CompTIA Cloud+ (CV0-003) — Question 362

To save on licensing costs, the on-premises, IaaS-hosted databases need to be migrated to a public DBaaS solution. Which of the following would be the BEST technique?

Answer options

• A. Live migration
• B. Physical-to-virtual
• C. Storage-level mirroring
• D. Database replication

Correct answer: D

Explanation

Database replication is the most suitable method for this scenario because it allows for the continuous copying of data in real-time to the DBaaS environment, ensuring minimal downtime. Live migration typically involves moving virtual machines, which may not be applicable here, while physical-to-virtual focuses on converting physical servers to virtual ones. Storage-level mirroring deals with data redundancy rather than migration.
