CompTIA Cloud+ (CV0-004) — Question 63

An on-premises data center is located in an earthquake-prone location. The workload consists of real-time, online transaction processing. Which of the following data protection strategies should be used to back up on-premises data to the cloud while also being cost-effective?

Answer options

• A. Remote replication for failover
• B. A copy that is RAID 1 protected on spinning drives in an on-premises private cloud
• C. A full backup to on-site tape libraries in a private cloud
• D. Air-gapped protection to provide cyber resiliency

Correct answer: A

Explanation

The correct answer is A, as remote replication allows for continuous data backup to the cloud, ensuring data availability during disasters while being cost-efficient. Options B and C involve local storage methods that do not safeguard against site-wide disasters like earthquakes. Option D focuses on cyber resiliency rather than effective data backup in a disaster scenario.
