CompTIA Cloud+ (CV0-003) — Question 10

An IaaS application has a two-hour RTO and four-hour RPO. The application takes one hour to back up its data or restore from a local backup file. A systems administrator is tasked with configuring the backup policy. Which of the following should the administrator configure to achieve the application requirements with the LEAST cost?

Answer options

• A. Back up to long-term storage every night.
• B. Back up to object storage every three hours.
• C. Back up to long-term storage every four hours.
• D. Back up to object storage every hour.

Correct answer: B

Explanation

Option B is correct because backing up to object storage every three hours ensures that the RPO of four hours is met while minimizing costs. Options A and C do not satisfy the RPO requirement without incurring additional costs, and option D provides more frequent backups than necessary, which would increase costs without additional benefit.
