• Question 31:

  By default, how much storage is allocated when a thin device is bound to a pool?

  A. 1 extent
  B. 1 track
  C. 12 extents
  D. 64 tracks
  A. 1 extent

• Question 32:

  Exhibit:

  

  You have used BCSD to model an SRDF/A solution and have an SRDF/A risk analysis, as shown in the exhibit. What should be your recommendation?

  A. Ensure that the RDF devices use the same RAID and drive configuration. Provide more remote adapters.
  B. Provide more bandwidth. Upgrade both arrays to Symmetrix VMAX.
  C. Ensure that the RDF devices use the same RAID and drive configuration. Provide adequate bandwidth.
  D. Provide more bandwidth and more remote adapters. Ensure that the local and remote arrays run the same Enginuity level.
  A. Ensure that the RDF devices use the same RAID and drive configuration. Provide more remote adapters.

• Question 33:

  A customer wants to protect production data using local and remote replication on a pair of VMAX arrays located 500 km apart. Both VMAX arrays are fully configured with virtually provisioned thin volumes.

  The customer has a Recovery Point Objective (RPO) of thirty minutes and wants to replicate the production volumes to the remote array while maintaining a separate backup copy on the local array. Which replication options do you recommend they implement?

  A. TimeFinder/Clone and SRDF/A.
  B. TimeFinder/Clone and SRDF/S.
  C. TimeFinder/Mirror and SRDF/A.
  D. TimeFinder/Snap and SRDF/S.
  A. TimeFinder/Clone and SRDF/A.

• Question 34:

  When using Clone Emulation, which TimeFinder/Clone command represents the symmir establish command?

  A. symclone create -precopy -differential
  B. symclone create -precopy -incremental
  C. symclone establish -copy
  D. symclone activate -copy
  A. symclone create -precopy -differential

• Question 35:

  Changes were made to a TimeFinder Clone after activation. The changes need to be propagated back to the source. Which method should be used?

  A. Incremental restore
  B. Incremental establish
  C. Full restore
  D. Full establish
  A. Incremental restore

• Question 36:

  When performing a consistent mode change from SRDF/A to SRDF/S, how many cycles does this process take?

  A. After two cycle switches
  B. After one cycle switch
  C. Immediately
  D. After the cycle time expires
  A. After two cycle switches

• Question 37:

  A storage administrator receives a warning message that one of the thin pools in the Symmetrix is low on storage space. The pool contains a large number of thin devices that have been fully preallocated but have small amounts of used space. What is the least disruptive and most cost effective way to make more thin pool space available?

  A. Run zero space reclamation on the thin devices
  B. Add more data devices to the thin pool
  C. Unbind the underutilized thin devices from the pool
  D. Rebalance the pool
  A. Run zero space reclamation on the thin devices

• Question 38:

  When should customers implement SRDF/S solutions?

  A. When they cannot afford to lose any data
  B. When IO response time is very critical to applications.
  C. When high bandwidth is required by an application.
  D. When an array has and abundance of cache buffer.
  A. When they cannot afford to lose any data

• Question 39:

  A Symmetrix VMAX hosts four applications. Each application is assigned a named dynamic cache partition. Two of the partitions are static and two are flexible. The write pending limit for each partition is set to 60%. What will happen if an application running in a static partition reaches the write pending limit set for that partition?

  A. Cache will be borrowed from a flexible partition
  B. Cache will be borrowed from the default partition
  C. Host write activity to that partition will be throttled
  D. The write pending limit of the partition will be raised until it reaches 80%
  C. Host write activity to that partition will be throttled

• Question 40:

  A customer has implemented an Oracle application on a Symmetrix VMAX with a mix of Enterprise Flash Drives (EFD) and FC 15K drives. EFD are configured in RAID 5, and FC 15K drives are configured both in RAID 5 and RAID 1. In terms of IOPS activity, reads are predominant over writes. The customer decided to place a portion of the database in each tier.

  Which Oracle database object(s) is suitable for placing on the FC 15K RAID 1 drives?

  A. Redo log files
  B. Data files
  C. Index files
  D. Temp file
  A. Redo log files
