The development team needs to plan their operational and maintenance tasks under the Azure shared responsibility model. Which of the following tasks is the responsibility of the ticketing platform?

  1. A
    Installing security updates and operating system patches on the underlying virtual machines
  2. Deploying the custom booking API code and configuring application-level access permissionsCevap
  3. C
    Configuring virtual machine scale sets, middleware runtime, and web server installation
  4. D
    Managing user licenses and configuring mailboxes for a cloud-based productivity suite

Cevap

Deploying the custom booking API code and configuring application-level access permissions
In a Platform as a Service (PaaS) model such as Azure App Service, the cloud provider manages the physical infrastructure, virtualization layer, operating system, and runtime middleware. The customer is responsible for deploying their custom application code and configuring access permissions to that application.

Adım Adım Çözüm

1
Identify the service model used.
The scenario specifies Azure App Service, which is a Platform as a Service (PaaS) model.
Understanding the specific cloud service model is necessary to apply the correct shared responsibility division.
2
Analyze the customer's boundary of control in a PaaS model.
In PaaS, the cloud provider manages the physical infrastructure, operating systems, and middleware. The customer remains responsible for application code and data/access configurations.
This helps filter out responsibilities managed by the cloud provider (like OS patching or hardware).
3
Match the tasks to their respective responsibility owners.
Deploying the booking API code and configuring permissions is the customer's responsibility. OS patching, web server middleware configuration, and SaaS configuration are not.
Identifying the task belonging solely to the customer yields the correct answer.
