SY0-501 Question #432: Real Exam Question with Answer & Explanation

Question

When it comes to cloud computing, if one of the requirements for a project is to have the most control over the systems in the cloud, which of the following is a service model that would be BEST suited for this goal?

Options

• AInfrastructure
• BPlatform
• CSoftware
• DVirtualization

Explanation

To achieve the highest level of control over systems in the cloud, Infrastructure as a Service (IaaS) is the most suitable service model. IaaS allows users to manage the operating systems, applications, and data directly.

Common mistakes.

• B. Platform as a Service (PaaS) provides less control than IaaS, as the cloud provider manages the operating system, runtime, and underlying infrastructure.
• C. Software as a Service (SaaS) offers the least control, as the cloud provider manages the entire application stack and infrastructure, leaving users only with application interaction.
• D. Virtualization is a foundational technology for cloud computing, not one of the primary cloud service models (IaaS, PaaS, SaaS).
