CompTIA Security+ (SY0-601) — Question 561

Which of the following best describes an environment where a business owns the application and operating system but requires the resources to host them in the cloud?

Answer options

• A. IaaS
• B. XaaS
• C. PaaS
• D. SaaS

Correct answer: A

Explanation

The correct answer is A (IaaS), as it refers to Infrastructure as a Service, where the customer owns the applications and operating system but utilizes cloud resources for hosting. Options B (XaaS) is too broad, encompassing various services, while C (PaaS) implies that the platform is provided, and D (SaaS) suggests that the software is managed by the vendor, not the customer.
