Free Access Netapp NS0-155 New Release

http://www.ntapgeek.com/2011/03/netapp-storage-encryption-available.html

March, 2011: "With the recent release of Data ONTAP 8.0.1, NetApp now offers full disk encryption to prevent unauthorized access to data at rest."

Data OnTap can simultaneously serve NAS and SAN protocols. CIFS, NFS, and FC protocol are examples of NAS and SAN protocols respectively.

Data OnTap 7.1 or later does not support DAFS.

DFS provides location transparency and redundancy by allowing shares in multiple different locations to be logically grouped under one folder, or DFS root. While practically a CIFS server shared by a Data OnTap filer can be a DFS target, DFS namespaces can only be hosted on Windows systems.

In order to test or effect a Disaster Recovery operation, you must restrict access to the disaster site node to prevent the node from resuming service. If you do not, you risk the possibility of data corruption.

Access to the disaster site note can be restricted in the following ways:

Turn off the power to the disaster site node Use "manual fencing" (Disconnect VI interconnects and fiber channel cables; either physically or through configuration changes on the fabric switches.)

Isolating the failed node from the surviving node could still lead to the possibility of a split brain, so this is not a correct answer.
