A customer is piloting a Data Domain system. Based on the Data Domain statistics represented in
the exhibit, which type of date is being backed up?

An existing EMC customer notices that garbage collection is not running in Avamar because the
capacity limit has reached. At which capacity limit does garbage collection stop running?

You are designing an EMC NetWorker deduplication solution for a customer. When performing a
restore of a backup containing multiple save sets from a deduplication node.
What is the maximum number of save sets that can be recovered concurrently?

While running a three-month pilot using a Data Domain appliance, a customer produces the space
utilization graph shown in the exhibit.
What does the “saw tooth” line for the compression ratio represent?

A customer is considering the use of offsite physical tape vaulting rotation for compliance
purposes. What is a key concern to discuss with the customer?

A customer plans to integrate an EMC Disk Library (EDL) with NetWorker. The customer has
purchased an Embedded Storage Node License to clone virtual taped from the EDL to a physical
tape library.
What should be included in the design document design to ensure the Embedded Storage Node
reads the data from virtual tape during a clone operation?

You are designing a backup solution for an EMC NetWorker customer. Based on EMC best
practices, how many CPU cycles are needed by the storage node when backing up clients over
the network to local tape drives at a rate of 100 MB/s?

A customer has recently added a Celerra to their environment and has asked you to assess their
current data protection methodology. They currently have an EMC NetWorker environment using
an EMC Disk Library (EDL) as the primary backup location before they move the virtual tapes to
physical tapes.
How over, the rate of change of the data on the Celerra is too high for their RPO using the EDL for
single file recovery if their backups are performed only at the end of the business day. What would
you incorporate to lessen the impact of their once-a-day backup schedule on the Celerra data with
minimal impact to their backup administration processes?

An EMC NetWorker customer is considering using the deduplication feature with Avamar. What is
a requirement when performing backups to a deduplication node?

An EMC Avamar customer has a heavily utilized ESX system CPU utilization is a concern. Each
guest system, all of which are Linux must be backed up with file granularity. The customer has
both Avamar and NetWorker available and is looking to EMC for guidance
What is considered the most suitable approach to meet these requirements?
