  B. Configure Email Home for the EMC Data Domain VTL

  C. Capture baseline performance of client servers

  D. Configure network monitor

  Correct Answer: A

• Question 4:

  You are having a preliminary discussion with a prospective customer. The customer would like to know the deduplication rates that are typically seen when running initial EMC Avamar backups for file system and database data.

  Which information should be provided to the customer?

  A. File system = 20%; database = 80%

  B. File system = 50%; database = 50%

  C. File system = 70%; database = 35%

  D. File system = 80%; database = 20%

  Correct Answer: A

• Question 5:

  An 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.

  Their requirements are:

  Consolidate all backup hardware into their primary data center while still being able to perform remote

  backups. Continue to perform backups directly to tape for certain applications in order to send the tapes

  offsite for long-term retention. Keep their current Data Domain system as part of any new configuration.

  Optimize network performance without adding more hardware infrastructure. Manage the entire solution

  from a single unified interface.

  Which solution addresses these requirements?

  A. NetWorker with Data Domain Boost only

  B. NetWorker with Data Domain Boost and storage nodes at the remote sites

  C. Avamar with an integrated Data Domain system

  D. NetWorker with Data Domain VTL and an integrated Avamar system

  Correct Answer: A

• Question 6:

  An existing EMC NetWorker customer is evaluating options for upgrades within their backup solution. The customer is interested in replacing their current tape- based infrastructure with a backup-to-disk product. The customer currently uses EMC VNX arrays for their SAN storage.

  The solution needs to be able to retain certain backups for long periods of time due to compliance reasons, as well as to minimize the amount of power and rack space required. In addition, all backups must go offsite on a daily basis. Finally, the customer wants to be able to use a new 10 GigE infrastructure they are planning to deploy within their data center. They want to minimize the amount of disruption to their current daily procedures in order to avoid re-training existing staff.

  Which storage solution can be integrated with NetWorker to satisfy these requirements?

  A. Data Domain Boost to Data Domain device with Extended Retention

  B. Avamar and Data Domain with Data Domain I/OS license

  C. Data Domain VTL and Data Domain device with Extended Retention

  D. Data Domain and VNX with Data Domain I/OS license

  Correct Answer: A

• Question 7:

  A company has a large Oracle database and is using NetWorker Module for Databases and Applications for its backup. In this backup environment all the servers are impacted due to the huge volume of backup data.

  Which solution would minimize the impact on the backup environment?

  A. Back up only changed data instead of daily full backup

  B. Include all database objects along with system tables

  C. Use Microsoft VSS to create snapshots

  D. Use Replication Manager along with the NMDA

  Correct Answer: A

• Question 8:

  A customer wants to perform a data center refresh. They want to standardize their backup infrastructure by using EMC NetWorker and Data Domain in an integrated environment.

  The environment consists of: A primary data center with NetWorker and Data Domain 220 remote sites; each remote site consists of 30 clients and one storage node with three devices per storage node. Each remote storage node device will have a target session of 12 and a max target session of 60.

  By default, what is the maximum nsrmmd count per device?

  A. 5

  B. 9

  C. 12

  D. 60

  Correct Answer: B

• Question 9:

  An existing EMC NetWorker customer has been using VMDKs to back up their VMware environment to a CIFS-attached Data Domain system. Recently, they have added 80 TB to their primary VM storage. While their deduplication rates have exceeded expectations, they are starting to exceed their backup window.

  Which solution is recommended to integrate with their existing infrastructure?

  A. Change the NetWorker and Data Domain configuration to use DD Boost

  B. Introduce a VTL configuration to the Data Domain system and transfer data over Fibre Channel.

  C. Switch the NetWorker VMDK configuration to a NetWorker guest client configuration.

  D. Add a NetWorker dedicated storage node into the backup environment.

  Correct Answer: A

• Question 10:

  The Exchange 2010 environment consists of the following: 4 mailbox databases, where each mailbox database is approximately 500 GB in size Each Exchange transaction log is approximately 50 GB in size

  The NetWorker backup server is configured as: Leverage Microsoft VSS Perform incremental backups of the Exchange data once every 4 hours every business day Roll over all the snapshots to a Data Domain system Today (Tuesday), the Exchange DBA adds a new mailbox database (approximately 10 GB in size) to the Exchange server.

  What is the approximate size of the backup set being rolled over by the next NetWorker backup?

  A. 10 GB

  B. 60 GB
