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?

A customer plans to use Incremental SAN Copy (ISC) to migrate data between two EMC VNX.
They attempt to create a SAN Copy session from a source LUN, but are unable to create the
session. Which is the most likely cause for this SAN Copy session behavior?

How do primary and standby Control Stations monitor each other?

A customer configures an Incremental SAN Copy session between a 500 GB LUN and a 550 GB
thick LUN on a new DR VNX. The reserved LUN pool has 50 GB of free space. The source VNX
has registered with the DR VNX. The SAN Copy session does not start. What is the cause of the

issue?

A customer is implementing an Oracle database on an EMC VNX. Due to cost constraints, the
customer cannot dedicate physical disks for the redo logs. How can the disks be laid out to
reduce the probability of hitting the VNX write pending limit?

An EMC VNX with EMC FAST Suite will be used as block storage for four Exchange 2010 servers.
The Exchange servers will be used as mailbox and archive 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
The customer wants to implement auto-tiering. What do you advise the customer?
