Which of the following file systems centralizes data and can be used to replicate shared folders to
other servers?

A.
ADFS

B.
FAT32

C.
DFS

D.
NTFS

Explanation:
DFS (Distributed File System) centralizes data and can be used to replicate shared folders to other
servers. Distributed File System (DFS) allows users to access files located on another remote host as
though working on the actual host computer. This makes it possible for multiple users on multiple
machines to share files and storage resources. The client nodes do not have direct access to the
underlying block storage but interact over the network using a protocol. Distributed file systems may
include facilities for transparent replication and fault tolerance. That is, when a limited number of
nodes in a file system go offline, the system continues to work without any data loss.

D is incorrect. NTFS is a high-performance file system proprietary to Microsoft. NTFS
supports file-level security, compression, and auditing. It also supports large volumes and powerful
storage solution such as RAID. The latest feature of NTFS is its ability to encrypt files and folders to
protect sensitive data.

A is incorrect. Active Directory Federation Services (ADFS) is used to extend the ability to
use single sign-on functionality to Internet-facing applications. With the help of single sign-on and
ADFS, a user can give their customers, partners, and suppliers easy access to Web based applications
in the organization, such as Outlook Web App.

B is incorrect. The FAT32 file system is an enhancement of the FAT file system. It is more
advanced and reliable than all the earlier versions of the FAT file system. It manages storage space
on large hard disks more efficiently than the FAT16 file system. It uses a smaller cluster size than the
FAT16 file system on the hard disk, thereby reducing the amount of space on the hard disk when
users save small files. The FAT32 file system supports hard disk drives larger than 2GB and up to 2TB.
