  B. Replication data is sent directly to the second Data Domain system at the same time the backup is occurring
  C. Cloned backup data can be directly recovered from the second Data Domain system
  D. Backup jobs can start without depending on the server configuration
  A. Backup data is sent directly to the Data Domain system

• Question 3:

  On an EMC Data Domain system, when does the "throttle" setting reduce resource allocation to the file system cleaning process?

  A. When other operations run during file system cleaning
  B. Whenever file system cleaning runs
  C. Whenever any non-cleaning operation runs
  D. Only when replication runs during file system cleaning
  A. When other operations run during file system cleaning

• Question 4:

  What is the name of the dedicated IPMI management Ethernet port on an EMC Data Domain system?

  B. bmc-eth01
  C. bmc-eth02
  D. bmc-eth0a
  A. bmc0a

• Question 5:

  An EMC Data Domain customer has setup a DD VTL for their backup software. They created slots, drives, and tapes. The backup software shows the tape drives and the robot, but not the tapes. Which step was missed on the Data Domain system?
