You are an Enterprise administrator for contoso.com. The company has a head office and a branch office. All the servers in the network run Windows Server 2008 and all client computers run Windows Vista. Each office has a domain controller and file servers.
You have been asked to plan the deployment of Distributed File System (DFS) on the network and ensure that users can access the data locally and are allowed to see only the folders to which they have access permissions. You also need to ensure the use of minimum bandwidth while data replication.
Which of the following options would you choose to accomplish the desired task?
A.
A stand-alone DFS namespace that uses DFS replication and has access-based enumeration enabled
B.
A stand-alone DFS namespace that uses File Replication Service (FRS) and have access-based enumeration enabled
C.
A domain-based DFS namespace that uses File Replication Service (FRS) and modify each share to be a hidden share
D.
A domain-based DFS namespace that uses DFS replication and modify each share to be a hidden share
E.
None of the above
Explanation:
To plan the deployment of Distributed File System (DFS) on the network and ensure that users can access the data locally and are allowed to see only the folders to which they have access permissions, you need to deploy a stand-alone DFS namespace and has access-based enumeration enabled.
Rather than having every user in your organization access their files from the same server, you can distribute the user workload across multiple DFS replicas rather than over burdening a single server.
Standalone namespaces do allow you to use multiple folder targets for fault tolerance purposes. In case you are not familiar with folder targets, the basic idea is that each folder target typically hosts a replica of the data that’s associated with a DFS folder. Using multiple folder targets allows you to achieve a degree of fault tolerance, and offers better performance than if the data were only stored in a single location.
Domain-based DFS namespace requires an Active directory domain, which is not available here.
Access-based enumeration allows users to see only files and folders on a file server to which they have permission to access. This feature is not enabled by default for namespaces (though it is enabled by default on newly-created shared folders in Windows Server2008), and is only supported in a DFS namespace when the namespace is a standalone namespace hosted on a computer running Windows Server2008, or a domain-based namespace by using the Windows Server2008 mode.
