QuestionQ12

ONTAP replication technologies

You must protect all data in a storage VM (SVM) that serves NAS data, subject to these requirements:

  • All volumes in the SVM must be protected.
  • The source and destination SVMs reside on the same subnet.
  • The source SVM hosts volumes for multiple applications.
  • DR testing for a single application is required without disrupting the other applications.

Which data-protection solution meets these requirements?

  • A Use SyncMirror.
  • B Use SVM DR with identity-preserve set to true.
  • C Use SM-BC with the ONTAP Mediator.
  • D Use SVM DR with identity-preserve set to false.
Explanation

ONTAP SVM DR with identity-preserve set to false replicates the SVM’s volumes while excluding its network identity, allowing the destination SVM to use independently configured network access when the source and destination are on the same subnet. This avoids identity and network conflicts during DR testing while protecting the SVM’s volumes. NetApp documents that identity-preserve false replicates the volumes and selected SVM security, protocol, and name-service configuration, whereas identity-preserve true replicates the entire SVM configuration.
