QUESTION 81
A customer created eight SyncIQ policies on a 6-node Isilon cluster. The policies all start at midnight. The customer is experiencing issues where several jobs are paused while others continue to run. This is delaying the overall replication of data.

QUESTION 86
An Isilon customer has set up a replication policy between a primary cluster and a secondary cluster. After the initial synchronization of the clusters, the primary cluster starts to display some issues. The customer initiates a failover operation between the two clusters. During the failover, the primary cluster becomes fully operational again. The customer wants to stop the failover operation between the two clusters. What is the best way to stop the failover operation and continue using the primary cluster?

A. SyncIQ Automated failover is not supported for SmartLock directories; however, manual failover is allowed.
B. Automated failover and manual failover are not allowed on SmartLock directories on the target cluster.
C. A SyncIQ job was running while the source cluster became unusable, thereby removing all data on the target directory.
