Difficulty: MediumPlatform as a Service (PaaS)

An online retail company is planning to migrate its product catalog API to Azure App Service, a Platform as a Service (PaaS) offering. Under the Azure shared responsibility model, which of the following tasks are the responsibility of the customer? (Select two.)

  1. Configuring application settings and managing the deployed codeAnswer
  2. B
    Applying security patches to the underlying virtual machine operating system
  3. Securing the application data and controlling user access permissionsAnswer
  4. D
    Managing software licensing and updates for SaaS productivity suites

Answer

Configuring application settings and managing the deployed code, and Securing the application data and controlling user access permissions
In a Platform as a Service (PaaS) deployment, the cloud provider manages the physical hardware, virtualization layer, and the operating system. The customer retains control over the application (including custom code and settings) and the data hosted within the application, along with identity and access management.

Step-by-Step Solution

1
Identify the cloud deployment model described in the scenario.
The scenario specifies Azure App Service, which is a Platform as a Service (PaaS) model.
Understanding the deployment model allows you to determine the split of responsibilities between the customer and Microsoft.
2
Apply the shared responsibility model rules for PaaS deployments.
Under PaaS, Microsoft manages physical infrastructure, virtualization, and the operating system. The customer is responsible for the application, data, and access management.
This isolates which tasks are handled by the customer and which are offloaded to Microsoft.
3
Evaluate the choices to match customer responsibilities.
Configuring application settings/code and securing data/user access are customer responsibilities. OS patching is a provider responsibility, and SaaS application licensing is irrelevant to PaaS custom hosting.
Ensures selection of only correct answers based on the mapped responsibilities.
