• Question 43:

  What steps should you perform to create a copy of a source LUN in a second storage array, while minimizing unavailability of the source LUN?

  A. take a snapshot of the source LUN, then use SAN Copy to copy the snapshot to the second storage array

  B. take a snapshot of the source LUN, then use SAN Copy to copy the source LUN to the second storage array

  C. take a snapshot of the source LUN, runMirrorView to mirror the snapshot to the second array, then use SAN Copy to synchronize the mirror with the source LUN
