Exam E20-555: Isilon Solutions and Design Specialist Exam for Technology Architects (update January 28th, 2014)

What is the most likely reason for the pausing of some of the SyncIQ jobs?

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.
What is the most likely reason for the pausing of some of the SyncIQ jobs?

What is the Recovery Point Objective in this plan?

A customer has two data centers (Site A and Site B). There is an Isilon cluster in each data center
and they use SyncIQ to replicate data between the two data centers.
You have been reviewing their disaster recovery plan and found the following:

—-The policies specify that SyncIQ runs a replication job every 2 hours and that the job finishes
within 1 hour.
Three additional hours will be needed to get servers and the network redirected to work from
Site

What is the best way to stop the failover operation and continue using the primary cluster?

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?

What is the reason why the target cluster did not automatically allow writes of the data?

An Isilon customer created a scheduled SyncIQ policy to replicate data from an Enterprise-mode
SmartLock directory. The source cluster is now unusable and the target cluster does not
automatically allow writes to the data in the replicated SmartLock directory.
What is the reason why the target cluster did not automatically allow writes of the data?

Which SyncIQ Policy method should be used to continue production operations?

An Isilon customer has two 5-node clusters; one for production and one for disaster recovery (DR).
The customer’s workflows are replicated to the DR cluster through SyncIQ on individual

schedules. They shut down 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. Additionally,
assume the client applications have been stopped and the DNS re-pointed. Which SyncIQ Policy
method should be used to continue production operations?

What is the easiest SyncIQ Policy method to continue operations on production?

An Isilon customer has two 5-node clusters; one for production and one for disaster recovery (DR).
The customer’s workflows are replicated to the DR cluster through SyncIQ on individual
schedules. They have shut down their production cluster for scheduled maintenance, failed over to
the DR cluster, and are currently operating from the DR site.
Assume both clusters have identical shares, exports, user authentication. In addition, assume the
client applications have been stopped and the DNS re-pointed. What is the easiest SyncIQ Policy
method to continue operations on production?
