Google Cloud Associate Data Practitioner — Question 79

Your company has an on-premises file server with 5 TB of data that needs to be migrated to Google Cloud. The network operations team has mandated that you can only use up to 250 Mbps of the total available bandwidth for the migration. You need to perform an online migration to Cloud Storage. What should you do?

Answer options

• A. Use the gcloud storage cp command to copy all files from on-premises to Cloud Storage using the --daisy-chain option.
• B. Use Storage Transfer Service to configure an agent-based transfer. Set the appropriate bandwidth limit for the agent pool.
• C. Request a Transfer Appliance, copy the data to the appliance, and ship it back to Google Cloud.
• D. Use the gcloud storage cp command to copy all files from on-premises to Cloud Storage using the --no-clobber option.

Correct answer: B

Explanation

The correct answer is B because the Storage Transfer Service allows you to set specific bandwidth limits for the transfer process, which aligns with the network operations team's requirements. Option A does not provide a way to manage bandwidth, option C involves shipping physical hardware which is not an online migration, and option D also lacks the capability to control bandwidth usage.
