  1. Configuring the firewall rules within the guest operating system of the Azure VMAnswer
  2. Installing updates for applications hosted on the Azure VMAnswer
  3. C
    Patching the underlying physical hypervisors hosting the Azure VM
  4. D
    Maintaining the physical security of the Azure datacenter facilities

Answer

Configuring the firewall rules within the guest operating system of the Azure VM, and installing updates for applications hosted on the Azure VM
In an Infrastructure as a Service (IaaS) cloud model, the customer is responsible for everything from the operating system layer and up. This includes configuration of OS firewalls and security settings, as well as the application lifecycle management. The cloud provider retains responsibility for the physical hosts, virtualization hypervisors, physical networks, and physical security of the datacenters.

Step-by-Step Solution

1
Determine the cloud model category of the resource in the scenario.
An Azure VM represents Infrastructure as a Service (IaaS).
Identifying the model helps locate the boundary lines of the shared responsibility model.
2
Differentiate between customer and provider responsibilities in an IaaS setup.
The customer is responsible for the guest operating system, applications, middleware, and data. The cloud provider is responsible for physical hosts, physical network, physical datacenters, and hypervisors.
Applying this rule allows us to classify the responsibilities listed in the choices.
