FREE DELL EMC E20-555 Real Dumps Questions

1. A customer is planning an Isilon deployment for use with their Hadoop environment.
What is one advantage of using Isilon as the HDFS layer?

2. A customer has an Isilon cluster that they want to simplify a Hadoop workflow. The workflow analyzes large amounts of log data written to storage using FTP and results are viewed by Microsoft Windows clients?
How can this be achieved?

3. A company wants to reduce the footprint in their data center. They recently completed a proof of concept with Hadoop using Direct Attached Storage (DAS) for their Big Data initiative. You have determined that incorporating an Isilon cluster into their Hadoop environment would help in reducing this footprint.
Which Hadoop components can be consolidated onto the Isilon cluster to reduce the footprint?

4. Your customer is moving from a Restaurant/Bar business model to a Restaurant/Casino business model. You are helping architect the upgrade of a current 4-node X200 48 TB Isilon cluster, with 50% utilized for their video surveillance operations. They want to upgrade from 15 FPS (NTSC) in H. 264 codec, with a 15 days retention policy to 30 FPS (NTSC) in H. 264 codec, with a 30 days retention policy.
How many nodes of the same type will you need to add in order to meet the required changes and not exceed 70% raw capacity?

Which storage capacity would be the best suited to meet the required changes and utilize 65-75% capacity?

6. You are working with a healthcare company that is interested in replacing all the backend storage for their PACS system.
In general, how should the solution be presented to the customer?

7. 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?

8. A four-node Isilon cluster is being used in a Hadoop workflow with a parity protection of N+2:1. The HDFS protocol has been enabled and is being used to access data.
How many additional copies of data are written into the Isilon cluster using HDFS?

9. Your customer has a new business unit. They are gathering web log files to be analyzed. They are using Hadoop to do the analysis of the logs. The IT department is centrally storing the log files on a 5-node Isilon cluster. They have enabled the Hadoop cluster to access the files directly on the Isilon storage. The nodes are X400's with two SSD drives in each node and 96GB of RAM.
How many DataNodes does the Isilon cluster have?

10. 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 nodes for this solution?

11. Your customer has observed a degradation in response time while browsing for media files within the Production Media folder of 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?

12. While validating the value (VTV) with a large educational customer, they have decided they would like to add a Disaster Recovery (DR) site to their existing Isilon environment. The existing cluster contains six X-Series nodes. They plan to have all workflows replicated to the DR site and both clusters will have identical shares, exports, and user authentication. The customer would like to test DR failover every six months by running their production environment from the DR site.
What would you recommend for the DR solution?

13. A hospital is considering using Isilon to store their archived medical images and Genomic Sequencing data. They currently have 56 TB of PACS images and 24 TB of genomic data, and expect to double their capacity requirements this year. They will replicate to a DR cluster, and plan to use N+2 protection. The production workload needs to be run at either site.
Which minimum cluster configuration, at each site, including software, would meet this customer's environment?

14. A hospital is considering using Isilon to store their long-term archive data for their GE 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?

15. Which protocols are supported by Isilon OneFS for file access?

16. Which Isilon OneFS protection level allows you to withstand two drive failures but no more than one complete node failure?

17. An Isilon customer expressed an interest in more effectively managing their storage. Specifically, they would like to plan for future growth.
Which tool would allow the customer to forecast capacity requirements?

18. Which Isilon feature provides the ability to build a cluster using different node types and tiers to meet a customer's business objectives?

19. At which level can retention periods be applied with Isilon SmartLock?

20. A customer is trying to get Isilon SyncIQ to run on the two clusters they just purchased. However, they are experiencing some problems. They have asked you to explain how the SyncIQ licensing works.
What information can be provided to the customer?
