What TCP ports should they ask the network team to open?
A customer wants to replicate a CIFS environment from a legacy EMC Celerra to a new EMC
VNX. Users are able to access CIFS shares from both arrays. The CIFS shares are on different
networks and replication is not running. The customer wants to make sure there will be no
network restrictions preventing replication between the data movers on two different networks.

What is the reason for this behavior?
A customer recently upgraded from vSphere v4.x to vSphere v5.0 to benefit from new VMFS-5
features for their existing ‘DataStore1’ and ‘DataStore2’ datastores on an EMC VNX. A second
identically configured VNX was implemented and the customer created two additional datastores
on the new VNX.
After monitoring the environment, the customer notices the VMs on ‘DataStore1’ and ‘DataStore2’
are not using the same sub-block structure as the two new datastores.

What could have caused this issue?
A storage administrator reports they are unable configure SAN Copy connections between two
VNX. The required cabling is in place and zoning is correct, but the SP connections still do not
appear in Unisphere Manager. What could have caused this issue?
What is the data distribution after the data is written?
A Pool used for FAST VP has the following configuration:
Flash drives: 1,000 GB, with 1,000 GB free
SAS drives: 5,000 GB, with 2,500 GB free
NL-SAS drives: 20,000 GB, with 11,500 GB free
The tiering policy is set to Auto. An additional 600 GB of new data is written to the Pool.

What recommendation would you give the customer concerning the CIFS DR solution?
You are planning a CIFS DR solution for two existing EMC VNX. Each VNX has dual Control
Stations. Each VNX is also configured for a RecoverPoint protection solution on other VNX LUNs
that are non-file related. What recommendation would you give the customer concerning the CIFS
DR solution?
Which ESXi 5.0 feature would satisfy this requirement?
A customer recently purchased an EMC VNX to be connected to four ESXi 5.0 hosts via FC. Five
of the associated VMs (virtual machines) are running SQL Server 2008 R2. To avoid contention,
the customer wants the VM’s database and log drives on separate datastores.
Which ESXi 5.0 feature would satisfy this requirement?
What is the most likely reason?
An administrator is attempting to vMotion a VM from one vSphere ESXi 5.0 host to another. The
ESXi servers are connected to three VNX arrays on the fabric. The vMotion fails. What is the
most likely reason?
What do you advise?
A customer requires an asynchronous DR solution for an NFS-only client environment. The
customer wants the solution to be simple to implement. It was recommended they create a single
NIS domain, and use several NIS servers to provide centralized authentication to the NFS clients
at both the source and destination sites. The customer asks you whether they should consider
using VDMs in this environment. What do you advise?
What recommendation would you make to help alleviate these hot spots?
A customer has an Oracle ASM database on an EMC VNX with FAST Suite enabled. They
observe intermittent performance degradation due to momentary data hot spots caused by bursty
transaction rates. What recommendation would you make to help alleviate these hot spots?
Which solution do you recommend to the customer?
A customer has a Windows-only environment connected to an EMC VNX for File at their main
campus site. The customer plans to install a new EMC VNX at a remote branch office site. The
new VNX will be used to implement a DR solution for their main campus VNX using several
deduplicated file systems shared and available to clients via CIFS.
