EMC Proven Professional – Technology Architect — Question 1

Which cloud service model enables an organization to deploy a proprietary operating system and applications on a cloud provider’s resources?

Answer options

• A. Infrastructure as a Service
• B. Platform as a Service
• C. Software as a Service
• D. Desktop as a Service

Correct answer: A

Explanation

Infrastructure as a Service (IaaS) provides the most fundamental cloud services, allowing organizations to manage their own operating systems and applications on the infrastructure provided by the cloud provider. In contrast, Platform as a Service (PaaS) and Software as a Service (SaaS) offer more managed environments and applications, while Desktop as a Service (DaaS) focuses on virtual desktop access rather than OS installation.
