Answer : A

The Reserved Capacity for a Storage Resource Pool (SRP) on a VMAX3 has been set to
15%. A TimeFinder SnapVX snapshot has been created for a Storage Group containing 10 devices. An application is actively performing read and write I/Os to these devices. The snapshot is linked to the target in Copy mode. Allocation for the SRP reaches 85%.
What will happen to the copy process?

  • A. Copy to the target will halt
  • B. Copy to the target will fail
  • C. Tracks required for the copy will be allocated from the Reserved Capacity
  • D. Copy to the target will continue and complete


Answer : A

A storage administrator began taking nightly TimeFinder SnapVX snapshots of Oracle database LUNs 7 days ago. The administrator reports that the snapshots failed the previous night.
What advice should beprovided to the administrator?

  • A. Confirm there is available capacity in the Storage Resource Pool
  • B. Update the Solutions Enabler database and re-run the snapshots
  • C. Confirm the database was put in hot backup mode before the snapshot
  • D. Link the last good snapshot to a target and restore the database LUNs


Answer : A

What happens when SRDF/A DSE begins to spill tracks in VMAX3?

  • A. Uses SRP to offload the data from cache
  • B. Uses the DSE pool associated with the SRDF group
  • C. Uses the cache partition for the excess tracks
  • D. Throttles the host I/O to pace with the data transfer


Answer : A

A customer wants to know if they need to set the SCSI3_persist_reserve attribute for their
VMAX3 devices used in a clustered environment. Whatinformation should be provided?

  • A. All VMAX3 thin devices have the attribute enabled by default.
  • B. Attribute has been removed for VMAX3.
  • C. Attribute will need to be manually set for each device.
  • D. Attribute should not beused for clustered environments.


Answer : A

What is a valid RDF device pair state to invoke an SRDF suspend operation?

  • A. Synchronized
  • B. SyncInProg
  • C. Split
  • D. FailedOver


Answer : A

What is the effect of block size on responsetimes in an SRDF/S environment?

  • A. Larger block size applications experience higher response times.
  • B. Smaller block size applications experience higher response times.
  • C. Larger block size applications have the same response times as smaller block size applications.
  • D. Block size has no effect on response times.


Answer : A

A storage administrator wants to add new volumes to an existing VMAX3 Storage Group.
The new volumes need to have a different SLO than the existing Storage Group.
What will happen when the new volumes are added to the existing VMAX3 Storage Group?

  • A. New volumes will inherit the SRP and SLO set on the existing Storage Group.
  • B. Job to add the new volumes to the existing Storage Group will fail.
  • C. New volumes will retain the default SRP and SLO when they are added to the Storage Group.
  • D. Job to add the new volumes will issue a warning and then add the new volumes to the Storage Group.
