EMC Isilon Design Specialist Exam for Technology Architects Sample Questions:
-- Exhibit -
We have been engaged by a research hospital to help upgrade their Isilon installation. They currently have 12 previous generation Isilon nodes with 200TB of capacity and run on a 1Gbps network. They currently have 6 Illumina Hi-Seq Sequencers and an HPC cluster to process data. They would like to expand Isilon to 2PB of active data and 1PB of archive data. They use a third party data and metadata management service (IRODs) to stage data for analysis. The Isilon cluster is mainly used for analysis work with the HPC cluster.
-- Exhibit -
Currently, the workflows are being limited by the network access to the Isilon cluster.
What would result in the fastest possible network throughput?
- A. Use LACP to aggregate the network connections.
- B. Implement jumbo frames.
- C. Add four A-Series accelerator nodes.
- D. Move analysis infrastructure to dedicated 10G network.
Correct Answer: D 🗳️
Your customer has observed a degradation in response time while browsing for media files within the Production Media folder on the Isilon cluster. That directory now contains over five million files. It was confirmed that there are no network or edit station related causes.
What changes to the Isilon cluster will best accelerate the browsing performance?
- A. Add an A-Series Performance Accelerator node
- B. Upgrade network interfaces on the nodes to 10 Gbps
- C. Upgrade RAM on the nodes
- D. Add Solid State Drives (SSDs) to the nodes
Correct Answer: D 🗳️

The customer will add two more Illumina Hi-Seq Sequencers in the next 6 months.
Once these are added, what is the total amount of data from all the sequencers they can expect to add per month?
- A. 14.4 TB
- B. 4.8 TB
- C. 1.2 TB
- D. 9.6 TB
Correct Answer: D 🗳️
-- 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. Utilize SMB2.1 protocol and mount to the Isilon cluster using the Name Server (NS) record IP.
- B. Mount an NFS share to a node on the Isilon cluster, being careful to equally distribute the load across nodes.
- C. Direct all clients to use the Manufacturing DNS server and connect NFS mounts to the FQDN of the Isilon cluster.
- D. Create an FQDN for the Isilon cluster in the LMHOSTS file for each engineering system.
Correct Answer: C 🗳️
A hospital is considering using Isilon to store their long-term archive data for their PACS application. They currently have two million 17 MB studies. They expect capacity requirements to be 50% compounded growth per year. They plan to use N+2:1 protection, and would like this sized for three years of growth.Which minimum cluster configuration would meet this customer's environment?
- A. Five NL400 (1 TB drive) nodes
- B. Three X400 (3 TB drive) nodes
- C. Five X200 (3 TB drive) nodes
- D. Four NL400 (2 TB drive) nodes
Correct Answer: A 🗳️
