EMC E20-555 Online Questions & Answers

• Question 261:

  -- Exhibit -A European Sports TV network is considering Isilon for their Media Edit Storage for their editing workloads. They are also considering Isilon for near-line media archiving.

  The network receives XDCAM HD footage which is loaded onto their existing Transcoding Storage platform. New footage that needs to be edited will be transferred from their Transcoding Storage platform to the proposed Media Edit Storage

  platform at the rate of ten simultaneous XDCAM HD files via FTP. Edited files will be transferred back to the Transcoding Storage platform at the rate of ten simultaneous XDCAM HD files via FTP.

  The network currently has 15 Final Cut Pro edit stations, 15 Avid edit stations. Proxy software will be used to allow Isilon to act as the storage for the Final Cut Pro and Avid media. Three of those edit stations will be performing content

  compositing as needed.

  The network expects 70 hours of new content per week, and 50 hours of edited content per week. They intend to keep the new and edited content on the proposed Media Edit Storage as a performance tier for 30 days. They would like to

  retain all new and edited footage proposed Media Edit Storage as a near-line tier for two years.

  In addition to the current workloads, the network expects to implement a new Media Asset Management (MAM) solution and has requested the Isilon cluster be capable of supporting 120 MBps read and 120 MBps write to support the MAM

  requirements.

  -- Exhibit ?

  

  The customer wants to be able to put completed content into a non-editable folder. However, they want to give access to an administrator to delete content if required. What do you recommend to the customer?

  A. SmartLock using Enterprise mode
  B. SmartLock using Compliance mode

  D. SyncIQ with read-only mode
  A. SmartLock using Enterprise mode

• Question 262:

  A customer is evaluating Isilon and Pure FlashBlade solutions. Which protocol is available for both solutions?

  A. NFSv3
  B. SMBv3
  C. FTP
  D. HDFS
  C. FTP

• Question 263:

  A customer has an Isilon cluster that they want to simplify a Hadoop workflow. The workflow analyzes large amounts of log data written to storage using FTP and results are viewed by Microsoft Windows clients? How can this be achieved?

  A. FTP, SMB, and HDFS NameNode and DataNode protocol support on the same file system to enable each workflow step to access data from the same location avoiding data migration.
  B. SyncIQ to migrate the log data between an Isilon cluster and another Hadoop cluster, to retrieve results from the Hadoop cluster, and to store them in an SMB share.
  C. SmartConnect to direct clients to an external Hadoop NameNode and to SMB shares so data ingest, analytics, and results phases are transparently directed.
  D. FTP and SMB protocol support to provide log ingest and Windows clients; SmartPools will stub to HDFS helping to reduce the frequency of external data migration.
  A. FTP, SMB, and HDFS NameNode and DataNode protocol support on the same file system to enable each workflow step to access data from the same location avoiding data migration.

• Question 264:

  Using Isilon SnapshotIQ, how many snapshots can be created at the directory level?

  A. 8
  B. 96
  C. 256
  D. 1024
  D. 1024

• Question 265:

  What do you need to take into consideration when planning a job schedule?

  A. Any three other jobs can run at the same time and they can run in conjunction with restripe or mark job phases.
  B. Multiple restripe category job phases and one-mark category job phase can run at the same time.
  C. Up to three jobs can run at the same time. Multiple restripe or mark job phases can safely and securely run simultaneously without interfering with each other and without risk of data corruption.
  D. Up to three jobs can run at the same time. Multiple restripe or mark job phases cannot safely and securely run simultaneously without interfering with each other and without risk of data corruption.
  A. Any three other jobs can run at the same time and they can run in conjunction with restripe or mark job phases.

• Question 266:

  A. ID mapping stack
  B. Role-based access control
  C. Access Zone
  D. SmartLock
  A. ID mapping stack
