— 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.
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.

B.
Repoint the engineering users to the Active Directory controller
Add 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.
Create a new pool for use by the collaboration users.
Set up Access Zones on the Isilon cluster using AD and NIS authentication.
