CompTIA Network+ (N10-008) — Question 62

Which of the following service models would MOST likely be used to replace on-premises servers with a cloud solution?

Answer options

• A. PaaS
• B. IaaS
• C. SaaS
• D. Disaster recovery as a Service (DRaaS)

Correct answer: B

Explanation

IaaS (Infrastructure as a Service) is the correct choice because it provides virtualized computing resources over the internet, allowing for the replacement of on-premises servers. PaaS (Platform as a Service) and SaaS (Software as a Service) serve different purposes, focusing on application development and software delivery, respectively. DRaaS, while valuable for recovery, is not designed to directly replace server infrastructure.
