| Which 3 VHD formats do you know? | - VHD - VHDX - VHD SET |
| What is the maximum size of a VHD disk? | 2040 GB |
| Which VHD format would you choose if you want to support older Hyper-V versions? | VHD |
| What is the maximum size of a VHDX disk? | 64 TB |
| Which VHD format would you choose, if you want to resize the virtual disk while the VM is running? | VHDX (connected to a SCSI controller) |
| Where is the VHD SET format used for? | It is used for shared VHDs |
| Which 2 tools can you use to convert between VHD and VHDX formats? | - Convert-VHD cmdlet - Hyper-V manager's edit virtual hard disk wizard |
| Can you convert the VHD SET format as well? | No, you can not convert the VHD SET format |
| Which VHD formats can you use with a generation 1 VM? | - VHD - VHDX |
| Which VHD formats can you use with a generation 2 VM? | - VHDX |
| Which 3 VHD types do you know? | - Fixed Size - Dynamically expanding - Differencing |
| Which tool can you use to convert between disk types? | The edit virtual hard disk wizard |
| Can you only use VHD and VHDX disk types within a VM? | No, you can also mount a disk with: - The disk management console - The diskpart command line tool - Powershell |
| Can you use a physical disk directly in a VM? | Yes, this is known as pass-through disk. You can use this to directly connect a: - iSCSI LUN - Physical hard disk that is connected to the host |
| When using pass-through disk, can the Hyper-V host and a VM use the same physical disk at the same time? | No, the VM must have exclusive access to the disk. |
| How does a VHD of a fixed size work? | It allocates all space immediately |
| How does a differencing disk work? | A differencing disk makes use of a parent-child relationship. The parent disk contains a sysprepped image. All changes are written to the differencing (child) disk. No changes to the parent disk occur. |
| How does a dynamically expanding disk work? | You specify a maximum size for the disk. The disk file only uses the space that it needs. |
