An architect plans to implement SRDF/A Legacy mode. What is a possible reason to do this?

• A.Decoupled cycle switching between R1 and R2 arrays
• B.Coupled cycle switching between R1 and R2 arrays
• C.Increased robustness of SRDF/A sessions and reduced DSE spillover
• D.More granular and predictable RPO at the R2 side.

How do Copy mode linked targets and NoCopy mode linked targets behave when a SnapVX unlink operation disassociates the linked target?

• A.Once the copy completes, Copy mode linked targets will contain a full and usable copy of the source devices.NoCopy mode linked targets will not allow access to unlinked targets.
• B.Once the copy completes, Copy mode linked targets do not contain a full and usable copy of the source devices.
  Behavior of NoCopy mode linked targets depends on the operating system running on the array. PowerMaxOS 5978 and HYPERMAX OS 5977.810.184 and later allow access to unlinked targets.
• C.Once the copy completes, Copy mode linked targets contain a full and usable copy of the source devices.
  Behavior of NoCopy mode linked targets depends on the operating system running on the array. PowerMaxOS 5978 and HYPERMAX OS 5977.810.184 and later allow access to unlinked targets.
• D.Once the copy completes, Copy mode linked targets contain a full and usable copy of the source devices.
  Behavior of NoCopy mode linked targets depends on the operating system running on the array. PowerMaxOS 5978 and HYPERMAX OS 5977.596.583 and later allow access to unlinked targets.

At a disaster planning meeting, an architect is presented with the following facts by a client:
A Unix host is replicating storage from a Production PowerMax to a VMAX 250FX.
RDF pairs have been split with Production and DR hosts accessing their respective storage.
Invalid tracks have started to build against PowerMax and VMAX 250FX.
The client now wants to bring production back to PowerMax, discarding the VMAX 250FX updates while keeping the updates on the PowerMax. What is the correct action to take?

• A.Resume
• B.Failback
• C.Establish
• D.Failover

Which formula is used to calculate the Data Reduction Ratio?

• A.Subscribed Allocated + (Modified NonShared / User Used)
• B.Snapshot Total + (Subscribed Total / User Used)
• C.Subscribed Allocated / (Modified NonShared + User Used)
• D.Snapshot Total + (Subscribed Allocated / User Used)

A storage administrator uses Unisphere for PowerMax to provision new storage from a VMAX All Flash array. Which Workload Type is recommended for a combination of small and large block I/O workloads?

• A.None
• B.OLTP
• C.DSS
• D.Optimized
