A customer would like assistance with the design of an EMC Data Domain environment.
Based on best practices, what should the customer know about Data Domain MTrees?

An existing EMC NetWorker customer is planning to integrate EMC Data Domain systems
into their backup infrastructure. They would like to: – Backup their Microsoft Windows client
data using CIFS to a Data Domain system – Take weekly Data Domain system snapshots of
Windows client backup data – Backup their Linux client data using NFS to a Data Domain
system – Take daily Data Domain system snapshots of Linux client backup data Based on
EMC best practice, what should be considered when designing the Data Domain file system
layout?

A customer has an environment that consists of 50 clients, EMC NetWorker, and a Data
Domain system. The customer wants the ability to obtain individual client deduplication
ratios. What must be done to ensure there is no performance loss on the Data Domain
system?

While designing an EMC Data Domain solution for a customer, you want to determine the
amount of storage capacity needed. You have discovered the following information: What is
the burn rate (in GB)?

A customer wants an EMC Avamar solution that provides 8 TB of deduplicated data
protection. In addition, they need to protect a VNX system and export data to tape. They
anticipate data growth of another 6 TB in the next year. Which Avamar components should
be used to architect the solution, in as few nodes as possible, while meeting sizing best
practices?

A customer has 6,000 desktops and laptops with 1 TB of data, an average backup time of
10 minutes each, and 10 TB of database data. The customer wants a solution that

addresses the following requirements: – Deduplication in the shortest backup window with
the fewest components – Least performance impact on the database servers Which Avamar
solution is recommended?

An existing EMC Avamar customer wants to add a new database 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 database of 500 GB?

You are assigned to upgrade an existing EMC NetWorker server. You ask the customer to
run the nsrlic –v servername command and send you the output.

An EMC NetWorker customer is considering implementing deduplication into their existing
environment. Which design consideration has the most positive impact on the deduplication
ratio?

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?
