• A.2 KB
• B.4 KB
• C.6 KB
• D.8 KB

By default, how much space needs to be reserved for snapshots on an Isilon cluster?

• A.10% of the cluster

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 use Hadoop to analyze the informationdirectly over HDFS
• 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 ingest the information into Hadoop foranalysis
• D.Write the CDRs directly to an Isilon cluster with an NFS mount, then use Hadoop to analyze theinformation directly over HDFS

If a file is 4 KB in size, how much space is consumed for file data when it is written to the Isilon cluster?

• A.4 KB
• B.16 KB
• C.8 KB
• D.32 KB
