You are designing a Data Protection Advisor (DPA) solution for a customer. As a part of the
engagement, you are required to configure the DPA stores. What is the minimum size you
would recommend for configuring the stores?

A customer wants to know why their backup performance to an EMC Avamar multi-node
server has decreased. Initially they were seeing an ingest rate of approximately 5 to 7
GB/hr/node. Recently they estimated that the ingest rate has slowed to around 3 to 5
GB/hr/node. What is a probable cause for the decrease in the average ingest rate?

You are designing a backup solution for an EMC NetWorker customer. Given a
conservative estimate, how many CPU cycles are needed by the storage node when
backing up clients over the network to local tape drives at a rate of 100 MB/s?

A customer’s environment consists of the following: – Linux servers with an Oracle
database. – Microsoft Windows with SQL. – Full weekly backups for Oracle with a one-month
retention period. – Dairy incremental with a two-week retention. – Full weekly backups for
SQL with two retention periods. You collect the information in order to determine the
capacity needed for an EMC Data Domain solution. Which calculation will show the best
trade-off between retention and compression?

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?
