A customer plans a DR test for their CIFS DR solution using EMC VNX. The customer needs to
confirm users will be able to access data at the DR site in the event of a source site disaster. The
VNX at the source site will not be shut down during the DR test. The customer asks how they
should proceed. What do you advise the customer?

A customer plans to implement shared vSphere datastores using the NFS protocol in their
environment. Their VMware support staff has concerns about their administration of these
datastores. What features of vSphere v5 would you discuss with them to address their concerns?

A customer has the following virtualized environment:

• One EMC VNX providing thin LUNs to a VMware ESX v4.0 host
• Five VMs running critical OLTP systems supported by one or more databases.
The customer previously experienced some out-of-space conditions due to VMDK
oversubscription. 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 has an ESX 5.0 environment attached to an EMC VNX with VAAI enabled. They
would like to Storage vMotion a guest host to another datastore. How does enabling VAAI on the
VNX benefit Storage VMotion?

A customer configures replication between two Data Movers for their VDM environment. The
primary Data Mover has one 1 Gb copper ethernet port and the destination Data Mover has one
10 Gb optical network port. The customer reports replication is not performing as expected and

The SQL database and transaction logs have been physically isolated on separate RAID groups.
What other actions can be taken to optimize SQL performance?

A customer recently added several new applications to an EMC VNX. Some of the new
applications are experiencing very long response times. The customer suspects a high TCP
retransmission rate is causing the long response times. How could the customer determine the
TCP retransmission rate?

A customer uses MirrorView/S to replicate their production data from Site A to Site C. The
production Oracle server is located at Site A and has access to LUNs 101 and 102. LUNs 101

and 102 are placed in a consistency group. Site A experiences a disaster and production moves
to Site C. What configuration change is needed to provide the Oracle server access to Site C’s
LUNs 101 and 102?

A customer wants to test the workload response of a newly-implemented EMC VNX for File that
will support a Windows client environment. The customer confirms the application workload will
be 80% random writes, of 8 KB or less in size, with bursty patterns of write I/O. Which tool could
be used to simulate this workload for testing purposes?

A customer plans to use SAN Copy to make consistent copies of their Windows 2003 and 2008
production environment at their remote site. Before starting the SAN Copy session, what action
