CompTIA A+ Core 1 (220-1001) — Question 73

An end user has signed up to use a web-based calendar application.
Which of the following solutions has the user purchased?

Answer options

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

Correct answer: B

Explanation

The user has purchased Software as a Service (SaaS) since they are utilizing a web-based application for their calendar needs. DaaS (Desktop as a Service), PaaS (Platform as a Service), and IaaS (Infrastructure as a Service) do not apply here as they refer to different service models that do not specifically provide user-facing applications.
