Correct Answer: A

A telecommunications company has a substantial amount of data. This data is being created by network elements within their environment.
The company wants to change the way the network elements Call Detail Records (CDR) are stored and analyzed. The existing infrastructure consolidates all of the CDRs into a table structure, and then ingests them into a large database. Once ingested, a query engine accesses the database and performs analysis on these files. The system is functional; however, since the amount of CDRs generated will increase exponentially over the next year, the company is open to alternatives for storing and analyzing these records.
In evaluating alternatives, the key requirements are to reduce cost, the amount of storage, and the amount of time to analyze the data. The customer would like to use Hadoop to analyze the CDRs.
After you have conducted an assessment of the workflow, you have recommended an Isilon Cluster to work within the Hadoop environment.
Considering the customer's requirements, which is the best node type for the Isilon cluster?

1. A. NL400 with 48GB RAM and no SSDs per node
2. B. X400 with 96GB of RAM and no SSDs per node
3. C. X400 with 24GB RAM and 1.6TB of SSD per node
4. D. X200 with 24GB of RAM and 1.2TB of SSD per node

Correct Answer: B

A customer experiences a system failure on an Isilon storage node.However, the disk drives in the node are not affected.
What is the preferred method for restoring cluster integrity?

1. A. Engage EMC support to perform a Disk Tango process to move drives, journal, and boot volumes to a replacement chassis
2. B. Allow OneFS to proceed with its automatic SmartFail process to re-protect the failed node
3. C. Migrate the disks from the failed node into spare drive bays on other nodes
4. D. Initiate a manual SmartFail process on the node as it is not started automatically

Correct Answer: A

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?

1. A. SyncIQ license is required on both the source and target clusters
2. B. SyncIQ license is required on the source but not on the target cluster
3. C. SyncIQ license is required on target but not on the source cluster
4. D. SyncIQ license is included in the OneFS license; no additional license is needed

Correct Answer: A
The SynchIQ license is required on "both" the source and target clusters.

We have been engaged by a research hospital to help upgrade their Isilon installation. They currently have 12 previous generation Isilon nodes with 200TB of capacity and run on a 1Gbps network. They currently have 6 Illumina Hi-Seq Sequencers and an HPC cluster to process data. They would like to expand Isilon to 2PB of active data and 1PB of archive data. They use a third party data and metadata management service (IRODs) to stage data for analysis. The Isilon cluster is mainly used for analysis work with the HPC cluster.

1. A. InsightIQ
2. B. isi_netlogger
3. C. tcpdump
4. D. netstat

Correct Answer: A
