Hotspot Question
Your network contains an Active Directory domain named contoso.com.
The relevant servers in the domain are configured as shown in the following table.
You plan to create a shared folder on Server1 named Share1.
Share1 must only be accessed by users who are using computers that are joined to the domain.
You need to identify which servers must be upgraded to support the requirements of Share1.
In the table below, identify which computers require an upgrade and which computers do not require
an upgrade. Make only one selection in each row. Each correct selection is worth one point.
Answer: 
Explanation:
From this question it’s not clear (at first), what can you use to do that: Group Policy, certificates, DAC, but I think DAC is the answer. And I think the answer is correct. I post this comment in order to provide 2 useful links: https://technet.microsoft.com/en-us/library/dn408191.aspx

I saw many times wrong answers and links that point to older Windows Server versions, although in TechNet are available newer articles, for the most recent Windows Server version.
I think these links are helpful.
Thanks.
You need at least one DC that is 2012R2, and the FS needs to be 2012R2, so the given answer is correct.

I didn’t realize what was being asked at first. But DAC fits perfectly in “only computers joined to the domain”, since they must be receiving GPO and passing claims.
The answer is bullshit, since classic shares also would fulfil the requirements.
