NS0-163: NetApp Certified Data Administrator, ONTAPDemo

Question

Which two actions should an administrator perform to create a two-node ONTAP Select cluster that extends across two data centers and provides automated switchover with no data loss?

Choose two

A Use ONTAP Mediator service to make sure that a quorum exists for the two nodes
B Make sure that the ONTAP Select Deploy VM resides at a third location other than the two data centers
C Use ONTAP Select Deploy to install the nodes on the VMware environment
D Set up a SnapMirror Synchronous relationship in StrictSync mode to prevent any data loss in case of a failover

Explanation

A stretched two-node ONTAP Select HA configuration relies on the mediator service hosted by the ONTAP Select Deploy VM to establish quorum and manage failures. Hosting that Deploy VM at a third location preserves an independent quorum participant if either data center fails. Data aggregates within the HA pair are synchronously mirrored, providing failover without data loss without configuring a separate SnapMirror Synchronous StrictSync relationship.
