CompTIA Security+ (SY0-601) — Question 161

Which of the following BEST describes when an organization utilizes a ready-to-use application from a cloud provider?

Answer options

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

Correct answer: B

Explanation

The correct answer is B (SaaS), which stands for Software as a Service, where users access software applications hosted in the cloud. A is incorrect as IaaS refers to Infrastructure as a Service, which provides virtualized computing resources. C (PaaS) indicates Platform as a Service, which offers a platform for developers to build applications, while D (XaaS) means Anything as a Service and is a broader term that doesn't specifically address ready-to-use applications.
