EMC Isilon Design Specialist Exam for Technology Architects Sample Questions:

1. You are reviewing an opportunity with a trusted advisor. You both discover gaps in the initial solution design.
Each iterative discussion with the customer helps you define the solution better. The documents produced capture the customer's requirements.
What else needs to occur to refine the sizing considerations?

A) Provide the CIO with the findings and gain commitment to a Proof of Concept.
B) Review you assumptions and ask the customer what business issue you're solving.
C) Validate the Workflow Profile Assessment and test the solution against your findings.
D) Complete your Solution Design Document and forward to EMC consulting.

2. When designing Isilon solutions, what issues should you pay special attention to?

A) Avoid being too enthusiastic over the technology Balance technical and business requirements Provide options Design to meet customer expectations
B) Workflow Document Solutions Document Application types Data strategy
C) Solutions Document Balance technical and business requirements Provide options Practical vs. theoretical implementations
D) Solutions Document Balance technical and business requirements Downstream hand-off Design to meet customer expectations

3. Your customer uses an existing Isilon cluster consisting of five NL-Series nodes to source broadcast media files for playback and streaming. The customer reports that the playback pauses and stutters regularly. It has been confirmed that there are no network or playback system issues.
Which is the appropriate choice to resolve the playback issues?

A) Enable Level 2 caching
B) Add three or more S-Series nodes
C) Enable SmartConnect Advanced
D) Upgrade OneFS to the latest version

4. While validating the value (VTV) with a large educational customer, they have decided they would like to add a Disaster Recovery (DR) site to their existing Isilon environment. The existing cluster contains six X-Series nodes. They plan to have all workflows replicated to the DR site and both clusters will have identical shares, exports, and user authentication. The customer would like to test DR failover every six months by running their production environment from the DR site.
What would you recommend for the DR solution?

A) SyncIQ and identical cluster at the DR site
B) Equal number of S-Series nodes at the primary site
C) SyncIQ and NL-Series nodes at the DR site
D) SmartConnect and NL-Series nodes at the primary site

5. -- 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 -
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) Create an FQDN for the Isilon cluster in the LMHOSTS file for each engineering system.
C) Mount an NFS share to a node on the Isilon cluster, being careful to equally distribute the load across nodes.
D) Utilize SMB2.1 protocol and mount to the Isilon cluster using the Name Server (NS) record IP.
