Your network consists of one Active Directory domain. All domain controllers run Windows Server
2008. You have file servers that run Windows Server 2008. Client computers run Windows Vista and
UNIX-based operating systems. All users have both Active Directory user accounts and UNIX realm
user accounts. Both environments follow identical user naming conventions. You need to provide
the UNIX-based client computers access to the file servers. The solution must meet the following
requirements:
• Users must only log on once to access all resources.
• No additional client software must be installed on UNIX-based client computers.
What should you do?
A.
Create a realm trust so that the Active Directory domain trusts the UNIX realm.
B.
Install an Active Directory Federation Services (AD FS) server that runs Windows Server 2008 R2
C.
Enable the subsystem for UNIX-based applications on the file servers. Enable a Network File
System (NFS) component on the client computers.
D.
Enable the User Name Mapping component and configure simple mapping. Enable a Network File
System (NFS) component on the servers.
Explanation:
To provide the UNIX-based client computers access to the file servers, you need to enable the User
Name Mapping component and configure simple mapping and also enable a Network File System
(NFS) component on the servers. User Name Mapping (UNM) bridges the gap between the different
user identification used in Windows and UNIX worlds. When UNM is used it in conjunction with
Server for NFS, UNM authenticates the incoming NFS access requests. With Client for NFS, it
determines the effective UID and GID to be sent with the NFS requests to UNIX NFS servers.
