Which service daemon do FTP and FTPS use to transfer files to and from the cluster?

• A.ftpd
• B.ftpsd
• C.sftpd
• D.vsftpd

A customer wants an N+3 protection level on their cluster. What is the minimum number of nodes they need to achieve that level of protection?

• A.3
• B.6
• C.7
• D.8

An administrator recently installed InsightIQ to gather cluster statistics, and wants to look at file system usage (such as the number of files in a directory). However, currently no file system statistics are displayed in InsightIQ after 24 hours. Use of the cluster is moderate, and occurs 24 hours per day.
What job for InsightIQ should the administrator modify to successfully report these statistics?

• A.Change priority to 7 and job impact to Medium for SmartPools
• B.Change priority to 4 and job impact to Medium for FSAnalyze
• C.Change priority to 3 and job impact to Low for MultiScan
• D.Change priority to 1 and job impact to High for Collect

Which Isilon feature provides the ability to build a cluster using different node types and tiers to meet a customer's business objectives?

• A.SmartPools
• B.SmartQuota
• C.SmartConnect
• D.SnapshotIQ
  Smartpools is the licensed feature that enables using different node types.

A potential customer requires 800 TB of usable capacity to store medical images for their network of health clinics. The IT department has limited staff and currently manages four storage arrays from other vendors. During a meeting with the Director of IT you learn that the company is considering a solution from a competitor of EMC using two of the existing arrays and two new arrays.
Which Isilon capabilities would show a better ROI for the customer?

• A.Isilon has 6%-12% less filesystem overhead than traditional clustered filesystem solutions.With a single filesystem and virtual capacity for drive and node failures, Isilon utilization is typically 80% or higher.Isilon utilization is typically 80% or higher due to use of a single filesystem and virtual capacity for drive and node failures.
• B.Forward Error Correction overhead is 7% lower than traditional RAID.Isilon has 6%-12% less filesystem overhead than traditional clustered filesystem solutions.According to an IDC study, Isilon improves IT productivity by nearly 50% compared to traditional competitors.
• C.Isilon has 15%-20% less overhead than traditional clustered filesystems.According to an IDC study, Isilon utilization is nearly 50% higher than traditional competitors.Isilon QOS headroom and multiple node pools ensures consistent performance up to 80% utilization.
• D.With a single filesystem and virtual capacity for drive and node failures, Isilon utilization is typically 80% or higher.OneFS compression results in higher effective capacity within the cluster.Traditional clustered filesystems require 4%-10% internal overhead compared to Isilon virtual capacity.
