Question

Hotspot Question You have two Azure subscriptions named Prod and Dev. Prod contains resources for a production environment. Dev contains resources for a development environment. You plan to deploy a Volume Shadow Copy Service (VSS)-aware app named App1. App1 will be hosted on virtual machines that run Windows Server 2022. The deployment of App1 to Dev will use multiple disks on each virtual machine. The deployment of App1 to Prod will use shared disks on the virtual machines. You need to recommend a backup solution for App1. The solution must meet the following requirements: - Ensure that the virtual machines in Dev support up to three on-demand backups per hour. - Ensure that the virtual machines in Prod are backed up every four hours. - Provide application-consistent backups. - Minimize administrative effort. What should you include in the recommendation for each environment? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. Answer:

Explanation

This question tests knowledge of Azure Backup solutions for Windows Server VMs with VSS-aware applications, specifically the differences between Enhanced backup policy and Azure Backup with shared disks support across Dev and Prod environments.

Approach. For Dev (multiple disks, up to 3 on-demand backups per hour): Use Azure Backup with Enhanced policy. The Enhanced backup policy supports multiple backups per day (up to every 4 hours scheduled, and multiple on-demand), supports multiple disks, and provides application-consistent backups via VSS integration - meeting the requirement of up to 3 on-demand backups per hour. For Prod (shared disks, every 4 hours): Use Azure Backup with Enhanced policy as well, because only the Enhanced policy supports shared disks (Azure shared disks are not supported by the Standard backup policy) and can be configured for a 4-hour backup frequency. Application consistency is achieved via VSS integration built into the Azure VM Backup agent on Windows Server 2022. Both environments benefit from the Enhanced policy minimizing administrative effort through a single unified Azure Backup vault approach.

Concept tested. Azure Backup Enhanced policy vs Standard policy: The Enhanced policy supports hourly backups (every 1-24 hours), shared disk backups, multiple disks, and application-consistent VSS-based backups for Windows VMs. The Standard policy does NOT support shared disks and only supports one scheduled backup per day, making it unsuitable for both the Dev (multiple on-demand) and Prod (shared disks + 4-hour frequency) requirements.
