A customer has been using lz Local Compression when backing up their data to an EMC Data
Domain system.
An audit of their storage content shows that they can effectively use gz compression for their data.
What should be considered before changing the Local Compression type?

A large EMC NetWorker customer is gathering installation requirements for a new NetWorker
installation. Based on best practices, where should the NetWorker indexes be located to provide
the most flexibility?

An EMC NetWorker customer is considering backup options for their VMware environment. The
environment consists of Microsoft Windows file servers an Oracle database server running on

Solaris. What is an advantage of using the VMware image backup operation?

An existing EMC NetWorker customer is evaluating options for upgrades within their backup
solution. The customer is interested in replacing their current tape-based infrastructure with a
backup-to-disk product. The customer currently uses EMC VNX arrays for their SAN storage.
The solution needs the ability to retain certain backups for long periods of time due to compliance
reasons as well as minimize the amount of power and rack space required. In addition, all backups
must go offsite on a daily basis.
Finally, the customer wants the ability to use a new 10 GigE infrastructure they are planning to
deploy within their data center. They want to minimize the amount of disruption to their current
daily procedures in order to avoid re-training existing staff.
Which storage solution can be integrated with NetWorker to satisfy these requirements?

A customer wants to improve the performance of their EMC Data Domain system. After checking
their weekly reports, they notice that on the same day each week, file system performance is
impacted. At first the customer thought the performance issue was caused by full backups that run

on Friday. However, the performance issue is occurring on Tuesday.
What is a possible reason for this behavior?

An EMC NetWorker customer is backing up all clients using EMC Avamar deduplication. They
have a requirement for backup redundancy for disaster recovery.
What is recommended to provide this protection?

A new EMC Avamar customer wants advice on setting up their groups and schedules. They are
migrating from a traditional tape backup solution with a mixed retention policy. Both Microsoft
Windows and Solaris clients will be backed up.
What follows EMC best practices for setting up groups and policies?

An EMC Avamar customer is in the testing phase of their new solution. They have backed up
several clients and are now doing some restore tests. They have found that the restore time is not
consistent. The restore time decreases if more than one attempt at the same restore is performed.
Why is the customer seeing these results?

An existing EMC NetWorker customer has been backing up their VMware environment using
VMDKs to a CIFS-attached EMC Data Domain system. Recently, they have added another 80 TB
to their primary VM storage. While their deduplication rates have exceeded expectations, they are
starting to overrun their backup window.
Which solution compliments their existing infrastructure?

Refer to the Exhibit.

A customer is planning to have a disaster recovery solution for their backup environment. As part
of Phase 1, they want a replica for their EMC Data Domain system. Due to some budget
restrictions, they need to have a low investment solution.
What is the recommended minimum configuration needed for the replica?
