CompTIA Cloud+ (CV0-003) — Question 358

An organization suffered a critical failure of its primary datacenter and made the decision to switch to the DR site. After one week of using the DR site, the primary datacenter is now ready to resume operations.
Which of the following is the MOST efficient way to bring the block storage in the primary datacenter up to date with the DR site?

Answer options

• A. Set up replication.
• B. Copy the data across both sites.
• C. Restore incremental backups.
• D. Restore full backups.

Correct answer: A

Explanation

Establishing replication is the most efficient way to keep the block storage in sync, as it allows for continuous updates without the need to transfer large amounts of data manually. Copying data across both sites or restoring backups may take longer and cause downtime, making them less efficient options for this scenario.
