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?
SyncIQ Automated failover is not supported for SmartLock directories; however, manual failover is allowed.
Automated failover and manual failover are not allowed on SmartLock directories on the target cluster.
A SyncIQ job was running while the source cluster became unusable, thereby removing all data on the target directory.
SnapshotIQ was not licensed on the target cluster; the snapshot of the directory is not available for use by SyncIQ.

A customer is inquiring about expanding their primary cluster consisting of six S-Series nodes in order to improve performance. They have a second cluster with 11 X-Series nodes. Both clusters leverage 1GbE, but the customer recently installed a 10GbE network that can be utilized. They also have multiple Fibre Channel SAN arrays in their environment. They have a variety of workloads on each cluster and are in the process of determining which workloads belong on which cluster. They have discovered that one of the workloads- a SQL database that resides on the X-Series node cluster - is experiencing timeouts due to latency. The database vendor has suggested limiting latency to 5ms or less to eliminate these timeouts. How do you advise the customer?
Consider migrating data from Isilon to one of their SAN platforms or proposing a new solution to handle the performance requirements of SQL.
Merge the S-Series nodes and X-Series nodes into one cluster, upgrade the 1GbE to 10GbE, and leverage SmartPools to allow for the cluster to determine where data should reside.
Suggest the customer consider leveraging SSDs in the new nodes they purchase and GNA to boost the performance of each cluster.
Recommend they increase the amount of DRAM in the cluster or consider an Accelerator node in order to increase the amount of cache in their cluster.

Your customer has an Isilon 4-node X400 cluster used for home directory use, and has since updated to OneFS 7.0. The HR and Legal departments have been very strict about using only dedicated file servers that are part of a single, isolated, untrusted Active Directory domain. Their filer has been out of maintenance, and fears are being raised that, due to the age, it may fail at some point. What could the IT department do, to allow the HR and Legal groups to provide file share services, with minimal impact to their other application permissions?
Recommend a 2nd cluster for the HR/Legal department
Utilize SmartPools to create two pools to separate the domains
Consolidate onto a single cluster and merge the domains
Use Access Zones for each domain
