Two new EMC VNX were implemented at a customer’s primary and backup sites. Each VNX has
a single active Data Mover. Multiple VDMs are configured on both VNX, each with a CIFS file
system. The default mapping solution was implemented in a primary-secondary configuration.
The customer completes a security audit and then observes new user authentication fails on the
secondary site. Which TCP/UDP port is being blocked by the firewall?

A customer plans to implement and replicate CIFS on two new EMC VNX. The customer’s
existing environment recently suffered a long outage due to a computer virus. The customer
wants to use CAVA in their new CIFS environment on VNX. Which configuration will satisfy this
requirement?

A customer plans to virtualize their SQL databases on an EMC VNX. They are most concerned
about database performance. How should they design the SQL layout?

An Exchange 2010 environment with 60% reads and 40% writes will be configured on an EMC
VNX using RAID 1/0 15K SAS drives. The total I/O per second required is 3,000. Accounting for
additional overhead for spikes, what is the number of spindles required?

A customer has an existing DR solution using SRDF between Symmetrix at their source and
backup sites. TimeFinder Clones are also used at the backup site. A new VNX is installed at the
backup site. The customer tries to use Incremental SAN Copy to copy data updates from the
TimeFinder Clone to live web server LUNs on the VNX. The customer reports they are not able to
configure the SAN Copy session. Why does the customer need to rework this solution?

A customer wants to reduce the performance impact incremental SAN Copy (ISC) has on their
source LUN. They plan to use a clone between the current source and destination LUNs, and
then use the fractured clone as the new ISC source LUN. The source LUN performs two hundred
4 KB random I/O per second, with a 1:1 read/write ratio.
The source LUN is 768 GB in size, and the clone will be fractured for five minutes.
How much data will be copied to the destination LUN?

A vSphere ESXi 5.0 server is connected to a VNX LUN with several virtual machines on VMFS
datastores. An administrator wants to take a snapshot of one of the virtual machines on the LUN.
Which method can be used?

An implementation engineer installs a DR solution to protect ten CIFS shares at site A. VNX
Replicator will be used to replicate the shares from Site A to Site B.
How many VDMs should be contained in this DR solution for maximum portability?

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 VDMs and
several quota-enabled file systems shared and available to clients via CIFS.
Which solution do you recommend to the customer?

A customer creates an incremental SAN Copy (ISC) session for a 200 GB LUN on an EMC VNX.
The session fails to start, and the customer notes the RLP (reserved LUN pool) contains 300 MB
of storage. What action must be taken to get the session started?
