CompTIA A+ Core 1 (220-1201) — Question 43

A company needs to develop a disaster recovery solution based on virtual machines. Which of the following service models is the most suitable?

Answer options

• A. Infrastructure as a service
• B. Security as a service
• C. Platform as a service
• D. Software as a service

Correct answer: A

Explanation

Infrastructure as a service (IaaS) is the most suitable model for disaster recovery with virtual machines because it provides the necessary infrastructure resources such as storage, networking, and virtualization. The other options—Security as a service, Platform as a service, and Software as a service—do not focus on providing the underlying infrastructure needed for effective disaster recovery.
