A customer has an EMC Data Domain integrated into their Symantec NetBackup domain as an
OST device at their production site. They are installing a new NetBackup media server and a
second Data Domain at their disaster recovery (DR) site to protect their client backup images.
How should replication be configured to allow NetBackup to recover client backup data from the
DR site in the event the Data Domain at the production site goes offline?

A customer is integrating an EMC Data Domain into their Symantec NetBackup environment as an
OST device. DD Boost has been configured on the Data Domain. After a few weeks of running
backups, the customer notices the performance is lower than expected.
On the Data Domain, which configuration option should be enabled to offload part of the
deduplication process to the NetBackup media server to improve backup performance?

A customer is implementing an EMC Data Domain system integrating Symantec NetBackup using
CIFS. Which device type should be configured on the backup server to use the Data Domain
system?

You are tasked with installing a new EMC Data Domain system in an existing NetWorker
environment. The customer requirements state that they need the ability to perform multiple
concurrent clone operations from the same device.
Which device type(s) supports the customer’s requirements?

You are tasked with integrating two new EMC Data Domain systems into an existing EMC
NetWorker environment. Due to customer requirements, a VTL will be created on each Data
Domain and drives will be presented to each NetWorker storage node.

Which best practice should be provided to the customer for this configuration?

When implementing NFS with an EMC Data Domain system, why should hard mounts be used?

A customer has EMC Data Domain system installed in their data center for two weeks. The
environment consists of the following.
1. Data Domain is configured as the primary backup device being shared by Avamar, NetBackup,
Oracle RMAN, and SQL Server backup clients
2. Avamar and NetBackup are using DD Boost to backup a total of 500 clients (250 each)
3. Avamar is configured to allow a maximum of 100 concurrent backups
4. NetBackup is configured to allow 150 concurrent backups writing to the Data Domain with the
backup window starting at 8 P.M. nightly
A total of 50 production Oracle servers are using NFS and 50 production SQL servers are using
CIFS, each performing full backups nightly between 11 P.M. and 5 A.M. The archive and
transaction logs backs up every 15 minutes. The retention for all client backups is 30 days.

The backup administrators notice that between 8 P.M. and 11 P.M. every night, the Data Domain
CPU is at 100% utilization. What is a potential reason for the high CPU utilization?

NetBackup has been configured to use an EMC Data Domain appliance as a VTL for the primary
target storage unit. Which multiplexing setting should be configured within the NetBackup storage
unit to achieve optimal deduplication performance on the Data Domain?

A customer notices an improved deduplication rate and write time into their EMC Data Domain
system while multiplexing is turned off. What is the reason?

When using VTL on an EMC Data Domain system, why should persistent binding be enabled on
the host?
