Question 180/209

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. NL400 with 48GB RAM and no SSDs per node

B. X400 with 96GB of RAM and no SSDs per node

C. X200 with 24GB of RAM and 1.2TB of SSD per node

D. X400 with 24GB RAM and 1.6TB of SSD per node
