CompTIA Cloud Essentials+ (CLO-002) — Question 52

A company wants to deploy an application in a public cloud. Which of the following service models gives the MOST responsibility to the provider?

Answer options

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

Correct answer: A

Explanation

PaaS (Platform as a Service) provides the highest level of responsibility to the provider, as it manages the underlying infrastructure and platform for the application, allowing developers to focus on code. In contrast, IaaS (Infrastructure as a Service) provides more control to the user over the infrastructure, while SaaS (Software as a Service) delivers complete software solutions with less flexibility. BPaaS (Business Process as a Service) is more focused on business processes rather than application deployment.
