Question No. 5

Which of the following smb.conf options turns a regular file share into a DFS share?

Show Answer Hide Answer
Correct Answer: A

DFS (Distributed File System): This allows for the organization of shared files on multiple servers in a distributed file system.

msdfs root = yes: This option in the Samba configuration file (smb.conf) enables a share to be a DFS root. This means the share can provide access to multiple other shares possibly located on different servers, creating a single point of access.

Functionality: When enabled, users accessing this DFS root can be redirected transparently to the actual location of the shared files, which might be spread across different servers.

Setup: To configure a DFS root, add msdfs root = yes to the specific share definition in smb.conf.
