Your digital media company stores a large number of video files on-premises. Each video file ranges from 100 MB to 100 GB. You are currently storing 150 TB of video data in your on- premises network, with no room for expansion. You need to migrate all infrequently accessed video files older than one year to Cloud Storage to ensure that on-premises storage remains available for new files. You must also minimize costs and control bandwidth usage. What should you do?

• A. Set up a Cloud Interconnect connection between the on-premises network and Google Cloud.
  Establish a private endpoint for Filestore access. Transfer the data from the existing Network File System (NFS) to Filestore.
• B. Use Transfer Appliance to request an appliance. Load the data locally, and ship the appliance back to Google for ingestion into Cloud Storage.
• C. Use Storage Transfer Service to move the data from the selected on-premises file storage systems to a Cloud Storage bucket.
• D. Create a Cloud Storage bucket. Establish an Identity and Access Management (IAM) role with write permissions to the bucket. Use the gsutil tool to directly copy files over the network to Cloud Storage.

You are the Organization Administrator for your company's Google Cloud resources. Your company has strict compliance rules that require you to be notified about any modifications to files and documents hosted on Cloud Storage. In a recent incident, one of your team members was able to modify files and you did not receive any notifications, causing other production jobs to fail. You must ensure that you receive notifications for all changes to files and documents in Cloud Storage while minimizing management overhead. What should you do?

• A. Enable versioning on the Cloud Storage bucket. Set up a custom script that scans versions of Cloud Storage objects being modified and alert the admin by using the script.
• B. View Cloud Audit logs for all Cloud Storage files in Logs Explorer. Filter by Admin Activity logs.
• C. Configure Object change notifications on the Cloud Storage buckets. Send the events to Pub/Sub.
• D. Enable Cloud Storage object versioning on your bucket. Configure Pub/Sub notifications for your Cloud Storage buckets.

You need to estimate the annual cost of running a Bigquery query that is scheduled to run nightly.
What should you do?

• A. Use "bq query --dry_run" to determine the number of bytes read by the query. Use this number in the Pricing Calculator.
• B. Use "gcloud estimate" to determine the amount billed for a single query. Multiply this amount by
  365.
• C. Use "gcloud query --dry_run" to determine the number of bytes read by the query. Use this number in the Pricing Calculator.
• D. Use "bq estimate" to determine the amount billed for a single query. Multiply this amount by 365.

You want to configure autohealing for network load balancing for a group of Compute Engine instances that run in multiple zones, using the fewest possible steps. You need to configure re- creation of VMs if they are unresponsive after 3 attempts of 10 seconds each. What should you do?

• A. Create an HTTP load balancer with a backend configuration that references an existing instance group.
  Define a balancing mode and set the maximum RPS to 10.
• B. Create a managed instance group. Verify that the autoscaling setting is on.
• C. Create an HTTP load balancer with a backend configuration that references an existing instance group.
  Set the health check to healthy (HTTP)
• D. Create a managed instance group. Set the Autohealing health check to healthy (HTTP)
