Which statement about cloud service users is most accurate?

• A. Customers must manage the underlying hardware themselves
• B. Customers must configure virtualization layers
• C. Customers are required to own data centers
• D. The customer does not need to know about or have expertise in the technology behind the service

Answer: (D)

Cloud services are designed so you rely on the provider for the underlying technology, so you don’t have to manage or know the intricate details of hardware, virtualization, or data centers. In practice, especially with Software as a Service, you simply use the application and handle your data and configuration at a high level, while the provider takes care of the rest. This makes the idea that the customer does not need to know about or have expertise in the technology behind the service the most accurate statement. The other options imply responsibilities (like managing hardware or configuring virtualization or owning data centers) that are typically handled by the provider.
