— 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.

Which configuration changes would you recommend for the Engineering users?

A.
Direct all clients to use the Manufacturing DNS server and connect NFS mounts to the FQDN of
the Isilon cluster.

B.
Mount an NFS share to a node on the Isilon cluster, being careful to equally distribute the load
across nodes.

C.
Utilize SMB2.1 protocol and mount to the Isilon cluster using the Name Server (NS) record IP.

D.
Create an FQDN for the Isilon cluster in the LMHOSTS file for each engineering system.
