Virtual machine storage

Question

You administer a server that runs Windows Server 2012 R2 with the Hyper-V role installed. You plan to deploy a new virtual machine (VM to the server. The data stored by the VM doubles each month. You have the following requirements: - The virtual hard disk (VHD) must minimize the storage space requirements. - Changes to the VHD must NOT require user intervention. You need to create the VHD. What should you create?

Options

  • Aa dynamically expanding file that uses the VHD file format
  • Ba file that uses the VSV file format for the data LUN
  • Ca differencing file that uses the VHD file format
  • Da differencing file that uses the VHDX file format

Explanation

A differencing disk has a link to a parent disk. So you always have 2 disk's. The parant disk white the actuale size + the differencing disk white al the delta data. As data are written into a Dynamic VHD, the total size of the VHD will grow accordingly -VHD (30GB) + differencing disk (from 0GB to 30GB) = min 30GB, max 60GB -VHD dynamic (30GB) = min 0GB, max 30GB
