• Question 15:

  An administrator has retained snapshots for a single MTree and is trying to create a new one. An error message is received. What is the reason for the failure?

  A. The maximum number of snapshots has been exceeded
  B. The DDOS needs to be upgraded
  C. The user does not have the permission to retain more snapshots
  D. There are not enough snapshot licenses
  A. The maximum number of snapshots has been exceeded

  ---

  Explanation: The maximum number of snapshots allowed per MTree is 750. Warnings are sent when the number of snapshots per MTree reaches 90% of the maximum allowed number (from 675 to 749 snapshots), and an alert is generated

  when the maximum number is reached. To clear the warning, expire snapshots and then run the file system cleaning operation.

  Note: To identify an MTree that is nearing the maximum number of snapshots, check the Snapshots panel of the MTree page regarding viewing MTree snapshot information.

• Question 16:

  What is a main advantage of using DD Boost instead of CIFS or NFS for a backup?

  A. No requirement for an IP network to back up data
  B. DD Boost does not require administration credentials
  C. DD Boost uses integrated network acceleration
  D. Deduplication is distributed between the backup server and client
  D. Deduplication is distributed between the backup server and client

  ---

  Explanation: Dell EMC Data Domain Boost software distributes parts of the deduplication process to the backup server(s) or application client(s), leaving the Data Domain system, powered by Intel® Xeon® processors, to focus its energy on determining what is unique and writing the new data to disk. With DD Boost, only the unique data has to travel from the backup server or client to the Data Domain system. DD Boost also gives the backup application control over replication
