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
The CIO approaches you with a new requirement. They would like to reuse the tape library that was previously used for archiving to now be used to back up some of their data.
What do you recommend to the Director of IT as the best architecture to achieve this goal?

• A. Connect the Tape Library via Fibre Channel to the Isilon cluster and use a third party backup software to initiate an NDMP backup to an accelerator.
• B. Implement a Backup Accelerator and use the internal backup software within the Isilon cluster to move data to the tape library.
• C. Use a Backup Accelerator with SynclQ to push the data to the tape library via the Fibre Channel ports on the accelerator.
• D. Use a third party backup software and have the Isilon cluster convert the data to LTFS so it can be stored to the tape library.

A customer is using Hadoop with direct-attached storage. They are concerned about the cost to build and maintain this infrastructure.
What are the benefits of switching to Hadoop with Isilon OneFS?

• A. Independent scaling of compute and storage Multi-protocol access to data ACL-based permissions
• B. Independent scaling of compute and storage Independent NameNodes Kerberos authentication
• C. Independent scaling of NameNodes Multi-protocol access to data Kerberos authentication
• D. Independent scaling of NameNodes Redundant TaskTracker nodes Multi-protocol access to data

Your customer, a metropolitan newspaper, uses Secure FTP (SFTP) to upload stories and images for print workflows. Their existing competitor's storage array is going out of support, and future SFTP support is being dropped.
This SFTP workflow is not covered in their disaster recovery plan.
Which qualifying questions would uncover this requirement early?

• A. What protocols (SFTP, SMB, NFS) are in use? What does your infrastructure look like? How do you manage file systems?
• B. What is your infrastructure? What applications access the storage? What protocol versions are in use?
• C. What is your network infrastructure? How many storage fabrics do you have? What is your disaster recovery plan?
• D. How much capacity is required? What applications access the storage? What risks exist in your infrastructure?

A customer is interested in configuring a snapshot on /ifs/clustername/ because this directory has all of their data and they can restore data to this path whenever needed.
What should you tell the customer?

• A. Use snapshots created by SyncIQ policies to restore the data
• B. Take a snapshot of /ifs to reduce management overhead
• C. Schedule snapshots for critical data paths and set retention period based on business requirements
• D. Configuring snapshots will occupy additional space equal to the data size on the cluster

An architect is designing a solution for a new customer. The customer is going to use the cluster to store a large number of files that will be accessed by many users.
What IO optimization should be used and what kind of prefetching will take place?

• A. Concurrency, aggressive prefetching
• B. Random, aggressive prefetching
• C. Concurrency, no prefetching
• D. Concurrency, moderate prefetching
