-- Exhibit --
A large manufacturing company is an existing Isilon customer with a cluster consisting of four NL400 nodes with 4TB drives. The cluster is using N+2:1 protection level and the file system shows that it is 60% utilized. Home directories and file shares comprise 75% of the existing content and the remainder is inactive deep archive. The company has 1,000 employees using Windows and Mac clients participating in a single Active Directory (AD) forest.
During a meeting with the CIO and Director of IT you discuss the company's recent acquisition - an engineering firm that specializes in Computer Aided Design (CAD). The engineering firm has 400 UNIX workstations that produce technical drawings which are currently stored on another vendor's SAN solution. The all UNIX environment uses NIS for authentication and name resolution. They do not currently use DNS or LDAP. The engineering company has an old storage system that has been experiencing problems and the CIO would like you to migrate the data onto the Isilon cluster. The CIO would like to eliminate all tape and recover the data onto disk.
The CIO is concerned about security of the company's intellectual property, especially with the rapid adoption of mobile devices and external cloud content sharing services such as DropBox, Egnyte, and SugarSync. They would like to implement an alternative that provides external file sharing and mobile device synchronization while maintaining security control over the company's data.
The Director of IT reports that users are storing non-work related content on the Isilon cluster. They would like to limit the amount of capacity that each user can consume in their home directory and want to ensure you provide the capability to easily visualize which users are over their allotment.The company's Windows users currently leverage Windows Shadow Copy to recover files that have been accidentally deleted. The IT department wants to ensure that Mac and incoming UNIX clients have the same functionality.
The Director of IT also mentions that users are reporting slow response times when browsing their home directories and shared folders. They are concerned that Isilon cannot scale to support their combined requirements.

What steps would you recommend to the IT Director to allow for collaboration between the engineering company and the manufacturing company?

• A.Create a new pool for use by the collaboration users.Set up Access Zones on the Isilon cluster using AD and NIS authentication.
• B.Repoint the engineering users to the Active Directory controllerAdd the users to the appropriate Active Directory security group.
• C.Upload a collaboration user csv file into the cluster with usernames and passwords for the collaboration directory.
• D.Set up Access Zones on the Isilon cluster using Active Directory (AD) and NIS authentication.Create directories and apply user group permissions from AD and NIS for each collaboration team.

When a client requests a file to read from an Isilon cluster, in which order does the read operation access the hardware in a node?

• A.L1 cache, L2 cache, disk
• B.L2 cache, L1 cache, disk
• C.Endurant Cache, L1 cache, disk
• D.Disk, L2 cache, Endurant Cache

A NetApp customer is considering Isilon. They use their filers for UNIX home directories, and would like to see a suggested configuration that would meet their needs.
What would you do to help size this cluster?

• A.Ask them to install InsightIQ and collect data from the filer, then import to SQL for analysis
• B.Ask for an autosupport file and upload it to MiTrends to generate a workflow profile
• C.Ask for the output from nfsstat and upload it to MiTrends to generate a workflow profile
• D.Use tcpdump and upload the output file to MiTrends to generate a protocol analysis

Your customer is looking for a storage solution that will be able to store seven million 3 MB files which are written and seldom accessed. Read and write operations are both completed by a web-based application, which requires 1.3 Gbps throughput. The customer's network has not been upgraded in many years, so the network interfaces are 1 Gbps.
What would be the best solution for this network configuration?

• A.Use LACP to aggregate the network ports on each node.
• B.Use jumbo frames to compensate for the 1GB Core network.
• C.Aggregate Infiniband (IB) ports across all nodes.
• D.Bond EXT-0 across all nodes.

What is the sector size of an Isilon 8 TB drive?

• A.1024 bytes
• B.4096 bytes
• C.512 bytes
• D.2048 bytes
