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 accessbased enumeration and use DFS Replication.

B.
Deploy a standalone DFS namespace. Enable accessbased enumeration and use File Replication Service (FRS).

C.
Deploy a domainbased DFS namespace and use DFS Replication. Modify each share to be a hidden share.

D.
Deploy a domainbased DFS namespace and use File Replication Service (FRS). Modify each share to be a hidden share.

MCITP Self-Paced Training Kit Exam 70-646 Windows Server Administration:

Distributed File System (DFS)
DFS is considerably enhanced in Windows Server 2008. It consists of two technologies, DFS Namespaces and DFS Replication, that you can use (together or independently) to provide fault-tolerant and flexible file sharing and replication services.

DFS Namespaces lets you group shared folders on different servers (and in multiple sites) into one or more logically structured namespaces. Users view each namespace as a single shared folder with a series of subfolders. The underlying shared folders structure is hidden from users, and this structure provides fault tolerance and the ability to automatically connect users to local shared folders, when available, instead of routing them over wide area network (WAN) connections.

DFS Replication provides a multimaster replication engine that lets you synchronize folders on multiple servers across local or WAN connections. It uses the Remote Differential Compression (RDC) protocol to update only those files that have changed since the last replication. You can use DFS Replication in conjunction with DFS Namespaces or by itself.

This lesson summarizes DFS only very briefly as part of your planning considerations. Lesson 2 of this chapter discusses the topic in much more depth.

Exam TipPrevious Windows Server examinations have contained a high proportion of DFS questions. There is no reason to believe 70-646 will be any different.

You can also use Share And Storage Management to view and modify the properties of a shared folder or volume, including the local NTFS permissions and the network access permissions for that shared resource. To do this you again select the shared resource on the Shares tab and select Properties in the Actions pane. Figure 6-6 shows the Properties dialog box for the share folder Public. The Permissions tab lets you specify share and NTFS permissions. Clicking Advanced lets you configure user limits and caching and disable or enable access-based enumeration (ABE). ABE is enabled by default and lets you hide files and folders from users who do not have access to them.
