A Hyper-V VM to upload to Azure has these properties: Generation 1, dynamically expanding disk, VHDX format, 2 TB disk. Which two actions should you perform before uploading? (Choose two.)

Azure currently supports Generation 1 and Generation 2 VMs, but for Generation 1 VMs, the virtual hard disk must be in VHD format and fixed-size. The original VHDX format and dynamically expanding disk type are not directly supported for uploading a Generation 1 VM to Azure. Therefore, changing the disk type to fixed and the disk format to VHD are necessary pre-upload steps. Decreasing the disk size to 1 TB is not required as Azure supports VHDs up to 2 TB for Generation 1 VMs. Changing the disk type to differencing is incorrect as differencing disks are not directly uploaded; the parent disk would need to be uploaded. Changing the VM generation to Generation 2 would require a full rebuild or conversion process, which is more complex than simply adjusting the disk properties.
