VNX Solutions Expert Exam for Technology Architects: E20-880

Your customer has recently purchased a VNX to host their three Oracle RAC database environments and automated payment processing application. The RACs and application are differentiated as follows: ORA- PROD, ORA-STAGE, ORADEV, APP-PROD, APP-STAGE, and APP-DEV.

The customer has provided you with their Enterprise Storage Policy (ESP) and is requesting that you adhere to this policy when architecting their new VNX solution. The ESP states the following as it relates to Oracle database storage requirements:

All LUNs must be configured as raw devices

All LUNs must be managed using ASM

No fewer than two LUNs per ASM disk group

No more than one database per RAC per RAID Group

No more than three databases per RAID group

All data LUNs must be 1000 GiB RAID 5

All FRA LUNs must be 500 GiB RAID 1/0

No more than eight total disks per RAID Group

No fewer than four disks per RAID Group

Based on the ESP, and assuming ORA-PROD has six instances, what is the minimum number of RAID Groups required?

A. 1

B. 2

C. 3

D. 6

A customer asks about the High Bandwidth option for a data warehousing application. The customer would like to know the benefits of implementing this feature. How do you respond?

A. Increased queue depth and increased stripe element size

B. Symmetric Active/Active and increased queue depth

C. Increased Full Stripe Writes (FSW)

D. Increased random, small-block read performance

A customer is interested in implementing SSDs to improve response time for a sensitive database that generates mostly small random reads. The compute platform for this customer is Cisco UCS with on-board SSDs, which are not being utilized at this time. The customer asks which EMC product could help leverage their existing assets?

A. XtremSW

B. XtremSF

C. FAST Cache

D. PowerPath/VE
