As a result of suffering a catastrophic failure, your customer has requested a DR solution.
The solution must introduce a higher level of availability for their Exchange 2010 system.
The customer wants a strategy that involves Replication Manager and DAG with third-party
replication enabled. In what state(s) of the database would the replication occur?

A customer has recently implemented Microsoft Exchange 2010 on a VNX storage system
that hosts a variety of application servers. The Exchange implementation is currently using
RAID 5 (4+1) and uses FAST Cache for the database volumes, but is not using FAST VP.
Performance has been significantly diminished.
What would you recommend to the customer?

A clone source LUN is 512 GiB in size. It performs 500 random 8 KiB IOPs with a 3:1 R/W
ratio. As part of ongoing testing, the clone is fractured for 10 minutes and then
resynchronized. The testing is performed every hour.
How much data (to the nearest GiB) is read from the source LUN as part of the
resynchronization process?

A customer with an existing VNX for File implementation wants to enable deduplication on a
file system, based on the following specifications:
Idle File System
Number of files: 1 M
Average file size: 50 KiB
Estimated deduplication: 30%
What is the estimated time for initial deduplication?

A customer has a VNX system to provide storage for a VMware 4.1 Cluster with 4 ESX
hosts. MS Exchange servers and other application servers will be hosted on VMs. The
customer wants to have the best performance at the VMFS disk/volume level. What would
you recommend when creating boot and email stores using the Virtual Infrastructure client?

You are working with a customer that recently refreshed their hardware with a VNX storage
system configured with Flash drives. During this swap customer also migrated their
Exchange 2010 environment to the VNX. Now the customer is claiming that they do not see
any performance improvement with their Exchange environment.
What is your explanation?

A company recently purchased a VNX storage system to support its clustered SQL Server
environment. You are designing the disk layout.
Based on EMC best practices, what design characteristics should you follow when
configuring SQL Server on the VNX?

A customer is migrating an application to a virtualized environment. After the implementation
is completed they realize that performance is below their expectations.
You are tasked to investigate and recommend an economical solution. Using VMware Tools
and Analyzer on the VNX, you conclude that their application servers are experiencing CPU
over-utilization and storage connection congestion.
What should be your first recommendation?

You have designed a VNX for File solution for a creative content provider. The solution
involves 10, 2 TiB file systems. Each file system has a Checkpoint taken every hour,
refreshed every day. The customer predicted a 2% daily change rate, and SavVol storage
was allocated based on that change rate.
Sometime after the implementation, the customer notices that some of the older
Checkpoints are disabled.
What is the most likely explanation?

Your customer recently upgraded their IP switch hardware. Since the upgrade, the customer
is experiencing performance degradation on certain NFS exports configured on a VNX for
File storage system. The file systems providing the problem exports are all mounted to
DataMovers that have been attached to ports on the new switches as part of the upgrade.
They have engaged you for advice. Which action would you recommend?
