• Question 93:

  An EMC NetWorker customer's environment consists of four VMware ESXi hosts with 20 virtual machines on each ESXi host.

  B. Distributed Segment Processing on the storage node

  C. DD Boost on the storage node

  D. DD Boost license on the NetWorker server

  Correct Answer: A

  C. Scientific and big data

  D. Monthly full and daily incremental backups

  Correct Answer: A

• Question 96:

  You are designing a backup solution for an EMC NetWorker customer. Given a conservative estimate, how many CPU cycles are needed by the storage node when backing up clients over the network to local tape drives at a rate of 100 MB/s?
