access through ACLs
