Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

Udemy is an example of what kind of service?

1. SaaS

2. PaaS

3. IaaS

4. None of the above

The correct answer is: SaaS

Udemy is an example of Software as a Service (SaaS) because it provides users with access to an online platform where they can take courses and access educational content over the internet. In a SaaS model, users do not need to manage the underlying infrastructure or application software; they simply use the provided service through a web browser. This allows for ease of access and scale since all necessary resources are managed by Udemy, making it user-friendly and accessible from anywhere with an internet connection. The other options are relevant to different service models: Platform as a Service (PaaS) typically involves services that allow developers to create applications without worrying about the infrastructure, and Infrastructure as a Service (IaaS) refers to virtualized computing resources over the internet. However, Udemy does not fit these models as it is focused on delivering software directly to users rather than providing a platform for development or infrastructure.
