Your network contains two Active Directory forests named contoso.com and adatum.com. All
servers run Windows Server 2012 R2.
A one-way external trust exists between contoso.com and adatum.com.
Adatum.com contains a universal group named Group1. You need to prevent Group1 from being
used to provide access to the resources in contoso.com.
What should you do?
A.
Modify the Managed By settings of Group1.
B.
Modify the Allowed to Authenticate permissions in adatum.com.
C.
Change the type of Group1 to distribution.
D.
Modify the name of Group1.
Explanation:
* Accounts that require access to the customer Active Directory will be granted a special right called
Allowed to Authenticate. This right is then applied to computer objects (Active Directory domain
controllers and AD RMS servers) within the customer Active Directory to which the account needs
access.
* For users in a trusted Windows Server 2008 or Windows Server 2003 domain or forest to be able
to access resources in a trusting Windows Server 2008 or Windows Server 2003 domain or forest
where the trust authentication setting has been set to selective authentication, each user must be
explicitly granted the Allowed to Authenticate permission on the security descriptor of the computer
objects (resource computers) that reside in the trusting domain or forest.
same like 379, but other answers.
C. Try to use distrigution group to provide access to for example share in your own domain, without any cross domain relations. It will not do.
Distribution Groups cannot be used to grant access permission, they are only used for email “distribution” lists.
