You have a large number of virtual machines that need access to a storage repository.
Which answer describes the factors you use to determine your storage repository strategy?

  1. Oracle VM 3.x has multiple identical storage repositories. Additional identical repositories can be added as needed. A best practice is to select a medium size for the repository based on your usage.
  2. The way to grow an Oracle VM 3.x storage repository is to add additional space to the rootrepository as needed. A best practice is to only configure additional space when determined it is needed.
  3. Oracle VM 3.x has a single fixed storage repository. A best practice is to configure the repository with 30%-40% headroom forgrowth.
  4. The way to grow an Oracle VM 3.x storage repository is to add sub-repositories beneath the root repository. A best practice is to provision one or more larger repositories to avoid the management overhead of numerous sub-repositories.

Answer(s): A

Explanation:

You can use the split technology to split your partitions as a 2 GB space and can define the max size and when needed Oracle VM can automatically add the more storage there and also you can modify the max size of the storage repository.
