EMC Isilon Design Specialist Exam for Technology Architects Sample Questions:

1. -- 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) 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.
B) Implement a Backup Accelerator and use the internal backup software within the Isilon cluster to move data to the tape library.
C) Use a Backup Accelerator with SyncIQ to push the data to the tape library via the Fibre Channel ports on the accelerator.
D) 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.

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

3. A healthcare services provider is implementing an X-Series cluster. Currently they have approximately 200 customers and they are growing at 30% per year. They have 200 TB of storage utilized. Health Insurance Portability and Accountability Act (HIPAA) regulations require they keep all patient data for seven (7) years. They would like to keep all genomic sequencing data stored with N+3 protection, not to exceed 75% utilization.
What is the minimum initial configuration you would recommend?

A) 13 X400 nodes; 1 TB drives
B) 6 X400 nodes; 4 TB drives
C) 13 X200 nodes; 3 TB drives
D) 7 X400 nodes; 1 TB drives

4. Refer to the exhibit.

Which tool was used to create this output and what is the most significant characteristic?

A) isi_netlogger and moderate metadata read operations
B) nfsstat and write-intensive access
C) nfsstat and read-intensive access
D) iostat and write-intensive access

5. A customer has eight X400 24GB RAM nodes that support 400 client connections. They will be adding 400 more clients in the next few months. They are looking at adding an A-Series node to the cluster to help with client connections.Before they start adding client connections, what hardware change do you recommend?

A) Add an A100 node to offset concurrent client connections
B) Add RAM to the nodes to offset concurrent client connections
C) Add more network switches to increase the number of connections
D) Add nodes with SSD to help with connections
