A VMAX3 storage administrator notices that some devices have different FA addresses on different ports within the same Masking View. Which setting could havebeen used to avoid this issue?

• A.Dynamic LUNs
• B.Consistent LUN
• C.SPC2 Port Flag
• D.Cascaded Storage Groups

You need to model several SRDF/A workloads that require data consistency across all sessions. How should the multiple SRDF/A sessions be modeled?

• A.Use SymmMerge and link SRDF/A sessions by creating a Composite Group
• B.Use BCSD and link SRDF/A sessions by creating a Composite Group
• C.Use SymmMerge and link SRDF/A sessions by creating a Logical Relationship
• D.Use BCSD and link SRDF/A sessions bycreating a Logical Relationship

A VMAX3 Storage Group has Host I/O limits set at 10,000 IOPs. The Port Group contains four ports across different directors. The Dynamic Distribution is set to "Always".
What is the maximum IOPs the Storage Group can achieve in the event a switch port being used by one of the director ports fails but the director remains online?

• A.10,000
• B.9,000
• C.5,000
• D.7,500

What does it mean if a Storage Group is listed as "Critical" in Unisphere for VMAX?

• A.Storage Group performance is below the SLO target
• B.Storage Group available capacity is running low
• C.Storage Groups belong to an SRP which is running low on space
• D.Hardware fault is impacting the Storage Groups

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

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