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. Considering the customer's requirements, which is the best node type for the Isilon cluster? A. NL400 with 48 GB RAM and no SSDs per node. B. X400 with 96 GB of RAM and no SSDs per node. C. X400 with 24 GB RAM and 1.6 TB of SSD per node. D. X200 with 24 GB of RAM and 1.2 TB of SSD per node. Answer: B 22.Your customer has an Isilon Gen 6 cluster with eight H400 nodes.

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