Which features will have a negative impact on the performance of an EMC Data Domain

system?

A new EMC Avamar customer is concerned with data security since all backup data is
stored on disk. To minimize the customer’s concerns, you have recommended the
encryption-at-rest feature. What is a consideration when using this feature?

A customer has a new EMC Avamar server with four 3.9 TB data nodes. This server is

backing up two Avamar clients. The first client has 8 GB of RAM and two file systems. The
first file system has 3 million files consuming .75 TB. The second file system contains 5
million files consuming 1 TB of space. The second client has 10 GB of RAM and one file
system containing 4 million files is consuming 1.2 TB of space. Both clients will belong to
the same backup group. How long will the steady state backup group be expected to run?

A customer’s backup solution is reaching the end of warranty. The customer has installed
an Avamar solution for their file server and ESX servers. They want to move all the backups
to this environment. Deduplication for the databases is critical and they want to maintain the
EMC Data Domain VTL. In order to integrate Data Domain into the Avamar installation,
which hardware and software options need to be installed on the Data Domain system?

Your customer has been a long time Avamar Virtual Environment (AVE) customer. They
have older AVE installations along with newer installations. They notice that older
configurations are not receiving the same performance as the newer configurations. The
customer points out that both configurations have fairly high I/O requirements but use
different disk pools. They understand performance is affected by RAID levels and would like
your recommendation. Based on best practice, which RAID level is recommended for virtual
machines with high disk usage?

A customer currently has a multi-node EMC Avamar solution with eight active storage
nodes. They are currently at 85% GSAN capacity and receiving capacity warning
messages. The customer would like to purchase additional capacity for the system. What is
a best practice for adding capacity?

A customer has difficulty keeping up with their restore requests on their existing backup
solution. Currently each restore requires the backup team to engage and manually process
each restore request. The customer wants the clients to be able to restore and browse their
own data using only their account credentials. Which EMC solution meets the customer’s
requirements?

A customer has an Avamar system that has reached 100% of maximum capacity. The
environment consists of a 16 active data node system. What can be done to decrease the
utilized capacity?

You have suggested to a customer that a Data Deduplication Assessment A (DDA:A) would
help them evaluate deduplication in their environment. What would you recommend after
the completion of the DDA:A scan?

An EMC Avamar customer is unable to successfully complete a nightly backup of a large file
server within their defined backup window. The server is a single quad core system with 2
GBs of RAM. The file system data is being stored on a RAID 5 SAN disk. Currently, the
server has 7 million files totaling 1 TB of data spread across three volumes. The Avamar
agent was installed and configured using the default settings. What should be
recommended to increase the performance of the nightly backup?
