Question 6 Single choice

An EMC NetWorker client is backed up as a guest in a virtual environment. This backup activity indirectly impacts other virtual machines (VMs) on the same ESX server that uses shared resources.

What will reduce this impact?

  1. A

    Define backup policies to limit concurrent jobs on the ESX server

  2. B

    Reduce the frequency of incremental backups

  3. C
