CompTIA Cloud+ (CV0-003) — Question 265

A cloud engineer needs to perform a database migration. The database has a restricted SLA and cannot be offline for more than ten minutes per month. The database stores 800GB of data, and the network bandwidth to the CSP is 100MBps. Which of the following is the best option to perform the migration?

Answer options

• A. Copy the database to an external device and ship the device to the CSP
• B. Create a replica database synchronize the data, and switch to the new instance.
• C. Utilize a third-party tool to back up and restore the data to the new database
• D. Use the database import/export method and copy the exported file.

Correct answer: B

Explanation

The best option is B because creating a replica database allows for continuous synchronization of data with minimal downtime, which meets the SLA requirements. Option A involves shipping physical media, which is impractical given the downtime limit. Option C, while feasible, may not ensure the needed uptime, and option D could take longer than the allowable downtime due to the size of the database.
