Exam 70-740 topic 1 question 110 discussion

Process of elimination... Answer A is out because you can't run dedupe on the OS volume Answer B is out because you can't run dedupe on exFAT Answer C is correct, there is nothing that can preclude you from running Dedupe on this volume Answer D - Technically correct as of Update 1709 Answer E - is correct as nothing on this volume prevents you running dedupe. So you should choose Answers C and E (volumes E and G). DO NOT CHOOSE Answer D (Volume F) as this is only correct as of 1709, you don't know which answer the question is looking for an whether or not MS have updated the answer so you do not know if it will allow it. We do know that regardless of version answers C and D are correct.

Made a mistake, in the above reply the very last line should read... C and E are correct. Sorry about that.

Option A is wrong as the OS would be on C:. Option B and D are wrong as prior to 1709, ReFS was not supported and exFAT was never supported. That leaves Options C & E as the correct answers.

What should we answer in the exam? Obviously ReFS already supports data dedup after 1709...?

IMPORTANT: ReFS already supports deduplication as of version 1709. This answer is out of date! In the exam you MUST consider the upgrade.

Although the exam may say that ReFS does not support data deduplication, After Windows Server 2016 version 1709 ReFS does support deduplication. https://docs.microsoft.com/en-us/windows-server/storage/refs/refs-overview

i know refs can run data deduplication , can anybody explain why the answer scape the refs??
