Isilon Infrastructure Specialist Exam for Technology Architects Sample Questions:

1. How can an Isilon cluster simplify a Hadoop workflow that analyzes large amounts of log data written to storage using FTP and where results are viewed by Microsoft Windows clients?

A) FTP, SMB, and HDFS NameNode and DataNode protocol support on the same file system enables each workflow step to access data from the same location avoiding data migration.
B) SyncIQ migrates the log data between an Isilon cluster and another Hadoop cluster, retrieves results from the Hadoop cluster, and stores them in an SMB share.
C) FTP and SMB protocol support covers log ingest and Windows clients; SmartPools will stub to HDFS helping to reduce the frequency of external data migration.
D) SmartConnect directs clients to an external Hadoop NameNode and to SMB shares so data ingest, analytics, and results phases are transparently directed.
