A customer has successfully set up a MirrorView/A connection between two VNX arrays. After
selecting a traditional LUN as the primary image LUN, the user receives an error when trying to
add a secondary thin LUN image. What must the customer do to correct this problem?

A customer is using SAN Copy to migrate data between two EMC VNX. They use Navisphere
Secure CLI to manually select the source and destination LUNs for the SAN Copy session. The
source LUN is 419430400 blocks in size, with 367001600 blocks used for data. They select a
destination LUN that is 367001600 blocks in size. The SAN Copy session starts, but fails to
complete. What is the most likely cause for this SAN Copy session behavior?

A storage administrator recently replaced their secondary EMC CLARiiON with a new EMC VNX.
The secondary CLARiiON was used to store secondary images of their production LUNs using
MirrorView/S.
After the replacement, the storage administrator realizes they fractured the mirrors to the primary
CLARiiON, but did not destroy them. The storage administrator reports they are not able to
destroy the old mirrors and receives an error message stating the secondary SP cannot be
reached.
What is the recommended method to destroy the old mirrors?

A customer wants to implement file system replication between two EMC VNX. The source
production file system contains data from a sequential workload that resides in a pool comprised
of 2 TB NL-SAS drives. Due to cost concerns, the destination file system and SavVol volumes will
also be NL-SAS and share spindles with user LUNs for another application. What should you tell
the customer about this configuration?

A customer plans to migrate their virtualized server environment to a new VNX array. They are
concerned their storage pool configuration could be compromised by their varied server workload
profiles. What vSphere v5.0 feature would you discuss with the customer to address their
concern?

A customer recently installed vSphere ESXi 5.0 on a five host cluster attached to an EMC VNX
using FCoE. EMC PowerPath/VE with a full license is installed on all hosts in the cluster. What is
the default load balancing policy that will be used?

A customer is running a cluster of ESX v4.x servers accessing a VNX LUN with a very large
number of virtual machines. They are experiencing intermittent transaction acknowledgement
delays. What would you recommend to the customer to lessen these delays?

You review a Unisphere Analyzer report from a customer’s EMC VNX. You observe that disk read
activity is higher than can be accounted for from host reads and normal pre-fetch activity.
What is the likely cause?

A customer plans to use MirrorView/A to replicate between two VNXs communicating directly with
each other. The VNX are 160 kilometers apart. The customer cannot purchase a dedicated fiber
cable between sites or any additional hardware. What protocol should be used between sites?

A customer has an EMC VNX with the total efficiency pack. Several applications access the VNX
including the company’s Exchange 2010 email system. The Exchange log files are on a dedicated
RAID 1/0 LUN and the mailbox databases are on a storage pool shared by other applications.
What can be done to improve performance in the Exchange environment?
