CompTIA A+ Core 1 (220-1101) — Question 547

In which of the following cloud models is the customer not responsible for hardware and OS layers but is responsible for the data and the application?

Answer options

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

Correct answer: A

Explanation

The correct answer is A, PaaS, as it provides a platform that abstracts the underlying hardware and operating system, allowing customers to focus on developing and managing their applications and data. In contrast, SaaS (B) delivers software solutions over the internet, IaaS (C) requires customers to manage OS and hardware, and CaaS (D) is more focused on container management, which still involves some infrastructure responsibilities.
