Your network contains a domain-based Distributed File System (DFS) namespace named \\contoso.com\dfs. \\contoso.com\\dfs is configured to use Windows 2000 Server mode. The domain contains two servers named Server1 and Server2 that run Windows Server 2008 R2. Server1 is configured as a namespace server for \\contoso.com\dfs. You need to migrate \\contoso.com\dfs to Windows Server 2008 mode. You install the Distributed File System role service on Server2. What should you do next?
A.
Configure Server2 as a namespace server for \\contoso.com\dfs.
B.
At the command prompt, run dfsutil root export \\contoso.com\dfs c:\dfs.xml.
C.
At the command prompt, run dfsutil root adddom \\contoso.com\dfs v2.
D.
Create a new shared folder named DFS on Server2.
The Windows Server 2008 mode for domain-based namespaces includes support for access-based enumeration and increased scalability.
To migrate a domain-based namespace from Windows 2000 Server mode to Windows Server 2008 mode, you must export the namespace to a file, delete the namespace, recreate it in Windows Server 2008 mode, and then import the namespace settings. To do so, use the following procedure.
