A customer is implementing s Data Domain system with two expansion shelves. They require that
access to the data can be reached even when a single path fails. The customer does not want the
HBA card to be the single point of failure.

The EMC account team has been asked to redesign a NetWorker backup solution. The existing
backup environment consists of one NetWorker server and one storage node to back up
approximately 80 clients. Over time, the amount of data increased, resulting in daily backups
taking more than 24 hours to complete.
Analysis has determined that the tape infrastructure and the network are not the bottleneck. What
would you recommend to improve the backup performance with minimal costs?

Which critical network elements are assessed by the Network Assessment Tool?

An EMC NetWorker customer performs all backups to physical. The customer backs up file
systems, application servers, VMware guests multiple 10 TB database, and a large 20 TB NetApp
filer. They have a primary and disaster recovery data center with an OC-12 circuit between the two
sites.
The customer’s physical tape libraries are approaching end of support life and they are looking to
replace them with deduplication technology. In addition, they want to improve NDMP backup times
for their 20 TB NetApp filer.
Which recommendation will address the customer’s requirements?

A customer has approached you to advise them on how their backup environment will integrate
into their new iSCSI application server deployment. Which network characteristic would have the
greatest impact on their backup environment?

A customer has a database server with 300 GB of Oracle database data. Using the default hash

cache setting, what is the total amount of physical RAM required on the client?

What is a key consideration when assessing a nested mount file system and an NDMP Volume
Based Backup (VBB) backup strategy?

An EMC NetWorker customer is considering using an EMC Disk Library as a target as shown in
the exhibit. Two storage nodes need to access the same pool of virtual tapes. In addition, the
customer wants to load balance the usage of virtual tape drives across the available connections.

Based on EMC best practices, which satisfies these requirements?

A customer has twofiles that have been locked and backed up to Data Domain appliance with the
following parameters:
·File1=atime=20 years
·File1=atime=5 years
The Data Domain global retention periods are configured as follows:
·Min=2 years
·Max=10 years
The administrator changes the Data Domain maximum retention period to 4 years. After how
many years can File 2 be deleted?

An EMC NetWorker customer has an Oracle database client. To achieve acceptable backup
performance, they have configured the backup to use four RMAN channels.
The customer wants to benefit from adding Avamar deduplication for this backup. What is a
consideration before proposing this design change?
