• Question 58:

  You are implementing a Celerra CIFS solution. When discussing the mapping method choices, the site administrator asks you to explain the significance of the user mapping method for CIFS users. How do you respond to the site administrator?

  A. Celerra has a UxFS-based file system that requires UNIX style UIDs and GIDs for file and directory permissions. Windows users and groups are identified with SIDs. The mapping method correlates UNIX UIDs and GIDs to Windows SIDs for uniquely identifying users.
  B. Celerra has a UxFS-based file system that stores UNIX style UIDs and GIDs and Windows SIDs for file and directory permissions. The mapping method correlates the SIDs for local group permissions on the CIFS server shares.
  C. CIFS servers that join the Windows domain are assigned domain SIDs. The mapping method is used to uniquely identify the CIFS servers in the Windows AD domain to UNIX NFS servicers in the NIS domain.
  D. Stand-alone CIFS servers require a manual SID assignment when configured on a Celerra. When users from the Windows domain access the Celerra the mapping method correlates the stand-alone CIFS server SID with the Windows user SIDs.
  A. Celerra has a UxFS-based file system that requires UNIX style UIDs and GIDs for file and directory permissions. Windows users and groups are identified with SIDs. The mapping method correlates UNIX UIDs and GIDs to Windows SIDs for uniquely identifying users.
