CompTIA Cloud+ (CV0-004) — Question 4

A company’s engineering department is conducting a month-long test on the scalability of an in-house-developed software that requires a cluster of 100 or more servers. Which of the following models is the best to use?

Answer options

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

Correct answer: D

Explanation

The correct answer is D, IaaS, because it provides the necessary infrastructure resources, such as virtual machines and storage, to support a large cluster of servers. PaaS and SaaS do not offer the level of infrastructure control needed for extensive server clusters, while DBaaS specifically focuses on database management rather than general infrastructure provisioning.
