• Question 12:

  A customer is implementing an EMC Data Domain system in their EMC NetWorker environment as illustrated in the exhibit.

• Question 13:

  An organization currently writes backups to an EMC Data Domain system and then creates encrypted copies of their backups on tapes. These tapes are then shipped to a third-party offsite vault.

  They are now planning to deploy a second Data Domain system in a hosted disaster recovery site as a replication target. This will replace the use of the offsite tapes. The two sites are connected through an encrypted WAN link.

  Where should encryption be applied on the Data Domain systems to ensure a similar level of data security as their current process?

  A. Enable Encryption of Data at Rest at the disaster recovery site
  B. Use encryption of data in flight to the hosted disaster recovery site
  C. Enable Encryption of Data at Rest at the source site
  D. WAN link between the sites is already encrypted
  A. Enable Encryption of Data at Rest at the disaster recovery site

• Question 14:

• Question 15:

  What is indicated by a flashing green LED on an EMC Data Domain Expansion Shelf SAS Controller?

  A. Connection in process
  B. Disk in use
  C. Connection established
  D. Connection problem

  Which additional step should be performed to maintain connectivity?

  A. Create a zone between the media server and the Data Domain system
  B. Join the NIS domain
  C. Modify the fstab file
  D. Configure the AFTD device
  C. Modify the fstab file

  C. Amount of data written to disk over 1 minute
  D. Amount of data written to NVRAM over 1 minute
  B. Amount of data written to the network over 1 minute

• Question 18:

  A. Multiplexed streams negatively impact the deduplication process
  B. Data rates increase on the backup server with multiplexing
  C. Data flow is reduced with multiplexing
  D. Multiplexed streams increase backup server disk usage
  A. Multiplexed streams negatively impact the deduplication process

• Question 19:

  A customer is writing critical data to the pre-configured, default NFS export on an EMC Data Domain system for replication to a remote site. Which directory on the local Data Domain system should be reviewed to verify the data is successfully being written?

  C. /data/col1
  D. /data/col1/repl
  A. /data/col1/backup
