EMC Isilon Design Specialist Exam for Technology Architects : E20-554 exam

-- Exhibit -
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
-- Exhibit -
What steps would you recommend to the IT Director to allow for collaboration between the engineering company and the manufacturing company?

• A. Set up Access Zones on the Isilon cluster using Active Directory (AD) and NIS authentication.
  Create directories and apply user group permissions from AD and NIS for each collaboration
  team.
• B. Upload a collaboration user csv file into the cluster with usernames and passwords for the
  collaboration directory.
• C. Repoint the engineering users to the Active Directory controller
  Add the users to the appropriate Active Directory security group.
• D. Create a new pool for use by the collaboration users.
  Set up Access Zones on the Isilon cluster using AD and NIS authentication.

A customer is making a decision between Isilon and a competitor's offering. They currently have 100TB of usable capacity and are forecasting 100% growth per year for the next three years, which will require them to lease additional space in their co-located data center. The CFO finds ROI and TCO to be important decision criteria.
Which statement best emphasizes the value of Isilon for this customer?

• A. Isilon'sOneFS data protection policies offer substantially lower overhead than competitive RAID based NAS solutions.
• B. The competition cannot offer a scale-out NAS so as capacity is added to the array, performance may degrade.
• C. An IDC study found that Isilon requires 95% less down time hours per year compared to other competitors.
• D. Isilon'sOneFS allows administrators to manage much larger amounts of capacity than competitive offerings.

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

• A. Add Solid State Drives (SSDs) to the nodes
• B. Upgrade network interfaces on the nodes to 10 Gbps
• C. Add an A-Series Performance Accelerator node
• D. Upgrade RAM on the nodes

Refer to the exhibit.

Which tool was used to create this output and which line item counts the metadata read operations occurring in the file service?

• A. iostat and fsstat
• B. isi_netlogger and commit
• C. tcpdump and nfsstat
• D. nfsstat and getattr

We have been engaged by a research hospital to help upgrade their Isilon installation. They currently have 12 previous generation Isilon nodes with 200TB of capacity and run on a 1Gbps network. They currently have 6 Illumina Hi-Seq Sequencers and an HPC cluster to process data. They would like to expand Isilon to 2PB of active data and 1PB of archive data. They use a third party data and metadata management service (IRODs) to stage data for analysis. The Isilon cluster is mainly used for analysis work with the HPC cluster.

Before making any changes, the customer would like a graphical presentation of their existing array performance to present to management.What is the best tool to gather this information?

• A. tcpdump
• B. isi_netlogger
• C. netstat
• D. InsightIQ
