A potential customer requires 4 PB of usable capacity to store media files. The workloads are a combination of streaming video delivery and long term archive of video assets.
There is very little space available in the customer's datacenter, so physical density is very important. The customer is concerned about performance impact and potential data loss when using 3 TB or larger drives.
What Isilon capabilities can address the customer's concerns?

• A. Isilon does not perform rebuilds - data reprotection is typically 2x-3x faster than traditional RAID
  rebuilds.
  N+3 and N+4 Protection Levels exceed traditional RAID6 availability.
  Data redistribution runs faster with more nodes in the cluster.
• B. Isilon nodes have more drives per rack unit so fewer shelves are required.
  Proactive hot sparing eliminates most drive rebuilds.
  N+3 and N+4 Protection Levels exceed traditional RAID6 availability.
• C. N+3 and N+4 Protection Levels exceed traditional RAID6 availability.
  Proactive hot sparing eliminates most drive rebuilds.
  Endurant Cache reduces the overhead for write operations.
• D. Isilon does not perform rebuilds - data reprotection is typically 2x-3x faster than traditional RAID
  rebuilds.
  Data recovery is consistent, taking the same amount of time regardless of cluster size.
  Isilon 'short strokes' 4TB drives to reduce rebuild time.

You meet with the IT Director of a large single site campus. The IT department has recently taken over Physical Security from the facilities department and plans a complete overhaul of the surveillance solution. They are looking to you as a storage architecture expert to provide the correct amount of storage needed. The IT Director asks you what items they need to provide in order to size this solution.What data do you require from the customer?

• A. Pixel count Video CODEC Color sampling Frames per second (fps) Number of devices Retention time
• B. Pixel count Video CODEC Color sampling Frames per second (fps) Number of devices Video management system Evidence collection period
• C. Bit rate per camera Camera manufacturer Video management system Retention time
• D. Video resolution Video CODEC Frames per second (fps) Number of devices Retention time

Your customer has observed a degradation in response time while browsing for media files within the Production Media folder on the Isilon cluster. That directory now contains over five million files. It was confirmed that there are no network or edit station related causes.
What changes to the Isilon cluster will best accelerate the browsing performance?

• A. Add Solid State Drives (SSDs) to the nodes
• B. Upgrade network interfaces on the nodes to 10 Gbps
• C. Add an A-Series Performance Accelerator node
• D. Upgrade RAM on the nodes

A potential customer has about 540TB of NetApp running in ONTAP 7-Mode. They are willing to let you gather some workload data. They have LDAP and Active Directory authentication and primarily Windows Clients. They are very interested in Automated Tiering and Large Scale Archives. They are not certain about the workflows from the Marketing Department. The Content Team will only say they need to acquire 300 TB within 90 days. They do not know the average file size or the number of aggregates they are managing.
Which tools would you use to gather information to do your Isilon sizing?

• A. Isilon Insight IQ, OnCommand Insight, and nfsstat
• B. MiTrendWPA ,Autosupport, and PerfCollect
• C. Wireshark, isi statistics, and iostat
• D. isi status, isi_netlogger, and PerfMon
