Your customer's initial use case was Home Directories. They implemented the cluster with four 1Gbps ports and LACP. They are planning to expand their cluster to support their core file services. They plan to upgrade their network infrastructure to 10 GbE to facilitate this.
What are two design impacts this change will have?

1. A. Maximum performance is obtained by only using a single 10GbE interface per node.LACP and multiple links may be used to increase redundancy, but will not provide more overall performance to the system
2. B. LACP and multiple links may be used to increase redundancy, but will not provide more overall performance to the system.FCoE should be considered for the External Network Ports on the nodes.
3. C. Dual 10GbE ports on each node will enable throughput of 20Gbps.Only connect half of the nodes to the network.
4. D. Maximum performance is obtained by only using a single 10GbE interface per node.Isilon can support up to 400MB/s per node

Correct Answer: A

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.

Which configuration changes would you recommend for the Engineering users?

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

Correct Answer: A

While configuring Isilon SmartConnect, a customer determined that their workload primarily consists of long-lived NFS and SMB connections. Which load-balancing policy will provide the most efficient client distribution?

1. A. Random Selection
2. B. CPU Utilization
3. C. Network Throughput
4. D. Connection Count

Correct Answer: C

A customer plans to deploy N+2d:1n protection on a 5-node Isilon cluster. How much capacity will be used to store a 320 KiB file?

1. A. 512 KiB
2. B. 448 KiB
3. C. 576 KiB
4. D. 640 KiB

Correct Answer: C

You are designing an Isilon 5-node cluster configuration for a customer who wants to store user home
directories on the new cluster. Each user has 100 small files of 4KB each, 100 medium sized files of 80KB each, and 100 larger files of 512KB each. How much space is occupied by the medium sized files data blocks on an N+1n cluster?

1. A. 9,600KB
2. B. 15,360KB
3. C. 16,000KB
4. D. 25,600KB

Correct Answer: A
