Microsoft 365 Fundamentals MS-900 Practice Question

Infrastructure as a Service (IaaS) is the correct choice because it provides virtualized computing resources over the internet. With IaaS, the cloud provider manages the physical hardware, while the company retains control over the operating systems and applications. This allows the company to customize and manage their software environment without worrying about hardware maintenance. Platform as a Service (PaaS) does not offer control over the operating system, and Software as a Service (SaaS) provides ready-to-use applications without the ability to install custom applications.
