You are sizing an Isilon Gen 6 cluster for a small organization that is concerned about the availability of the journal during an extended power outage.
What is a consideration when sizing?

• A. Battery life within each node is a limiting factor
• B. Journal is written to nonvolatile storage if power is lost
• C. Journal is replicated to all nodes within a chassis
• D. Journal needs to be protected by an external UPS

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
  Redundant TaskTracker nodes
  Multi-protocol access to data
• D. Independent scaling of NameNodes
  Multi-protocol access to data
  Kerberos authentication

A 6 F800 node Isilon cluster has one subnet with two IP pools with LACP aggregated 10GigE interfaces from all the nodes in the 'Data-Zone' Access Zone. The 'NFS-Pool' with dynamic IP Allocation schema and 'SMBPool' with static IP Allocation schema are being used.
All the Linux clients are accessing Isilon exports using NFSv3 via the 'NFS_Pool'. All the Windows clients are accessing Isilon shares using SMBv3 via the 'SMB_Pool'.
While deploying Isilon, the customer reserves the whole network subnet for Isilon. The customer is facing performance issues with a new workload that is accessing the Isilon via Kerberized NFSv4.
What is recommended when creating a new IP pool for NFSv4 clients?

• A. Dynamic IP Allocation in the 'Data-Zone' access zone
• B. Static IP Allocation in the 'Data-Zone' access zone
• C. Dynamic IP Allocation in the 'System' access zone
• D. Static IP Allocation in the 'System' access zone

A customer requires a backup to tape of their Isilon cluster. They want advice on whether to implement a two-way NDMP solution or a three-way solution. The front-end network must be used to stream data to the backup solution.
Which cost-effective solution will meet their needs?

• A. Three-way without a Backup Accelerator
• B. Three-way including a Backup Accelerator
• C. Two-way including a Backup Accelerator
• D. Two-way without a Backup Accelerator

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?

• A. Direct all clients to use the Manufacturing DNS server and connect NFS mounts to the FQDN of the Isilon cluster.
• B. Mount an NFS share to a node on the Isilon cluster, being careful to equally distribute the load across nodes.
• C. Create an FQDN for the Isilon cluster in the LMHOSTS file for each engineering system.
• D. Utilize SMB2.1 protocol and mount to the Isilon cluster using the Name Server (NS) record IP.
