  What will occur when the NDMP backups start using default settings?

  A. One NAS device will start its backup with four streams; the other will queue.
  B. Both backups will start, each with two active streams.
  C. One NAS device will start its backup with one stream; the other will queue.
  D. Both backups will start, each with one stream.
  A. One NAS device will start its backup with four streams; the other will queue.

  C. Alternate using Level 1 differential jobs and Level 1 cumulative jobs
  D. Change the Level 1 differential jobs to Level 1 differential jobs
  A. Add a full level backup half-way through the week

• Question 116:

  A Dell EMC Avamar 7.4.1 administrator is testing the file level restore feature from VMware image backups. They restore a large number of files to VM1, then restore the same files to VM2. Both restores succeed, but the restore for VM2 is much slower.
