2. -- 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.
The customer provides the following environment summary from the engineering firm's recently departed IT staff:
20 TB of Home Directory data
100 TB of active CAD projects 400 TB of archived data stored on tape at an offsite warehouse
-- Exhibit -
The CIO approaches you with a new requirement. They would like to reuse the tape library that was previously used for archiving to now be used to back up some of their data.
What do you recommend to the Director of IT as the best architecture to achieve this goal?

A) Implement a Backup Accelerator and use the internal backup software within the Isilon cluster to move data to the tape library.
B) Connect the Tape Library via Fibre Channel to the Isilon cluster and use a third party backup software to initiate an NDMP backup to an accelerator.
C) Use a Backup Accelerator with SyncIQ to push the data to the tape library via the Fibre Channel ports on the accelerator.
D) Use a third party backup software and have the Isilon cluster convert the data to LTFS so it can be stored to the tape library.

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

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

4. Refer to the exhibit.

A large hospital chain has approached you to redesign their storage infrastructure. The head of IT believes their requirement is for 100 TB of RAW capacity. They want to consolidate their PACS, file shares and home directories onto one cluster and require very fast enumeration of the directories. The following are the notes from meetings with the department heads.Which is the best cluster configuration that meets the customer's requirements?

A) 3 x S-Series nodes using SmartPools and 3 x NL-Series nodes for Archive
B) 5 x S-Series nodes
C) 3 x NL-Series nodes using SynqIQ to 3 x NL-Series nodes
D) 4 x X-Series nodes using SynqIQ to 4 x NL-Series nodes

5. 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) Add an A-Series Performance Accelerator node
C) Upgrade network interfaces on the nodes to 10 Gbps
D) Upgrade RAM on the nodes
