An Isilon customer has two 5-node clusters, one for production and one for disaster recovery (DR). The customer's workflow is a SmartLock workflow and is replicated to the DR cluster through SyncIQ on an individual schedule. The customer needs to shutdown their production cluster for scheduled maintenance.
Assume both clusters have identical shares, exports, user authentication, and that the client applications have been stopped and the DNS re-pointed. What is the correct method to start operations on the DR cluster?

1. A. Initiate Manual Failover of the SyncIQ Policy
2. B. Initiate Automated Failover of the SyncIQ Policy
3. C. No change to the SyncIQ Policy
4. D. Revert the SyncIQ Policy

An Isilon customer is experiencing less than expected performance and poor space utilization with their cluster. They are using the X400 nodes with an N+2d:1n protection policy to host web server log data. Upon further analysis, the customer discovers that the web servers write log files 64KiB in size. The log files are then accessed by an analytics application for reporting purposes. What should be done to increase the write performance of the cluster?

1. A. Change the protection scheme to a mirroring policy
2. B. Add S-Series storage nodes to the cluster
3. C. Add A-Series Performance Accelerator nodes to the cluster
4. D. Change the SSD strategy on the cluster

Correct Answer: C

How does Isilon SnapshotIQ use storage for snapshots?

1. A. Through Changed Block Tracking and only changed data blocks are saved
2. B. Works on the file level and saves the entire file no matter what has changed
3. C. Works with 4 KiB blocks and will always use that amount of storage, no matter what has changed
4. D. Through Changed Block Tracking and always uses a 4 KiB block, even if the data changed is less than that amount

Correct Answer: A

A customer configures a file pool policy to write data to tier 2 on the Isilon cluster. This is in addition to the 30 policies already created. Later in the week they check the file placement and see that it has not been written to the correct tire. What could be the problem?

1. A. Number of allowable policies has been exceeded so the new policy will not run.
2. B. File matches a policy for a different tier that is listed higher in the file pool policy list.
3. C. SmartPools policy job has not yet run so the file was written using the default policy.
4. D. File matches a policy for a different tier that is listed lower in the file pool policy list

Correct Answer: B
