In which of the following situations does the data owner have to administer the OS? Response:

With Infrastructure as a Service (IaaS), the cloud provider manages the underlying hardware, virtualization, servers, storage, and networking, but the customer is responsible for managing the operating systems, middleware, runtime environments, and applications. This includes tasks like patching and configuring the OS.

In Platform as a Service (PaaS), the cloud provider manages the operating system, middleware, and runtime environment, allowing the customer to focus solely on their applications and data.

An offsite archive is a data storage solution where the customer typically manages the data itself, but the service provider manages the underlying infrastructure, including any operating systems of the storage servers.

With Software as a Service (SaaS), the cloud provider manages all aspects of the application, including the operating system, middleware, and data, with the customer only interacting with the application itself.
