  1. Servicing physical host hardware in the data centerAnswer
  2. Applying software updates and security patches to the applicationAnswer
  3. C
    Managing individual user accounts and access permissions
  4. D
    Configuring virtual network adapters on the host virtual machines

Answer

Servicing physical host hardware and applying software updates and security patches to the application are the responsibility of the cloud service provider.
Under the Software as a Service (SaaS) cloud service model, the cloud service provider manages the complete underlying infrastructure. This includes servicing physical server hardware in data centers as well as maintaining, patching, and updating the application software itself.

Step-by-Step Solution

1
Evaluate the SaaS cloud model boundaries within the shared responsibility model.
In Software as a Service (SaaS), the service provider hosts and manages the entire application stack, including physical hardware, OS, middleware, and application software.
Understanding the management boundary helps separate vendor responsibilities from subscriber duties.
2
Identify vendor-managed tasks from the provided choices.
Maintaining physical server hardware and delivering application patches fall strictly on the cloud vendor.
SaaS subscribers consume finished software and do not perform infrastructure or application-level maintenance.
