Click on the calculator icon in the upper left-hand corner. A customer has a heterogeneous pool with the following configuration:
✑ 1000 GiB of Flash, with 400 GiB free
✑ 10,000 GiB of SAS, with 2,000 GiB free
✑ 80,000 GiB of NL-SAS, with 20,000 GiB free
The customer creates a new LUN with data placement policy set to "auto-tiering". The LUN is then populated it with 500 GiB of data. How will that data be distributed (numbers are approximate)?
300 GiB on Flash, 200 GiB on SAS, no data on NL-SAS
166 GiB on Flash, 166 GiB on SAS, 167 GiB on NL-SAS
9 GiB on Flash, 45 GiB on SAS, 446 GiB on NL-SAS
400 GiB on Flash, 100 GiB on SAS, no data on NL-SAS
You have completed collecting the host, network, and storage data for a design you are providing to a customer. What provides a simple method of processing the gathered data configuration?
E-Lab Support matrix
During a data gathering meeting with a customer, a discussion about applications was presented. Most of the applications are best suited for a RAID 5 pool on the VNX. However, one of the applications has an I/O requirement for RAID 1/0 spindles.How should the RAID 1/0 application requirement be handled?
Create two separate pools; one for RAID 5 and the other for RAID 1/0
Combine the RAID 1/0 with the RAID 5 into one pool
Create a large RAID 1/0 pool
Create a large RAID 6 pool
The CTO (Chief Technology Officer) of mid-sized company decided to virtualize their storage environment. From the interview, you learn that the company has strict performance requirements that must be met to create a successful solution. How should the performance requirements for the customer be determined?
On a server to server basis
Based on RAID and current LUN sizes
By gathering back-end IOPs
On an aggregate I/O basis
Your customer wants to increase the length SnapSure snapshots are being kept but is concerned about having the available capacity to extend the SavVol Space. The file system is currently 350 GiB in size and the SavVol is 20 GiB in size. By how much capacity will the SavVol be extended when the High Watermark is reached?
Refer to the exhibit.
While trying to maximize availability for CIFS clients, the customer has designed the following 10 Gb/s IP environment. What would you change in this design?
Ensure every connection has a failover to another switch.
Two Nexus switches are needed and the connection to the third switch removed.
Add three more connections to the VNX.
Change from LACP to Ether Channel for higher performance.
Upgrade to a VNX7500 to provide additional Data Movers.

A customer plans to deploy a VNX array to support their VMware View environment. They report 1000 Helpdesk users login daily at 08:00 and are concerned about the number of concurrent user logins causing performance slowdowns. Which VNX feature will address this concern?
Unisphere Quality of Service Manager
Refer to the exhibit.
A customer is analyzing the size of data sent to disk. Which command generated the output?
naviseccli -h spa getdisk
naviseccli -h spa getlun
A customer is using Unisphere Analyzer to view performance information for an existing VNX array. They are using Thick Pool LUNs for an Oracle ERP solution and are trying to determine FAST Cache usage for the LUNs, but the FAST Cache statistics are not being displayed. What do you advise them?
FAST Cache statistics are not available for Pool LUNs
Enable advanced checkbox in Analyzer settings
Restart statistics logging with FAST Cache checkbox enabled
Disable and re-enable FAST Cache to clear statistics
A customer plans to replace a CLARiiON CX4-960 with a new VNX system. The disks on the CX4-960 are all configured as RAID Groups. The new system will use Pools exclusively. Local replicas are made using SnapView Snapshots, and have required the use of Reserved LUNs with a total size of 10 TB. The customer wants to know if they should continue to use SnapView Snapshots, or should change to using VNX Snapshots. They want you to explain your answer. What do you tell the customer?
VNX Snapshots have a lower performance impact than SnapView Snapshots
SnapView Snapshots have a lower performance impact than VNX Snapshots
The Reserved LUN Pool required for VNX Snapshots will be smaller than that for SnapView Snapshots
VNX Snapshots will require an additional Pool for the redirected write data
Your customer has just purchased a new VNX, which will be dedicated to their large SQL 2008 cluster. High-performance and high-availability are critical.
To meet their availability requirements, the customer has requested the configuration be optimized to allow both storage processors to process I/O for any given LUN without trespassing the LUN. Which configuration best supports their availability requirements?
Failover Mode 4
Failover Mode 1
Failover Mode 2
Not supported on VNX platform
A customer has multiple VNX Unified storage systems. They are looking for a disaster recovery solution that makes efficient use of their limited bandwidth. What is a recommended RecoverPoint solution for this customer?
RecoverPoint/SE integrated with SRM
What controls the reporting of events when using Event Monitor?
Refer to the exhibit.
A customer has an existing CX4-480 that is more than three years old. You have been asked to review the array health and design a new VNX to replace the old array. Which performance issue is indicated by the heat map?
Write Cache is periodically full for one Storage Processor
Write Cache is periodically full for both Storage Processors
Front-end Fibre Channel port utilization is unbalanced
Too many pools have resulted in uneven extent distribution
Your customer's IT group configured a VNX array and created multiple RAID 5 (2+1) RAID Groups. They just realized their mistake and bought new drives. How would you bring the customer into compliance with EMC best practices with minimal impact?
Create RAID-5 (4+1) groups with new drives; migrate LUNs to new RAID Groups.
Use the new drives to expand existing RAID-5 Groups to RAID-5 (4+1) Groups.
Back up all data to tape; then destroy and re-create RAID Groups with RAID-5 (4+1) RAID Groups.
Buy a new VNX configured with RAID-5 (4+1) and use SAN Copy to migrate the data.

E20-324 VNX Solutions Design Exam for Technology Architects
~ 60 Questions
Specialist – Exam E20-324
This exam is one of two qualifying exams for the EMC Technology Architect for VNX Solutions – Specialist track.
This exam focuses on the knowledge and activities involved in approaching and executing the design process for VNX Unified storage environments. This include
understanding on gather, analyze, and interpret data from customer’s environment and design of the most appropriate solution based on VNX solutions design practices and considerations.
EMC provides free practice tests to assess your knowledge in preparation for the exam. Practice tests allow you to become familiar with the topics and question types you will find on the proctored exam. Your results on a practice test offer one indication of how
prepared you are for the proctored exam and can highlight topics on which you need to study and train further. A passing score on the practice test does not guarantee a passing score on the certification exam.
