Question

Hotspot Question You have an Azure subscription named Subscription1. You have a virtualization environment that contains the virtualization servers in the following table. The virtual machines are configured as shown in the following table. All the virtual machines use basic disks. VM1 is protected by using BitLocker Drive Encryption (BitLocker). You plan to use Azure Site Recovery to migrate the virtual machines to Azure. Which virtual machines can you migrate? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. Answer:

Answer Area

  • VM1No
  • VM2Yes
  • VM3Yes
  • VMAYes
  • VMBYes
  • VMCYes

Explanation

Azure Site Recovery migration requires OS disks to be 2048 GB or less, data disks to be 4095 GB or less, and BitLocker to be disabled.

Approach. For Server1, select 'VM3'. VM1 is excluded because Azure Site Recovery (ASR) does not support replicating VMs with BitLocker enabled; it must be disabled first. VM2 is excluded because its 3 TB OS disk exceeds the 2048 GB (2 TB) maximum limit for OS disks in Azure. For Server2, select 'VMA and VMB only'. VMC is excluded because its 6 TB data disk exceeds the traditional ASR maximum data disk size limit of 4095 GB (4 TB) for replication.

Common mistakes.

  • common_mistake. A common mistake is selecting VM1, unaware that BitLocker prevents ASR replication, or selecting VM2/VMC by failing to account for the strict 2 TB OS disk and 4 TB data disk size limitations enforced by ASR prerequisites.

Concept tested. Azure Site Recovery (ASR) prerequisites, VM compatibility, and Azure virtual machine disk size limits.
