A customer has created a thin LUN, enabled compression on a LUN Pool, and installed their
Exchange environment. The Exchange application is showing poor performance. Which
workload characteristic of Exchange would produce poor access times on a compressed
LUN?

You are migrating a backup application that runs on physical servers to a VDC. The VDC
storage is currently a VNX configured with NL-SAS drives only. Your customer is concerned
about the cost to achieve reasonable performance. You are designing the VMs that will
support the application. Based on cost, which would be the first solution you would
recommend?

Your customer is designing a Proof of Concept with SQL Server attached to a VNX. The
storage design includes seven LUNs on a RAID Group. The system is generally very heavily
loaded, with a particularly high load on the cache. This is a very carefully controlled
environment and your customer has asked for assistance in planning the layout of the LUN
location on the physical spindles. Where in the RAID Group would you recommend placing
the two heavily used LUNs for a “short-stroked” architecture?

A customer is about to implement your VNX for File design for a file-sharing environment.
The design specifies both NFS and Windows clients that access file systems in a
multithreaded manner. All file systems will be created using the Automatic Volume Manager.
The customer is most concerned with disk efficiency, and wants to use all storage in each
pool entry before creating another.
Which value would you change to meet this requirement?

A VNX for File administrator is implementing SnapSure for backup staging. The
administrator is concerned that this solution might affect the Production File Systems (PFS).
You are asked to describe the possible performance impact of SnapSure checkpoints on the
PFS. How would you respond?

A customer is using a virtualized environment with a large number of NFS datastores
presented from a VNX system. They are experiencing more than expected network traffic on
their datastore networks. According to EMC best practices, what recommendation should
you make to your customer?

A customer with a virtualized environment has asked you to architect a new VNX storage
solution utilizing their many NFS datastores. They are also deploying a new Cisco Unified
Computing System as their compute base. However, they believe that virtualizing their
critical servers may cause network performance concerns because these servers have a
very high transaction rate with a CPU bound application. How would you respond to your
customer’s concerns?

Your customer is reporting less than optimal performance for their online payment
processing application. The payment processing application is running on a Windows Server
cluster with the back-end Oracle databases running on Oracle Enterprise Linux (OEL). Both
the application and database environments have been presented storage from the
customer’s VNX solution. Which tool is best suited to identify database performance issues?

A customer wants to mark an Incremental SAN Copy Session at 12:00 UTC, and start the
transfer of data at 20:00 UTC. Their data access pattern consists of small block I/O, with
around 80% reads.
Which statement correctly identifies the performance impact on their environment?

Exchange 2010 is being implemented on a pair of VNX storage arrays. There will be a
production site and a DR site, each with two servers and one VNX storage array. EMC
RecoverPoint will handle the remote replication between the sites.
Which is a valid architecture?
