EMC Isilon Design Specialist Exam for Technology Architects Sample Questions:

1. -- 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 -
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) 1.2 TB
B) 4.8 TB
C) 9.6 TB
D) 14.4 TB

2. You meet with the IT Director of a large single site campus. The IT department has recently taken over Physical Security from the facilities department and plans a complete overhaul of the surveillance solution. They are looking to you as a storage architecture expert to provide the correct amount of storage needed. The IT Director asks you what items they need to provide in order to size this solution.What data do you require from the customer?

A) Pixel count Video CODEC Color sampling Frames per second (fps) Number of devices Retention time
B) Pixel count Video CODEC Color sampling Frames per second (fps) Number of devices Video management system Evidence collection period
C) Bit rate per camera Camera manufacturer Video management system Retention time
D) Video resolution Video CODEC Frames per second (fps) Number of devices Retention time

3. A media and entertainment company has asked for help in creating a new Video On Demand (VOD) storage system. The storage would be delivered to 5000 subscribers simultaneously. They would like to store 5000 hours of full length, High Definition (HD) movies.
What would be the best price-to-performance node(s) for this solution?

A) Mixed X400 48GB RAM and NL400 24GB
B) X400 with no SSD and 96GB RAM
C) X400 with 1.6TB SSD and 24GB RAM
D) X200 with no SSD and 48GB RAM

4. 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) WORM requirements Network ports for replication Snapshots for user restores
C) Default cluster protection level Backup windows and processes Concurrency of user access
D) Default cluster protection level Additional directory level protections Snapshots and replication

5. 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) Validate the Workflow Profile Assessment and test the solution against your findings.
C) Review you assumptions and ask the customer what business issue you're solving.
D) Complete your Solution Design Document and forward to EMC consulting.
