Google Cloud Associate Cloud Engineer — Question 312

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?

Answer options

• A. Use Storage Transfer Service to move the data from the selected on-premises file storage systems to a Cloud Storage bucket.
• 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. 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.
• 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.

Correct answer: A

Explanation

The correct answer is A because using Storage Transfer Service is specifically designed for moving large amounts of data to Cloud Storage efficiently, making it ideal for this scenario. Option B involves physical shipping, which is slower and may not be necessary for infrequently accessed files. Option C requires a more complex setup with Cloud Interconnect and may not directly achieve the goal of minimizing costs. Option D, while viable, does not optimize for the bulk transfer of large data sets in a cost-effective manner.
