EMC E20-554 real exam prep : Isilon Design Specialist Exam for Technology Architects

-- Exhibit -
A European Sports TV network is considering Isilon for their Media Edit Storage for their editing workloads. They are also considering Isilon for near-line media archiving.
The network receives XDCAM HD footage which is loaded onto their existing Transcoding Storage platform. New footage that needs to be edited will be transferred from their Transcoding Storage platform to the proposed Media Edit Storage platform at the rate of ten simultaneous XDCAM HD files via FTP. Edited files will be transferred back to the Transcoding Storage platform at the rate of ten simultaneous XDCAM HD files via FTP.
The network currently has 15 Final Cut Pro edit stations, 15 Avid edit stations. Proxy software will be used to allow Isilon to act as the storage for the Final Cut Pro and Avid media. Three of those edit stations will be performing content compositing as needed.
The network expects 70 hours of new content per week, and 50 hours of edited content per week.
They intend to keep the new and edited content on the proposed Media Edit Storage as a performance tier for 30 days. They would like to retain all new and edited footage proposed Media Edit Storage as a near-line tier for two years.
In addition to the current workloads, the network expects to implement a new Media Asset Management (MAM) solution and has requested the Isilon cluster be capable of supporting 120 MBps read and 120 MBps write to support the MAM requirements.

Refer to the exhibit.

Based on the described use of the cluster, what are the customer's capacity requirements?

• A. 30 days retention: 5 TB; 2 years retention: 120 TB
• B. 30 days retention: 1 TB; 2 years retention: 24 TB
• C. 30 days retention: 15 TB; 2 years retention: 360 TB
• D. 30 days retention: 30 TB; 2 years retention: 720 TB

The customer wants to be able to put completed content into a non-editable folder. However, they want to give access to an administrator to delete content if required. What do you recommend to the customer?

• A. SyncIQ with read-only mode
• B. WORM using Compliance mode
• C. SmartLock using Compliance mode
• D. SmartLock using Enterprise mode

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. 18 NL-Series nodes with N+2:1 protection policy providing 2078 TiB of useable capacity
• B. 24 NL-Series nodes with N+3 protection policy providing 2597 TiB of useable capacity
• C. 24 X-Series nodes with N+3 protection policy providing 2597 TiB of useable capacity
• D. 12 NL-Series nodes with N+2 protection policy providing 1300 TiB of useable capacity

You are asked to size a cluster for a file sharing environment. nfsstat indicates that no more than 10% of the requests are namespace operations (e.g. GETADDR, SETADDR). There will be 10,000 active Linux users, connecting over NFS.
Which cluster configuration would you recommend?

• A. Ten X200 (27 TB) 48 GB RAM, 600 GB SSD, N+2:1
• B. Eight X200 (36 TB) 24 GB RAM, no SSD, N+2:1
• C. Ten X400 (60 TB) 48 GB RAM, 2.4 TB SSD, N+2:1
• D. Five X400 (120 TB) 96 GB RAM, 2.4 TB SSD, N+2

You have had several discussions with your customer in the processor design industry. They have stated that they want a Scale-Out NAS platform for their design environment. Their most significant responses were "We have 125 design engineers accessing large diagrams and we need high throughput to support them. Can we also get the highest performance available? We need to stay ahead of our competitors." Other areas you discussed were their data retention policies and workflow after the chip design is completed. They plan to archive the design files but the files must stay on line.
What is your initial node recommendation?

• A. X-Series nodes for the active diagrams and NL 400 nodes for the archives
• B. X-Series nodes with SSD for the active diagrams and NL nodes for the archives
• C. S-Series nodes for the active diagrams and NL Series nodes for the archives
• D. A-Series nodes for the active diagrams and X-Series nodes for the archives.
