Exam E20-559: Isilon Solutions Specialist Exam for Storage Administrators

Which step should be taken to troubleshoot this issue?

An organization has two different Isilon clusters: Six-node cluster in London, England
Eight-node cluster in Paris, France They are using SyncIQ to replicate between the clusters.
Each site has access zones configured and SmartConnect Advanced is licensed. The
organization is actively engaged in a failover from Paris to London. During testing, they
realize that users from the Sales department in Paris are receiving authentication errors
from the London cluster. Which step should be taken to troubleshoot this issue?

What is the most likely cause for this error?

An Isilon storage administrator has created a 500 GB quota on a new directory called
‘/ifs/homedirs’. The administrator then begins migrating files from a Linux server through
NFS to the new directory. The migration tool returns a “Disk quota exceeded” error and fails
to complete after approximately 400 GB of files are copied to the Isilon cluster. However,
the cluster is reporting 10 TB of unused capacity. What is the most likely cause for this
error?

what will mitigate re-transmitting the entire dataset over the WAN to the target cluster in the new location?

A company has two Isilon clusters located in San Francisco, California. One cluster is the
source and the other is the target. For efficiency, the dataset is being replicated between the
two clusters within the same data center. The target cluster will be moved to the New York
area as part of a disaster recovery solution once the initial full copy is complete. Once the
cluster has been moved to New York, what will mitigate re-transmitting the entire dataset
over the WAN to the target cluster in the new location?
