You have performed a Data Mover failover test, and now CIFS shares and NFS exports are unavailable. You cannot ping or tracert to their assigned IP interfaces.
What networking configuration issue could be causing this problem?

• A.  Switch ports connecting the standby Data Mover are not on the same VLAN as the primary.
• B.  Dynamic DNS is configured to use UDP.
• C.  The VLAN tagging for the interfaces on the standby Data Mover is incorrect.
• D.  NFS and CIFS protocols are not started on the standby Data Mover.

An administrator needs to configure a network trunk on a Data Mover using the command:
server_sysconfig server_2 -virtual -name trk0_la -create trk -option "device=cge2,cge3 protocol=lacp
What additional option is used to add statistical load distribution to the trunk configuration?

• A.  lb=mac
• B.  -o start
• C.  -o mac
• D.  lb=on

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.  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.
• B.  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.
• C.  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.
• D.  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.

What application provides integration between the Celerra and the iSCSI host for replicating an iSCSI LUN?

• A.  Navisphere Manager
• B.  Unisphere Manager
• C.  Replication Manager
• D.  Celerra Manager

Which Celerra feature stores Windows SIDs correlated to UIDs and GIDs?

• A.  ntxmap
• B.  SavVol
• C.  NASDB
• D.  secmap
