You get a call from the customer asking about Active Directory integration for user mapping. They
have used EMC NAS products for over ten years and have extended the schema some years ago.
Now they are trying to migrate to default Windows Services for UNIX (SFU, aka IDMU) for the
UID/GID needs.
Which statement best describes the choices available?

A customer is concerned about UserMapper database and asks you what will happen to the VNX
CIFS users if UserMapper is unavailable.
What do you advise them?

Your customer has recently purchased a VNX for File. Due to the budget limits, they were unable
to purchase enough SAS drives to create all of their required file shares. They would like to use

their NL-SAS drives but are concerned about lower performance.
What EMC solution do you propose?

Your customer is designing a CIFS application with very specific high CIFS I/O requirements.
What is the best recommendation when designing the CIFS storage pool?

You are planning a file-only implementation where the customer will be using AVM. You want to
make the best use of storage pools to preserve the performance of VNX.
Which statement offers the best storage pool guidance for file system creation with AVM?

Your customer is using the front-end iSCSI ports on their VNX. They are experiencing long delays
and reduced bandwidth as they add servers to their environment.
Which option will increase the customer’s overall bandwidth while maintaining EMC best practices
for iSCSI?

Your customer currently has a Block-only VNX. They now want to add file services to replace an
older Windows Server cluster. You are planning to add the file option to the current configuration.
Where in the configuration do the Control LUNs for file reside?

A customer created a user-defined storage pool to physically segregate the file systems of a

business unit. The customer was careful to select LUNs from different RAID Groups for the userdefined pool. After creating a file system from this storage pool with AVM, the customer
discovered that the file system was created on a single LUN instead of multiple LUNs for better
performance.
What do you recommend to make AVM use multiple LUNs when creating a file system from the
user-defined pool?

You are asked to design the backend layout for a large Unified Storage VNX. You find that the
customer intends to use most of the disk space for block-level devices in the SAN.
How should NAS RAID Groups be selected on the array for optimum AVM performance?

A customer has an existing Unified VNX which is used only for block data. They are now looking to
consolidate a few Windows servers onto the VNX. There is empty space on existing pools, which
the customer is planning to use for file storage.
What would you advise the customer?
