Difficulty: MediumShared Responsibility Model

A healthcare provider plans to migrate its electronic health record (EHR) database and patient portal from Azure Virtual Machines (IaaS) to Azure SQL Database and Azure App Service (PaaS) to streamline operations.

Which of the following responsibilities will shift from the healthcare provider to Microsoft as a result of this migration? Select two.

  1. Maintaining and patching the operating system hosting the database and portalAnswer
  2. Managing the database engine software and runtime environmentAnswer
  3. C
    Configuring database firewalls and network access rules
  4. D
    Classifying and securing the patient records and data files

Answer

Maintaining and patching the operating system hosting the database and portal, and managing the database engine software and runtime environment
When migrating from IaaS to PaaS, the responsibility for managing, patching, and maintaining the guest operating system and the database engine software/runtime environment shifts from the customer (who managed these on Azure Virtual Machines) to Microsoft (who manages them in Azure SQL Database and App Service).

Step-by-Step Solution

1
Identify the service models involved in the migration
The migration shifts resources from Infrastructure as a Service (IaaS) using Virtual Machines to Platform as a Service (PaaS) using Azure SQL Database and App Service.
Understanding the starting and target service models is essential to identify the shift in responsibilities.
2
Analyze which responsibilities belong to the customer in IaaS but are managed by Microsoft in PaaS
Operating system maintenance and database engine/runtime management are customer responsibilities in IaaS, but become Microsoft's responsibilities in PaaS.
This identifies the correct responsibilities that shift due to the migration.
3
Evaluate the remaining options against the shared responsibility model for PaaS
Data classification/security and database firewall configurations remain the customer's responsibility in PaaS.
This confirms the distractors are incorrect as they do not shift to Microsoft.
