Which type of file system enables an administrator to configure a vDisk with a size of approximately 2TB?

Orla P.Jan 10, 2026

The answer is D, NTFS. When Citrix Provisioning Services stores a vDisk, it writes it as a large file on the host file system, and that host file system has to be able to handle a file that big. FAT and FAT32 cap individual file sizes at 4 GB, so a 2 TB vDisk image is completely out of the question for those. ext2 is a Linux file system and does not apply in the Windows-based PVS store scenario the exam is testing, and VHD is a disk image format, not a file system at all. NTFS supports individual file sizes well beyond 2 TB, which is exactly why it is the only option on this list that actually works as the underlying file system for a vDisk that large.

NTFS is the right answer here because it supports volumes and files well over 2TB, making it the only realistic choice for a vDisk that size. FAT tops out way too low, ext2 is Linux-based and not relevant in a Citrix XenApp context, and VHD is a disk format, not a file system.

So I got this one wrong the first time because I kept thinking about the vDisk format itself rather than where the vDisk file actually lives on the store. My senior walked me through it and pointed out that FAT32 has a 4GB ceiling per file, so a 2TB image would never even fit on that volume, full stop. ext2 is Linux territory and Provisioning Services is not going to be dropping a .vhd on an ext2 share, so that's out too. VHD is the container format for the vDisk itself, not the underlying file system hosting it, which is a distinction the exam loves to test. That leaves NTFS, which handles files well into the terabyte range and is exactly what the PVS store needs to hold a vDisk that large, so D is the pick. Here is my genuine question though: if the store is on a network share like a Windows file server, does NTFS on the share volume give you the large-file support, or does it depend on how the share protocol (SMB version or something) presents the volume to the PVS server? I want to make sure I am not just memorizing "NTFS equals big files" without understanding where in the stack that limit actually lives.

I actually leaned toward VHD first because we talk about vDisk containers so often in PVS that the format question felt like a trick pointing at the container type, but the real constraint is the store file system sitting underneath it, and FAT32 caps individual file sizes at 4GB while NTFS handles the multi-terabyte range you need for a roughly 2TB vDisk image on the server store.

Section 3 of the 1Y0-A06 blueprint covers vDisk creation and storage configuration, and the mnemonic I give my students is "New Technology = No Terabyte ceiling," tying NTFS to its ability to handle volumes far beyond the 4 GB wall that kills FAT or the Linux-only scope of ext2. The answer is D, NTFS, because VHD is a container format and not a file system, FAT tops out at 4 GB per file, and ext2 has no role in a Windows-based Provisioning Services store. I remember sitting that exam and seeing this exact question, pausing for a second because VHD looked tempting given we were talking about virtual disks, then catching myself and circling back to the underlying file system the store volume itself has to use, which has to be NTFS to hit that 2 TB vDisk size.

Quick win, grab those 2 points and move on. The 2TB ceiling is the giveaway here because FAT tops out around 4GB per file and has a 32GB volume limit on most implementations, ext2 is Linux and has no business on a Citrix vDisk question, and VHD is a container format for virtual hard disks, not a file system itself. NTFS is the only option that handles volumes well above 2TB, making it the obvious choice for large vDisk configurations in a Provisioning Services environment. When I sat for this one, I flagged it out of habit but came back to it and knew immediately, took maybe 8 seconds total and the 2TB number pointing straight at NTFS felt like a gift from the exam writers.
