  • B. space-optimized instant snapshots
  • C. third-mirror break-off snapshots
  • D. linked break-off snapshots
Answer:

D

the data volume. This makes linked break-off snapshots especially suitable for recurring off-host
processing applications as it avoids the disk group split/ join administrative step
