PK0-005 Question #119: Real Exam Question with Answer & Explanation

Question

A company wants to move its data from on premises to off premises. Which of the following cloud models should be pursued?

Options

• AXaaS
• BSaaS
• CPaaS
• DIaaS

Explanation

When a company wants to move its data off-premises while maintaining control over its operating systems and applications, Infrastructure as a Service (IaaS) is the most suitable cloud model. IaaS provides the fundamental compute, storage, and networking resources in a virtualized environment.

Common mistakes.

• A. XaaS (Anything as a Service) is a broad category encompassing various cloud services, not a specific model for moving existing data.
• B. SaaS (Software as a Service) delivers ready-to-use applications over the internet, with the provider managing the underlying infrastructure and software, which is not suitable if the company wants to control its own data migration and stack.
• C. PaaS (Platform as a Service) provides a platform for developing, running, and managing applications without the complexity of building and maintaining the infrastructure typically associated with IaaS. It's more about application development than raw data migration where the customer retains OS/application control.
