ONTAP SAN implementation and configuration

An administrator must ensure that Snapshot copies of database files spanning multiple FCP LUNs are captured at the same point in time.

Which two configurations allow the administrator to accomplish this?

Choose two
  • A Create a consistency group that uses FlexGroup volumes.
  • B Create each LUN within the same FlexGroup volume.
  • C Create each LUN within the same FlexVol volume.
  • D Create a consistency group that uses FlexVol volumes.
Explanation

A Snapshot copy is a point-in-time image of an entire volume, so all database LUNs within one FlexVol volume are captured together. When the LUNs span multiple FlexVol volumes, an ONTAP consistency group coordinates snapshots across the member volumes with a write fence, providing a consistent point-in-time image. ONTAP consistency groups support FlexVol volumes.
