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?

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

A large financial services company requires a capacity expansion for retaining over 2.5 PB of document images as a cold archive.
Which Isilon node series should be recommended?

• A. X210 Series
• B. NL410 Series
• C. X410 Series
• D. HD400 Series

A European Sports TV network is considering Isilon for their Media Edit Storage for their editing workloads. They are also considering Isilon for near-line media archiving.
The network receives XDCAM HD footage which is loaded onto their existing Transcoding Storage platform. New footage that needs to be edited will be transferred from their Transcoding Storage platform to the proposed Media Edit Storage platform at the rate of ten simultaneous XDCAM HD files via FTP.
Edited files will be transferred back to the Transcoding Storage platform at the rate of ten simultaneous XDCAM HD files via FTP.
The network currently has 15 Final Cut Pro edit stations, 15 Avid edit stations. Proxy software will be used to allow Isilon to act as the storage for the Final Cut Pro and Avid media. Three of those edit stations will be performing content compositing as needed.
The network expects 70 hours of new content per week, and 50 hours of edited content per week. They intend to keep the new and edited content on the proposed Media Edit Storage as a performance tier for
30 days. They would like to retain all new and edited footage proposed Media Edit Storage as a near-line tier for two years.
In addition to the current workloads, the network expects to implement a new Media Asset Management (MAM) solution and has requested the Isilon cluster be capable of supporting 120 MBps read and 120 MBps write to support the MAM requirements.


The customer wants to be able to put completed content into a non-editable folder. However, they want to give access to an administrator to delete content if required.
What do you recommend to the customer?

• A. WORM using Compliance mode
• B. SmartLock using Enterprise mode
• C. SmartLock using Compliance mode
• D. SyncIQ with read-only mode

A customer has 10 nodes in a cluster using N+2 protection.

• A. 4
• B. 6
• C. 7
• D. 5
