CompTIA Security+ (SY0-601) — Question 114

To reduce and limit software and infrastructure costs, the Chief Information Officer has requested to move email services to the cloud. The cloud provider and the organization must have security controls to protect sensitive data. Which of the following cloud services would BEST accommodate the request?

Answer options

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

Correct answer: D

Explanation

The correct answer is D (SaaS), as Software as a Service provides complete email solutions that are managed in the cloud, including necessary security controls. IaaS (A) and PaaS (B) do not provide ready-to-use email services, and DaaS (C) is focused on desktop virtualization rather than email services.
