Your company has a main office and two branch offices. Each office has a domain controller and file servers. Your network consists of a single Active Directory domain. All servers run Windows Server 2008 R2.
You need to plan the deployment of Distributed File System (DFS) to meet the following requirements:
Ensure that users see only the folders to which they have access.
Ensure that users can access the data locally.
Minimize the bandwidth required to replicate data.
What should you include in your plan?
A. Deploy a standalone DFS namespace. Enable Access-based enumeration and use DFS Replication.
B. Deploy a standalone DFS namespace. Enable Access-based enumeration and use File Replication Service (FRS).
C. Deploy a domain-based DFS namespace and use DFS Replication. Modify each share to be a hidden share.
D. Deploy a domain-based DFS namespace and use File Replication Service (FRS). Modify each share to be a hidden share.
Correct Answer: A
Explanation/Reference:
DISTRIBUTED FILE SYSTEM
Access-based enumeration (ABE) hides files and folders that users do not have permission to access. By default, this feature is not enabled for DFS namespaces. To enable ABE of DFS Namespace, DFS Management snap-in (available in 2008 R2 or above) or dfsutil command can be used.
To enable ABE of individual shared Folders, Share and Storage Management snap-in can be used.
To enable ABE on a namespace, all namespace servers (standalone or domain-based) must be running Windows Server 2008 or newer. Additionally, domainbased namespaces must use the Windows Server 2008 mode.
DFS Replication is an efficient, multiple-master replication engine that you can use to keep folders synchronized between servers across limited bandwidth network connections. It replaces the File Replication Service (FRS) as the replication engine for DFS Namespaces, as well as for replicating the Active Directory Domain Services (AD DS) SYSVOL folder in domains that use the Windows Server 2008 domain functional level.
DFS Replication uses a compression algorithm known as remote differential compression (RDC). RDC detects changes to the data in a file and enables DFS Replication to replicate only the changed file blocks instead of the entire file (FRS).
