EMC E20-554 Exam Syllabus Topics:

EMC Isilon Design Specialist Exam for Technology Architects Sample Questions:

1. You meet a customer for the first time. They explain that their current environment for NAS does not meet their needs. You want to make sure that Isilon is a good fit for their needs.
What would be a good prequalifying question to ask?

A) What protocols are accessing your NAS?
B) How many users are in your Directory Services?
C) Is your datacenter ISO9001 compliant?
D) What application are you using to create directories?

2. Your customer purchased an Isilon cluster with eight X400 nodes for Home Directories. Your follow-up discussions have uncovered an opportunity to expand the cluster to support the Legal Department. As you prepare to complete the Workflow Profile Document, you meet with the customer to discuss data protection.
Which key areas should you address?

A) Protocols (SMB, NFS, FTP, HTTP, HDFS) Authentication and Directory Services Performance and latency concerns
B) Default cluster protection level Additional directory level protections Snapshots and replication
C) Default cluster protection level Backup windows and processes Concurrency of user access
D) WORM requirements Network ports for replication Snapshots for user restores

3. -- 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 -
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 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) 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.

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

A) Workflow Document Solutions Document Application types Data strategy
B) Avoid being too enthusiastic over the technology Balance technical and business requirements Provide options Design to meet customer expectations
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

5. A customer plans to consolidate 200 TB of digital images and video content. Performance is important for recently created files. However, the customer wants any content that has not been accessed within 30 days to be stored in the cluster at a much lower cost because performance is no longer critical.Which Isilon configuration should be recommended?

A) S-Series nodes, X-Series nodes, and SmartPools
B) NL-Series nodes and SmartLock
C) X-Series nodes and SmartQuotas
D) X-Series nodes, NL-Series nodes, and SmartPools
