Difficulty: MediumInfrastructure as a Service (IaaS)

A global shipping company is migrating its legacy container tracking software to Azure Virtual Machines (IaaS) to maintain a specific operating system configuration. Under the Azure shared responsibility model, which task is Microsoft responsible for performing?

  1. Maintaining the physical server hardware and the virtualization hypervisorAnswer
  2. B
    Configuring the database engine settings and middleware applications on the virtual machines
  3. C
    Applying security patches and operating system updates to the virtual machines
  4. D
    Configuring network security groups and virtual network rules to protect the application

Answer

Maintaining the physical server hardware and the virtualization hypervisor
Under the Infrastructure as a Service (IaaS) model, Microsoft's responsibility is limited to the physical infrastructure, which includes the physical servers, storage, network hardware, power systems, and the virtualization hypervisor layer that hosts the virtual machines.

Step-by-Step Solution

1
Identify the cloud service model referenced in the scenario.
The scenario specifies Azure Virtual Machines, which represents the Infrastructure as a Service (IaaS) model.
Determining the correct service model is necessary to apply the corresponding shared responsibility boundaries.
2
Determine the boundary of responsibility between the customer and Microsoft in an IaaS deployment.
In IaaS, Microsoft manages the physical infrastructure, physical networking, storage hardware, and the hypervisor layer. The customer is responsible for everything from the operating system upward.
This division determines which of the listed options is performed by Microsoft rather than the customer.
3
Evaluate the given options against the identified responsibility boundary.
Maintaining physical servers and the hypervisor is a Microsoft responsibility. Guest OS patching, middleware/database configuration, and network security group settings are customer responsibilities.
To select the correct option representing Microsoft's responsibility.
