QuestionQ1

ONTAP replication technologies

You must replicate data from site A to two distinct disaster-recovery sites at remote locations B and C. You want destination data to be as current as possible with the source site if an outage occurs.

Which two configurations meet this objective?

Choose two
  • A a cascade deployment consisting of a SnapMirror Synchronous relationship from site A to site B to site C
  • B a fan-out deployment consisting of a SnapMirror Synchronous relationship from site A to site B, and an asynchronous relationship to site C
  • C a fan-out deployment consisting of a SnapMirror Synchronous relationship from site A to sites B and C
  • D a cascade deployment of a SnapMirror Synchronous relationship from site A to site B, and an asynchronous relationship from site B to site C
Explanation

SnapMirror Synchronous supports a fan-out configuration with only one synchronous relationship; every additional relationship originating at the source must be asynchronous. It also supports a cascade in which the primary-to-secondary relationship is synchronous only if the secondary-to-tertiary relationship is asynchronous. Therefore, a synchronous A-to-B plus asynchronous A-to-C fan-out, and a synchronous A-to-B plus asynchronous B-to-C cascade, are supported.
