They shutdown their production cluster for a scheduled DR test, failed over to the DR cluster, and continue their DR testing. Assume both clusters have identical shares, exports, and user authentication and that the client applications have been stopped and the DNS re-pointed. What is the correct method to continue production operations?

A.    Revert the SyncIQ Policy.
B.    Initiate Manual Failback of the SyncIQ Policy.
C.    Initiate Automated Failback of the SyncIQ Policy.
D.    No change to the SyncIQ Policy.

A customer has two data centers (Site A and Site B) and in each data center there is an Isilon cluster. They are replicating data between the sites using SyncIQ. You have been reviewing their disaster recovery plan and found the following:

What is the most likely reason the failback policy does not replicate data to the primary cluster?

A.    Clusters are not sharing an Infiniband switch.
B.    Secondary cluster has modified files on it.
C.    Original policy was for synchronization.
