EMC Isilon Design Specialist Exam for Technology Architects Sample Questions:
1. You are sizing an Isilon cluster for a new customer. Analyzing their workflow you determine that they have a large block random read workload.What is the most important factor to consider when sizing this solution?
A) IOPS
B) Bandwidth
C) Headroom
D) Latency
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 Downstream hand-off Design to meet customer expectations
D) Solutions Document Balance technical and business requirements Provide options Practical vs. theoretical implementations
3. A cost-conscious customer is exploring Isilon for their PACS archive. The workflow consists of one hundred cases a day, each including fifty 60MB image files. However, each image will have five-hundred 64kB metadata files associated with it. They currently have six years worth of archived data. They will need to migrate to the new solution and they need to plan for an additional three years of archive capacity.
Which solution would you recommend to fit their capacity needs?
A) 24 X-Series nodes with N+3 protection policy providing 2597 TiB of useable capacity
B) 18 NL-Series nodes with N+2:1 protection policy providing 2078 TiB of useable capacity
C) 12 NL-Series nodes with N+2 protection policy providing 1300 TiB of useable capacity
D) 24 NL-Series nodes with N+3 protection policy providing 2597 TiB of useable capacity
4. When conducting high-level interviews with stakeholders of a project, what are the key questions that should be asked?
A) How much usable storage are you looking for? What client OS will access this storage? Which applications will access this storage?
B) Which backup application is in use today?
What is your change rate?
How many clients will connect to the cluster?
C) Who are the application owners?
How much usable storage is needed?
What applications will be accessing the storage?
How many users are in your Active Directory?
D) What does your network architecture look like?
Do you have existing NAS infrastructure?
Do you have 10Gb or 1Gb ethernet?
Which applications will access this storage?
5. -- 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.
