You are assisting a customer with creating an Isilon solution that will address their needs while remaining cost-effective. The customer environment consists entirely of archive data. The data in their enterprise produces very little I/O and is only occasionally accessed.
Which Isilon storage node type will meet the customer's needs?

• A.NL-Series node
• B.S-Series node
• C.Performance Accelerator node
• D.X-Series node

Your customer has several departments that want separate access to the cluster so they can use their individual authentication methods. Two of the departments will use NFS and two will use SMB to access the cluster.What would you recommend?

• A.Create two separate Access Zones for the NFS clients, and use the System Zone for the SMB clients.
• B.Have all clients access the System Zone, and use RBAC to control authentication.
• C.Create separate Access Zones for both the SMB and NFS clients.
• D.Create two separate Access Zones for the SMB clients, and use the System Zone for the NFS clients.

A company wants to reduce the footprint in their data center. They recently completed a proof of concept with Hadoop using Direct Attached Storage (DAS) for their Big Data initiative.

• A.DataNode and NameNode
• B.DataNode and ComputeNode
• C.ComputeNode and NameNode
• D.NameNode and TaskTracker

Your customer has a new business unit. They are gathering web log files to be analyzed. They are using Hadoop to do the analysis of the logs. The IT department is centrally storing the log files on a 5-node Isilon cluster. They have enabled the Hadoop cluster to access the files directly on the Isilon storage. The nodes are X400's with two SSD drives in each node and 96GB of RAM.How many DataNodes does the Isilon cluster have?

• A.Three
• B.Five
• C.Two
• D.One
