On which volumes can you enable Data Deduplication?
Data Deduplication in Windows Server is supported on data volumes but not on system or boot volumes. Therefore, drives used for the operating system, such as the boot drive, are excluded. Typically, Data Deduplication can be enabled on NTFS and ReFS volumes starting with Windows Server 2019. Considering these requirements, volumes D and E are suitable for enabling Data Deduplication, assuming that neither of these volumes is used as the system or boot volume.
Wait! ReFS - Data Deduplication is supported starting with Windows Server 2019. From: https://docs.microsoft.com/en-us/windows-server/storage/data-deduplication/interop D E
More info why is D) D and E only You can't include C (Boot drive) https://docs.microsoft.com/en-us/previous-versions/windows/desktop/dedup/about-data-deduplication Deduplication is not supported on: System or boot volumes Remote mapped or remote mounted drives Cluster shared volume file system (CSVFS) for non-VDI workloads or any workloads on Windows Server 2012 Files approaching or larger than 1 TB in size. Volumes approaching or larger than 64 TB in size.
Got this question on 7/31/23. Didn't have the option to choose D and E only. I even left feedback that ReFS now supports Data Deduplication at the end of the exam. So, I just chose D only.
https://docs.microsoft.com/en-us/windows-server/storage/refs/refs-overview Functionality The following features are available with ReFS and NTFS: Feature ReFS NTFS BitLocker encryption Yes Yes Data Deduplication Yes1 Yes note 1 Available on Windows Server, version 1709 and later, Windows Server 2019 (1809) LTSC or later.
C and D is the correct answer because both of filesystem are NTFS
Agree! https://docs.microsoft.com/en-us/windows-server/storage/data-deduplication/understand File system The file system is the software and on-disk data structure that the operating system uses to store files on storage media. Data Deduplication is supported on NTFS formatted volumes.
Wrong. You cannot dedup the OS volume, only data volume. Thats why its called DataDedup!
C is boot vol. You cannot dedupe the boot vol. Common guys. Ez question.
Data Dedup is supported starting with Server 2019 but how do we know Server 2019 is being used here? Am I missing something?
Answer D. ''Data Deduplication is fully supported on Storage Spaces Direct with ReFS or NTFS-formatted volumes (mirror or parity). ReFS-formatted volumes are supported starting with Windows Server 2019. Deduplication is not supported on volumes with multiple tiers.''
Tricky question: Introduction blog post stands that OS is not supported: https://techcommunity.microsoft.com/t5/storage-at-microsoft/introduction-to-data-deduplication-in-windows-server-2012/ba-p/424257 Documentation for 2012 R2 stands that is not supported: https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/hh831700(v=ws.11)?redirectedfrom=MSDN#BKMK_Step1 New documentation "Data Deduplication interoperability" doesn't mention anything about the OS drive: https://learn.microsoft.com/en-us/windows-server/storage/data-deduplication/interop ChatGPT says that it is possible but not recommended. D and E
https://learn.microsoft.com/en-us/windows-server/storage/data-deduplication/interop Data Deduplication is fully supported on Storage Spaces Direct with ReFS or NTFS-formatted volumes https://learn.microsoft.com/en-us/previous-versions/windows/desktop/dedup/about-data-deduplication Deduplication is not supported on: System or boot volumes D is the answer
Answer is A. C & D Only
Wrong. You cannot dedup the OS volume, only data volume. Thats why its called DataDedup! So many of your answers are incorrect.
Data deduplication is not supported on boot or system drives: Deduplication was built for NTFS data volumes and it does not support boot or system drives
The kind of guys that show up at interviews with a Cert but cannot for their life answer a few simple questions about the area.
C and D because both of filesystems are NTFS
