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

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?

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?

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?

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

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?

A customer is using Data Protection Advisor (DPA) to monitor their backup environment.
What is a benefit of using remote Collectors?

A customer is piloting a Data Domain appliance and notices that performance in the writing of
backups is not optimal. Based on the System Show Performance metrics represented in the
exhibit, which operation will provide the most improved the most improved performance?

A customer has a Data Domain appliance that has reached 90% of maximum capacity. The
customer does not want to purchase any additional storage.
What will increase the average available capacity of the Data Domain appliance?
