NetApp Certified Implementation Engineer – ONTAP v5 — Question 1

You are asked to replicate data from site A to two separate disaster recovery sites at remote locations B and C. You want the data at the destinations to be as up-to-date as possible with the source site, in case of an outage.
In this scenario, which two configurations satisfy the objective? (Choose two.)

Answer options

• 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

Correct answer: B, D

Explanation

The correct answers B and D allow for timely data replication to the remote sites while maintaining the necessary synchronization. Option B establishes a synchronous link to site B for real-time updates, and an asynchronous link to site C, which is acceptable for less critical data. Option D allows for synchronous updates to site B and utilizes an asynchronous method to propagate changes to site C, providing flexibility in recovery strategies. Options A and C do not meet the requirement for maintaining the most current data at both disaster recovery sites simultaneously.
