A customer needs a RAID configuration that can maintain 500 host IOPs. The workload has a profile of 90% reads and 10% writes. The customer is also trying to reduce the amount of drives to buy. What RAID configuration would meet the customer's requirements?

• A.7.2K NL-SAS Drives in a RAID 6 2+2
• B.10K SAS Drives in a RAID 1/0 2+2
• C.7.2K NL-SAS Drives in a RAID 5 2+1
• D.10K SAS Drives in a RAID 1/0 1+1

A Customer is planning to build a VMware DTaaS environment on a VNX array. The customer is deciding what type of VM replicas would be acceptable in their environment. It needs to have a small footprint and contain frequently accessed data on SSDs drives. What should be recommended?

• A.Full clones
• B.Flash clones
• C.Link Clones
• D.Snap clones

You have designed an Auto-tiering solution using Flash, SAS, and NL-SAS disks in your storage pool. Your design was implemented and scheduling has been running daily. The customer reports that there is no data in the NL-SAS tier.
Why is this the case?

• A.Tiering is set up for Lowest Available Tier
• B.There was no data in the Flash drives to start with
• C.Data was previously moved to another tier
• D.Scheduling is not required for this configuration

A customer creates a multi-tiered pool with the following configuration:
-Five 200 GB FAST VP optimized Flash drives configured as 4+1 RAID 5 -Ten 600 GB 15 krpm SAS drives configured as 4+1 RAID 5 -Sixteen 2 TB NL-SAS drives configured as 6+2 RAID 6
The customer's workload consists of 4 kB random I/Os with a R/W ratio of 2:1.
How many host IOPs can the pool support?

• A.6,913 writes/s and 13,827 reads/s
• B.20,740 IOPs
• C.3,397 writes/s and 6,793 reads/s
• D.28,240 IOPs

Which naviseccli performance counter is used to view stripe boundary crossing statistics?

• A.getlun
• B.getdisk
• C.getrg
• D.getcontrol
