6. F. Multiple restripe or mark job phases cannot safely and securely run simultaneously without interfering with each other and without risk of data corruption.

Correct Answer: A

A customer has an Isilon cluster that they want to simplify a Hadoop workflow. The workflow analyzes large amounts of log data written to storage using FTP and results are viewed by Microsoft Windows clients?
How can this be achieved?

1. A. FTP, SMB, and HDFS NameNode and DataNode protocol support on the same file system to enable each workflow step to access data from the same location avoiding data migration.
2. B. SyncIQ to migrate the log data between an Isilon cluster and another Hadoop cluster, to retrieve results from the Hadoop cluster, and to store them in an SMB share.
3. C. SmartConnect to direct clients to an external Hadoop NameNode and to SMB shares so data ingest, analytics, and results phases are transparently directed.
4. D. FTP and SMB protocol support to provide log ingest and Windows clients; SmartPools will stub to HDFS helping to reduce the frequency of external data migration.

Correct Answer: A

An Isilon customer wants to more effectively manage their storage and thereby achieve performance improvements. Which tool will help improve workflow performance on their cluster?

1. A. InsightIQ
2. B. Isilon SNMP MIB
3. C. SyncIQ
4. D. SmartPools

Correct Answer: A

A cost-conscious customer is exploring Isilon for their PACS archive. The workflow consists of one hundred cases a day, each including fifty 60MB image files. However, each image will have five-hundred 64kB metadata files associated with it. They currently have six years worth of archived data. They will need to migrate to the new solution and they need to plan for an additional three years of archive capacity.
Which solution would you recommend to fit their capacity needs?

1. A. 24 NL-Series nodes with N+3 protection policy providing 2597 TiB of useable capacity
2. B. 18 NL-Series nodes with N+2:1 protection policy providing 2078 TiB of useable capacity
3. C. 24 X-Series nodes with N+3 protection policy providing 2597 TiB of useable capacity
4. D. 12 NL-Series nodes with N+2 protection policy providing 1300 TiB of useable capacity

Correct Answer: A

A customer's cluster contains three X200 (24 GB RAM, 3 TB drives) nodes, and three X400 (48 GB RAM, 1 TB drives) nodes. All nodes are configured in a single pool. All data is protected at N+2. After upgrading OneFS to 7.0, the Isilon Web interface indicates that files are not fully protected.
What should be done to correct this situation?

1. A. Recreate the original pool using the Isilon Web interface
2. B. Add 24 GB RAM to each of the X200 nodes
3. C. Recreate the original pool using the command line interface
4. D. Add two X200 nodes and two X400 nodes

Correct Answer: C
