During a host write to an EMC VNX with write cache enabled, at what point does the host receive
acknowledgement from the VNX that the write is complete?

A customer runs their virtual environment on a cluster of ESX v4.0 hosts connected to an EMC
VNX. They report there are long delays when they create large eager-zero thick virtual disks.
You recommend they upgrade their virtual environment to vSphere v5.0 to benefit from its VAAI
features. Which VAAI primitive addresses their issue?

A customer is migrating an Oracle database to a new EMC VNX. The database consists of
random, small I/O workloads with high transaction rates.
What RAID type should be used for the LUN containing the data files in order to prevent I/O
bottlenecks during peak load?

When setting up an AVM created file system, the storage administrator set the “is_greedy” option.
When they look at the underlying structure of the newly created file system, they notice the file
system is sliced. What is the reason for this behavior?

When creating a clone, what size must the clone be when compared to source LUN?

Six months ago, you implemented an SQL 2008 database and followed EMC best practices for
sizing and layout. The database is now experiencing performance slowdowns. You configure
Perfmon to capture “disk bytes per second”, “average disk queue length”, and “percent disk time”

in a log view for the database volumes. The log shows the disk bytes per second remained steady
but there was an increase in the average disk queue length.
Which action should you take to solve this problem?

An EMC VNX is enabled for FAST Cache using four 200 GB Flash drives. Ten additional Flash
drives are available for SQL databases. Which SQL database object would be best suited to utilize
these drives?

An EMC VNX with FAST Suite will be used as block storage for a mail environment with four
Exchange 2010 servers. The Exchange servers will serve as mailbox and archive mailbox
servers. The VNX has the following disks in two DAEs:
– Five 200 GB Flash drives
– Fifteen 600 GB SAS drives
– Ten 2 TB NL-SAS drives
What storage pool design will provide balance between performance and storage provisioning?

A customer plans to add a new LUN to a Windows 2003 server. They are aware that LUN disk
crossing will affect performance. Which procedure can significantly reduce LUN disk crossings in
an SQL environment?

A VNX customer has a production read-intensive Oracle environment that requires immediate
access for end-user reporting. Which EMC replication application meets the customer’s business
requirement?
