  Correct Answer: A

• Question 130:

  An existing EMC Data Domain customer is evaluating new backup software and hardware for their environment. Their current environment consists of a single data center along with several remote sites.

  The customer is interested in consolidating all backup hardware into their primary data center while still being able to do remote backups. In addition, they want the ability to perform backups directly to tape for certain applications in order to send the tapes offsite for long-term retention.

  The customer plans to keep their current Data Domain system as part of any new configuration. However, they want to look at options to optimize performance without adding additional infrastructure.

  The final requirement is that the entire solution be managed from a single unified interface in order to configure and track backup jobs. Which EMC solutions can address these requirements?

  A. NetWorker with DD Boost and an integrated Avamar system

  B. NetWorker with DD Boost along with remote storage nodes

  C. Avamar with an integrated Data Domain system

  D. NetWorker with DD VTL and an integrated Avamar system

  Correct Answer: A
