A telecommunications company has a substantial amount of data. This data is being created by networkelements within their environment.
The company wants to change the way the network element's Call Detail Records (CDR) are stored andanalyzed. The existing infrastructure consolidates all of the CDRs into a table structure, and then ingests theminto a large database. Once ingested, a query engine accesses the database and performs analysis on thesefiles. The system is functional; however, since the amount of CDRs generated will increase exponentially overthe 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 oftime 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 workwithin the Hadoop environment.
What would be the best recommendation to the customer for the workflow of Hadoop with Isilon?

• A. Copy the CDRs from the source to an Isilon cluster with NFS, then ingest the information into Hadoop foranalysis
• B. Write the CDRs directly to an Isilon cluster with an NFS mount, then ingest the information into Hadoop withNFS, then analyze
• C. Copy the CDRs from the source to an Isilon cluster with NFS, then use Hadoop to analyze the informationdirectly over HDFS
• D. Write the CDRs directly to an Isilon cluster with an NFS mount, then use Hadoop to analyze theinformation directly over HDFS

A customer is looking for a new storage solution to handle their growing storage requirements. The systemshould be able to cover storage needs for the next three years. The environment consists of 100 TBs of filesystem data spread across five file systems. On average, the file systems grow 1 TB a month. In addition, theyhave a large VMware cluster supporting 200 VMs and a highly transactional database.
The customer is looking for a solution that would provide good performance, scalability, manageability, and becost-effective. The sales team is looking to you to recommend a solution. Which recommendation will meet thecustomer's requirements?

• A. Isilon cluster and scale-out as required
• B. Isilon for file system data, and a VNX for DB and VMware workloads
• C. VMAX with FAST VP and a NAS Gateway
• D. VNX Unified platform with FAST Cache

Your customer is moving from a Restaurant/Bar business model to a Restaurant/Casino business model. Youare helping architect the upgrade of a current 4-node X200 48 TB Isilon cluster, with 65% utilized for theirvideo surveillance operations. They wish to achieve the following:
Upgrade from 1280 x 720 resolution, with a 15 days retention policy, to 2048 x 1536 resolution with a 30 daysretention policy.
What is the minimum number of nodes of the same type will you need to add in order to meet the requiredchanges and not exceed 70% raw capacity?

• A. 18 nodes
• B. 6 nodes
• C. 10 nodes
• D. 14 nodes

A Media and Entertainment company is considering changing from 2K resolution to 4K resolution.
They will continue to use the DNxHD 220 codec.
Assuming everything else stays the same, how will this change affect storage?

• A. Storage will be half as large
• B. Storage will be twice as large
• C. Storage will be four times as large
• D. Storage requirements will not change
