• Question 121:

  The NAR file on a source CLARiiON array is 12 hours of 300 second intervals. You require a minimum of 30 intervals of complete data. How many 30-minute trace files will need to be collected from the CLARiiON for a Tier Advisor analysis?

  A. 4
  B. 5
  C. 6
  D. 7

  B. During writes to protected tracks on the virtual device
  C. During all writes to the source device
  D. During all writes to the virtual device
  A. During writes to protected tracks on the source device

• Question 123:

  You have been working with a customer on a new SRDF/A design and need to validate the configuration using Symmetrix data. Which tool do you use?

  A. SymmMerge
  B. Tier Advisor
  C. E-lab Advisor
  D. Analyzer Helper
  A. SymmMerge

• Question 124:

  An SRDF/S implementation is being designed. The application is doing 6,000 4 KB IOPS with 30% writes and uses multiple volumes. Assume that the RA performance limits are 3,800 4 KB IOPS for a Fibre RF adapter. How many RFs are recommended?

  A. 1
  B. 2
  C. 4
  D. 6
  B. 2

• Question 125:

  A customer is planning an Oracle 11g implementation. You have been asked to design the Oracle storage architecture. You recommend placing redo log files on separate drives from other Oracle files. Your customer wants an explanation of this architecture choice.

  What best describes the reason for this EMC recommendation?

  A. Redo logs' write performance can affect the performance of the entire database
  B. Separation ensures that disk failure will not result in losing the entire database
  C. Redo logs on the same drives as the Oracle data files is not supported
  D. Redo logs' read performance can affect the performance of the entire database
  A. Redo logs' write performance can affect the performance of the entire database

• Question 126:

  You are designing tiered storage for a new 2-engine VMAX. What is the minimum number of Flash drives you should recommend not including hot spares?

  A. 8
  B. 32
  C. 24
  D. 16
  D. 16

• Question 127:

  A customer needs to have copies of their production database accessible to backup and recovery team. The production data resides on a VMAX and backup and recovery resides on a CLARiiON. Which tool is appropriate for meeting their goal?

  A. TimeFinder
  B. SRDF
  C. Open Replicator
  D. MirrorView
  C. Open Replicator

• Question 128:

  You are designing a new VMAX implementation. All applications will share physical drives and participate in SRDF/S replication.

  The customer has two high I/O applications used for OLTP and a several low I/O applications used for testing. The customer wants to ensure the high I/O applications take precedence over the low I/O applications on the VMAX array. What do you recommend?

  A. Implement Symmetrix Priority Controls.
  B. Configure striped metavolumes.
  C. Implement SRDF Consistency Groups.
  D. Configure concatenated metavolumes.
  A. Implement Symmetrix Priority Controls.

• Question 129:

  Your customer is using Replication Manager to make local TimeFinder/Clone backups of their Microsoft Exchange 2010 environment. The customer reconfigured the Exchange environment to place the logs on the L:\ drive and mount the database on L:\SG1DB1. They updated the associated Replication Manager replica job to reflect the change. The customer reports that the mount of the database to the backup server now fails.

  What do you advise the customer?

  A. Nested mount points are not supported with Replication Manager.
  B. A separate application set must be configured for the database.
  C. Additional clone targets need to be added to the storage pool.
  D. The database replica must be part of the same replica job as the logs.
  A. Nested mount points are not supported with Replication Manager.

• Question 130:

  A customer wants data from a source to be copied to its TimeFinder/Clone target as soon as the session is created. Which option needs to be used when creating the TimeFinder/Clone session?

  A. precopy
  B. copy
  C. establish
  D. differential
  A. precopy
