Certified Cloud Security Professional (CCSP) — Question 27

When using an IaaS solution, what is a key benefit provided to the customer?

Answer options

• A. Metered and priced on the basis of units consumed
• B. Increased energy and cooling system efficiencies
• C. Transferred cost of ownership
• D. The ability to scale up infrastructure services based on projected usage

Correct answer: D

Explanation

The ability to scale up infrastructure services based on projected usage is a key benefit of IaaS, allowing customers to adjust resources as needed. While metering and pricing based on consumption (A) and improved energy efficiencies (B) are advantages, they do not provide the same level of flexibility. Transferred cost of ownership (C) is also not as directly related to the scalability benefit of IaaS solutions.
