EMC Isilon Design Specialist Exam for Technology Architects 認定 E20-554 試験問題：

問題 #1

You set up a meeting to gather information on a new project with the IT manager and plan to use a workflow profile assessment (WPA) to document the requirements.
Why is it recommended to talk to as many stakeholders as possible?

A. Helps downstream personnel, such as implementation and delivery, to have a clearer understanding of the requirements.
B. Using the WPA tool will give you the best "big picture" to see things such as block size, de-dupe, file size and volumes.
C. Completing this document gives sales a list of who the stakeholders are at customer site.
D. Using workflow profile enables sales to take this information to EMC consulting for review to validate the configuration.

問題 #2

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

問題 #3

You are designing a new Isilon system to store mobile device video clips. The files average 800MB in size and the application team tells you to plan for up to 15,000 new files per day. The product manager for this new service wants enough capacity for the first year and reminds you that response time for storing and retrieving the files is important for customer satisfaction.
The files will be accessed frequently for the first 48 hours after creation, and then very infrequently after seven days. You plan to use N+2:1 protection, and will configure a SmartPools policy to move inactive files to an archive tier within the cluster.
Which configuration best fits the project requirements?

A. 4 x X400 nodes with 1TB drives; 36 x NL400 nodes with 4TB drives
B. 38 x X400 nodes with 4TB drives and SSD
C. 4 x S200 nodes with SSD; 45 x NL400 nodes with 3TB drives
D. 4 x X200 nodes with SSD; 36 x NL400 nodes with 4TB drives

問題 #4

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. Latency
B. Bandwidth
C. Headroom
D. IOPS

問題 #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 nodes with SSD to help with connections
C. Add more network switches to increase the number of connections
D. Add RAM to the nodes to offset concurrent client connections
