11. A large manufacturing company is an existing Isilon customer with a cluster consisting of four NL400 nodes with 4TB drives. The cluster is using N+2:1 protection level and the file system shows that it is 60% utilized. Home directories and file shares comprise 75% of the existing content and the remainder is inactive deep archive. The company has 1,000 employees using Windows and Mac clients participating in a single Active Directory (AD) forest.

During a meeting with the CIO and Director of IT you discuss the company's recent acquisition - an engineering firm that specializes in Computer Aided Design (CAD). The engineering firm has 400 UNIX workstations that produce technical drawings which are currently stored on another vendor's SAN solution. The all UNIX environment uses NIS for authentication and name resolution. They do not currently use DNS or LDAP. The engineering company has an old storage system that has been experiencing problems and the CIO would like you to migrate the data onto the Isilon cluster. The CIO would like to eliminate all tape and recover the data onto disk.

The CIO is concerned about security of the company's intellectual property, especially with the rapid adoption of mobile devices and external cloud content sharing services such as DropBox, Egnyte, and SugarSync. They would like to implement an alternative that provides external file sharing and mobile device synchronization while maintaining security control over the company's data.

The Director of IT reports that users are storing non-work related content on the Isilon cluster. They would like to limit the amount of capacity that each user can consume in their home directory and want to ensure you provide the capability to easily visualize which users are over their allotment. The company's Windows users currently leverage Windows Shadow Copy to recover files that have been accidentally deleted. The IT department wants to ensure that Mac and incoming UNIX clients have the same functionality.

The Director of IT also mentions that users are reporting slow response times when browsing their home directories and shared folders. They are concerned that Isilon cannot scale to support their combined requirements.

The customer provides the following environment summary from the engineering firm's recently departed IT staff: - 20 TB of Home Directory data - 100 TB of active CAD projects - 400 TB of archived data stored on tape at an offsite warehouse

Which configuration changes would you recommend for the Engineering users?

12. While considering expanding a current Isilon cluster, what tool or report can be used to investigate current file sizes used on the cluster?

13. For concurrent I/O, how do SmartCache and Endurant Cache differ?

14. Which feature provides automated data efficiency improvements without user intervention?

15. A company needs to have their data asynchronously replicated. They also need to maintain a daily copy of the data for a week at the target side to enable fast recovery of files. They decide to purchase two Isilon clusters. They do not want to spend money unnecessarily.

Which licenses must they acquire?

16. How does the HealthCheck tool benefit daily PowerScale operations?

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

18. A PowerScale cluster is configured with SmartConnect zones using dynamic IP address allocation. Failback is enabled.

If there is a node failure, what happens to the IP address?

19. When designing an Isilon cluster for content creation workflows in the Media and Entertainment (M&E) vertical, what type of workflows must you consider?

20. A telecommunications company has a substantial amount of data. This data is being created by network elements within their environment. The company wants to change the way the network elements Call Detail Records (CDR) are stored and analyzed.

The existing infrastructure consolidates all of the CDRs into a table structure, and then ingests them into a large database. Once ingested, a query engine accesses the database and performs analysis on these files.

The system is functional; however, since the amount of CDRs generated will increase exponentially over the next year, the company is open to alternatives for storing and analyzing these records. In evaluating alternatives, the key requirements are to reduce cost, the amount of storage, and the amount of time to analyze the data.

The customer would like to use Hadoop to analyze the CDRs. After you have conducted an assessment of the workflow, you have recommended an Isilon Cluster to work within the Hadoop environment.

Which protocols would be the best fit when using Isilon for this customer's Hadoop workflow?

21. During initial configuration of a PowerScale cluster, OneFS creates a network using the default internal network interface without a failover option.

What is the default back-end network interface used?

22. What should be avoided when designing snapshot schedules?

23. Which OneFS process protects file system structures against corruption using 32-bit CRC checksums?

24. One of your customers is interested in a PowerScale Gen6 solution. They have provided basic solution requirements, but their security policies do not allow them to perform detailed data collection for infrastructure and workload analysis.

Which tool should you use to design the new PowerScale solution?

25. You are gathering information to design a PowerScale solution.

Which factors are included in the Top 10 qualification questions?

26. Refer to the exhibit.

During a requirements gathering meeting, the customer identified a desire to use a codec for editing content that will take up the least amount of space on their Isilon cluster. The content is 1920x1080 HD.

Based on the provided list of codecs, which codec would minimize the storage requirement?

27. How does the Job Engine contribute to workload management?

How much on-disk space will be consumed for the data and protection overhead, excluding metadata?

31. 1.How does node architecture impact performance sizing in a PowerScale solution?

32. A customer is looking for a new storage solution to handle their growing storage requirements. The system should be able to cover storage needs for the next three years.

Which recommendation will meet the customer’s requirements?

33. What is the primary purpose of workflow analysis tools like tcpdump and Wireshark in PowerScale environments?

34. A customer has a data retention period of three years. They want a solution in which files cannot be deleted, changed, or modified.

Which Isilon SmartLock version should they implement?

35. A customer has eight X400 nodes with 24 GB RAM each, supporting 400 client connections today. They plan to add 400 more clients in the next few months and are considering adding an A-Series node to help with client connections.
