An EMC NetWorker customer is experiencing poor backup performance. Your analysis
determines that significant host resources are used to manage low-level network
handshaking operations during backup. Based on EMC recommendations, what can be
done to alleviate the handshake issue?

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 10 GB of RAM and two file systems. The
first file system has 2 million files consuming .75 TB. The second file system contains 3
million files consuming 1 TB of space. The second client has 8 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 is planning a new database rollout using Oracle and wants to perform online
backups. Initial tests with EMC NetWorker have shown that the backups cannot be
completed within the backup window of six hours. You have analyzed the backup
environment and there are adequate resources to meet this backup window. What is one of

the first things to check in NetWorker or RMAN to increase performance without adding cost
and complexity?

You are redesigning an EMC NetWorker customer’s backup solution. Currently all file
system clients are backing up to an EMC Avamar deduplication node The customer wants
to add another Avamar server and back up some of the larger clients to the new Avamar
deduplication node. What is the impact of this decision?

When sizing an EMC Avamar or Data Domain solution, what are important challenges that
should be taken into consideration?

A customer is considering EMC Avamar for backing up servers in their remote offices.
Currently they are facing WAN capacity issues and the backup of their Microsoft Exchange
server at the primary site is critical. Which type of Avamar solution is suitable for the
customer’s environment?

An EMC Data Domain customer has ordered three expansion shelves to increase the active
tier storage capacity for backup. After successfully installing the new expansion shelves, the
Data Domain GUI is partially showing the new extra capacity. What is the reason for this
issue?

The EMC account team has been asked to design an EMC NetWorker backup solution for a
VMware ESX environment with the following requirements: 1. Online backup of the
Microsoft Exchange server running on a virtual machine 2. File-level backup and recovery
for all virtual machines running Microsoft Windows. Which backup solution addresses both
requirements?

An EMC Data Domain customer is planning to implement a replication solution in order to
have their production environment protected at a remote site. The bandwidth for their SRDF
replica is 40 Mbps which they are planning to share with the Data Domain replica. Based on
the exhibit and given an 8-hour replication window, which information will determine the
bandwidth requirements?

An existing EMC Avamar customer wants to add a new file system client to their Avamar
system. This is a moderately full Avamar single-node server running in steady state. What is
the estimated time to backup this file server of 3 million files?
