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?
