Be careful! it's not the same as question 23. In the previous ones, server 1 is vm-ware and server 2 is hyper-V. In this case is the opposite. vm-ware support up to 32 TB for data disks: https://docs.microsoft.com/en-us/azure/migrate/migrate-support-matrix-hyper-v-migration So correct answer is VM-A,VM-B,VM-C

Azure Migrate and Azure Site Recovery are two different migration options: https://docs.microsoft.com/en-us/azure/site-recovery/migrate-overview. For example, for Hyper-V: https://docs.microsoft.com/en-us/azure/migrate/migrate-support-matrix-hyper-v-migration vs https://docs.microsoft.com/en-us/azure/site-recovery/hyper-v-azure-support-matrix#azure-vm-requirements. The migration option doesn't have a difference between 1st and 2nd generation 300GB vs 2TB for Azure system disk and there is the 8Tb limit for the Hyper-V VM data disk The VMWare data disk limitation is relevant to the migration scenario while the exam question is about using Azure Site Recovery (disaster recovery). There is an article regarding the VMWare migration using the ASR, but it doesn't mention the disk limits: https://docs.microsoft.com/en-us/azure/site-recovery/vmware-azure-about-disaster-recovery

actually, i did find the option for VMWare DR scenario: https://docs.microsoft.com/en-us/azure/site-recovery/vmware-physical-azure-support-matrix. 2TB for Gen1, 2TB for Gen 2. Regarding the data disks: "Up to 32,767 GB when replicating to managed disk (9.41 version onwards) Up to 4,095 GB when replicating to storage account Minimum disk size requirement - at least 1024 MB"

Actually the documentation is ambigous. https://docs.microsoft.com/en-us/azure/migrate/migrate-support-matrix-hyper-v-migration For the source Hyper-V VM it says: "Disk size: up to 2 TB OS disk, 8 TB for the data disks." But for the destination Azure VM it says: "Data disk size: Up to 4,095 GB" So ... you can migrate VMs with 8 TB disk as long as the disk is not larger than 4 TB ... huh?

Maybe this has been updated since you posted. but that page for Hyper-v now says up to 4, not 8, for data disk. "Disk size: up to 2 TB OS disk, 4 TB for the data disks." https://docs.microsoft.com/en-us/azure/migrate/migrate-support-matrix-hyper-v-migration

What about VM3. In my opinion it meets requirements for HyperV migration as well

Yes, it does. Not encrypted, OS disk < 300 GB, data disk < 2 TB.

You're right, acasella. Vm-ware and Hyper-V are inverted compared to question 23 and also question 52. Vmware limits: 2 TB OS and 32 TB data Hyper-V limits: 2 TB OS and 8 TB data So: VM3 VMA-VMB-VMC

The question is a bit weird as it's asking about 'using Azure Site Recovery to migrate', while you'd typically use Azure Site Recovery for DR purposes and Azure Migrate for migrating. But anyway. VM1 = No. Would meet specs but uses Bitlocker. VM2 = No. OS disk too big, max. 2 TB for Hyper-V Gen 1. VM3 = Yes. OS disk < 300 GB, data disk < 4 TB, no encryption. VMA = Yes. OS disk < 2 TB, data disk < 32 TB, no encryption. VMB = Yes. OS disk < 2 TB, data disk < 32 TB, no encryption. VMC = Yes. OS disk < 2 TB, data disk < 32 TB but > 4 TB, no encryption. Can be migrated with Managed Disks (not with disks in Storage Account).

https://docs.microsoft.com/en-us/azure/site-recovery/vmware-physical-azure-support-matrix OS disk size: Up to 2,048 GB for Generation 1 machines. (BIOS boot type) Up to 4,095 GB for Generation 2 machines. (EFI boot type) Data disk size: Up to 32,767 GB when replicating to managed disk (9.41 version onwards) Up to 4,095 GB when replicating to storage account Minimum disk size requirement - at least 1024 MB So can VM2 be migrated using Gen2 machines? How do we know the VM2 (red hat) is not EFI boot type?

VM2 is Hyper-V Generation 1, which uses BIOS boot. Generation 2 uses EFI boot.
