ACE General MCQ

You are developing a new web application that will be deployed on Google Cloud Platform. As part of your release cycle, you want to test updates to your application on a small portion of real user traffic. The majority of the users should still be directed towards a stable version of your application. What should you do?

• Deploy the application on App Engine. For each update, create a new version of the same service. Configure traffic splitting to send a small percentage of traffic to the new version.

• Deploy the application on App Engine. For each update, create a new service. Configure traffic splitting to send a small percentage of traffic to the new service.

• Deploy the application on Kubernetes Engine. For a new release, update the deployment to use the new version.

• Deploy the application on Kubernetes Engine. For a new release, create a new deployment for the new version. Update the service to use the new deployment.

You need to add a group of new users to Cloud Identity. Some of the users already have existing Google accounts. You want to follow one of Google's recommended practices and avoid conflicting accounts. What should you do?

• Invite the user to transfer their existing account.

• Invite the user to use an email alias to resolve the conflict.

• Tell the user that they must delete their existing account.

• Tell the user to remove all personal email from the existing account.

You need to manage a Cloud Spanner instance for best query performance. Your instance in production runs in a single Google Cloud region. You need to improve performance in the shortest amount of time. You want to follow Google best practices for service configuration. What should you do?

• Create an alert in Cloud Monitoring to alert when the percentage of high priority CPU utilization reaches 45%. If you exceed this threshold, add nodes to your instance.

• Create an alert in Cloud Monitoring to alert when the percentage of high priority CPU utilization reaches 45%. Use database query statistics to identify queries that result in high CPU usage, and then rewrite those queries to optimize their resource usage.

• Create an alert in Cloud Monitoring to alert when the percentage of high priority CPU utilization reaches 65%. If you exceed this threshold, add nodes to your instance.

• Create an alert in Cloud Monitoring to alert when the percentage of high priority CPU utilization reaches 65%. Use database query statistics to identify queries that result in high CPU usage, and then rewrite those queries to optimize their resource usage.

Your company has an internal application for managing transactional orders. The application is used exclusively by employees in a single physical location. The application requires strong consistency, fast queries, and ACID guarantees for multi-table transactional updates. The first version of the application is implemented in PostgreSQL, and you want to deploy it to the cloud with minimal code changes. Which database is most appropriate for this application?

• BigQuery

• Cloud SQL

• Cloud Spanner

• Cloud Datastore

You are assigned to maintain a Google Kubernetes Engine (GKE) cluster named 'dev' that was deployed on Google Cloud. You want to manage the GKE configuration using the command line interface (CLI). You have just downloaded and installed the Cloud SDK. You want to ensure that future CLI commands by default address this specific cluster What should you do?

• Use the command gcloud config set container/cluster dev.

• Use the command gcloud container clusters update dev.

• Create a file called gke.default in the ~/.gcloud folder that contains the cluster name.

• Create a file called defaults.json in the ~/.gcloud folder that contains the cluster name.

The sales team has a project named Sales Data Digest that has the ID acme-data-digest. You need to set up similar Google Cloud resources for the marketing team but their resources must be organized independently of the sales team. What should you do?

• Grant the Project Editor role to the Marketing team for acme-data-digest.

• Create a Project Lien on acme-data-digest and then grant the Project Editor role to the Marketing team.

• Create another project with the ID acme-marketing-data-digest for the Marketing team and deploy the resources there.

• Create a new project named Marketing Data Digest and use the ID acme-data-digest. Grant the Project Editor role to the Marketing team.

You have deployed multiple Linux instances on Compute Engine. You plan on adding more instances in the coming weeks. You want to be able to access all of these instances through your SSH client over the internet without having to configure specific access on the existing and new instances. You do not want theCompute Engine instances to have a public IP. What should you do?

• Configure Cloud Identity-Aware Proxy for HTTPS resources.

• Configure Cloud Identity-Aware Proxy for SSH and TCP resources

• Create an SSH keypair and store the public key as a project-wide SSH Key.

• Create an SSH keypair and store the private key as a project-wide SSH Key.

You have created an application that is packaged into a Docker image. You want to deploy the Docker image as a workload on Google Kubernetes Engine. What should you do?

• Upload the image to Cloud Storage and create a Kubernetes Service referencing the image.

• Upload the image to Cloud Storage and create a Kubernetes Deployment referencing the image.

• Upload the image to Container Registry and create a Kubernetes Service referencing the image.

• Upload the image to Container Registry and create a Kubernetes Deployment referencing the image.

You are using Data Studio to visualize a table from your data warehouse that is built on top of BigQuery. Data is appended to the data warehouse during the day.At night, the daily summary is recalculated by overwriting the table. You just noticed that the charts in Data Studio are broken, and you want to analyze the problem. What should you do?

• Review the Error Reporting page in the Cloud Console to find any errors.

• Use the BigQuery interface to review the nightly job and look for any errors.

• Use Cloud Debugger to find out why the data was not refreshed correctly.

• In Cloud Logging, create a filter for your Data Studio report.

You need to manage a third-party application that will run on a Compute Engine instance. Other Compute Engine instances are already running with default configuration. Application installation files are hosted on Cloud Storage. You need to access these files from the new instance without allowing other virtual machines (VMs) to access these files. What should you do?

• Create the instance with the default Compute Engine service account. Grant the service account permissions on Cloud Storage.

• Create the instance with the default Compute Engine service account. Add metadata to the objects on Cloud Storage that matches the metadata on the new instance.

• Create a new service account and assign this service account to the new instance. Grant the service account permissions on Cloud Storage.

• Create a new service account and assign this service account to the new instance. Add metadata to the objects on Cloud Storage that matches the metadata on the new instance.
