Which disk type will always be created for each virtual machine, when creating new virtual machines using Machine Creation Services (MCS)?

Question

Options

• APersonal vDisk
• BDifferencing (Diff) disk
• CIdentity disk
• DFull-clone base disk

• A
  4% (1)
• C
  92% (24)
• D
  4% (1)

Explanation

When MCS provisions virtual machines, it always creates an Identity disk for every VM it deploys. This small disk (~16MB) stores each machine's unique identity - including its computer account credentials and SID - allowing cloned VMs to authenticate independently to Active Directory even though they all share the same master image.

Why the distractors are wrong:

• A. Personal vDisk - A legacy Citrix feature for user-layer personalization; it is optional, deprecated, and not created by default for every MCS VM.
• B. Differencing (Diff) disk - While diff disks exist in some MCS thin-clone architectures to track changes from the base image, they are not universally created in all MCS deployment types and are not the defining artifact.
• D. Full-clone base disk - Created only in full-clone MCS configurations, not in every MCS deployment scenario.

Memory tip: Think of the Identity disk as each VM's "ID card" - just as every person needs a unique ID to prove who they are, every MCS-provisioned machine needs an Identity disk to prove its unique identity to the domain, regardless of how the storage is configured.
