Your customer has observed a degradation in response time while browsing for media files within the Production Media folder of the Isilon cluster. That directory now contains over five million files. It was confirmed that there are no network or edit station related causes.
What changes to the Isilon cluster will best accelerate the browsing performance?
- A . Add Solid State Drives (SSDs) to the nodes
- B . Add A-Series Performance Accelerator nodes
- C . Upgrade node access to 10 Gbps
- D . Upgrade RAM on the nodes
While validating the value (VTV) with a large educational customer, they have decided they would like to add a Disaster Recovery (DR) site to their existing Isilon environment. The existing cluster contains six X-Series nodes. They plan to have all workflows replicated to the DR site and both clusters will have identical shares, exports, and user authentication. The customer would like to test DR failover every six months by running their production environment from the DR site.
What would you recommend for the DR solution?
- A . SyncIQ and identical cluster at the DR site
- B . SmartConnect and NL-Series nodes at the primary site
- C . SyncIQ and NL-Series nodes at the DR site
- D . Equal number of S-Series nodes at the primary site
A hospital is considering using Isilon to store their archived medical images and Genomic Sequencing data. They currently have 56 TB of PACS images and 24 TB of genomic data, and expect to double their capacity requirements this year. They will replicate to a DR cluster, and plan to use N+2 protection. The production workload needs to be run at either site.
Which minimum cluster configuration, at each site, including software, would meet this customer’s environment?
- A . Five X400 (2 TB drives) nodes with SyncIQ.
- B . Four NL400 (3 TB drives) nodes with SyncIQ.
- C . Seven X200 (3 TB drives) nodes with SyncIQ and SnapshotIQ
- D . Five X400 (2 TB drives) nodes with SnapshotIQ.
A hospital is considering using Isilon to store their long-term archive data for their GE PACS application. They currently have two million 17 MB studies. They expect capacity requirements to be 50% compounded growth per year. They plan to use N+2:1 protection, and would like this sized for three years of growth.
Which minimum cluster configuration would meet this customer’s environment?
- A . Five NL400 (1 TB drive) nodes
- B . Four NL400 (2 TB drive) nodes
- C . Five X200 (3 TB drive) nodes
- D . Three X400 (3 TB drive) nodes

Which tool would allow the customer to forecast capacity requirements?
- A . InsightIQ
- B . Isilon SNMP MIB
- C . SyncIQ
- D . SmartPools
Which Isilon feature provides the ability to build a cluster using different node types and tiers to meet a customer’s business objectives?
- A . SmartPools
- B . SmartQuota
- C . SmartConnect
- D . SnapshotIQ
At which level can retention periods be applied with Isilon SmartLock?
- A . Directory
- B . Node
- C . File system
- D . Cluster
A customer is trying to get Isilon SyncIQ to run on the two clusters they just purchased.
However, they are experiencing some problems. They have asked you to explain how the SyncIQ licensing works.
What information can be provided to the customer?
- A . SyncIQ license is required on both the source and target clusters
- B . SyncIQ license is required on the source but not on the target cluster
- C . SyncIQ license is required on target but not on the source cluster
- D . SyncIQ license is included in the OneFS license; no additional license is needed
