  1. Configuring the guest operating system settings and applying security patchesCevap
  2. Installing and maintaining the runtime environment and middleware for the dispatch systemCevap
  3. C
    Maintaining the physical servers and host virtualization software
  4. D
    Securing the physical data center facility hosting the virtual machines

Cevap

Configuring the guest operating system settings and applying security patches, and installing and maintaining the runtime environment and middleware for the dispatch system are correct.
In Infrastructure as a Service (IaaS), the cloud provider is responsible for the physical host infrastructure, storage, network, and virtualization layer. The customer is responsible for managing the guest operating system, middleware, and applications. Therefore, configuring the guest operating system settings and applying patches, as well as installing and maintaining middleware/runtimes, are customer responsibilities.

Adım Adım Çözüm

1
Analyze the service model context.
The scenario describes deploying Azure Virtual Machines, which represents Infrastructure as a Service (IaaS).
Identifying the cloud model (IaaS) determines the boundaries of the shared responsibility model.
2
Evaluate the division of responsibility in IaaS.
Under IaaS, the cloud provider manages the physical hosts, physical network, and virtualization layer. The customer manages the guest operating systems, middleware, databases, applications, network controls, and data/access.
Applying this division allows us to classify each option as a customer or provider responsibility.
3
Verify which options map to customer responsibilities.
Configuring the guest operating system and installing/maintaining middleware are customer duties, whereas physical server maintenance and physical datacenter security are managed by Microsoft.
This confirms the two correct selections.
