  5. The performance of a response critical application generating a majority of 4 KB IOs has progressively deteriorated on a new modular storage system as unplanned development and general file serving workloads have been added. The system administrator is convinced that this is due to falling cache hit rates.

  A.Place the response critical application in its own cache partition.
  B.Upgrade the cache from 8 GB to 16 GB.
  C.Reduce the application cache partition segment size from 16 KB to 8 KB.

  E.Move the development and general file server workloads to lower performance tier RAID Groups.
  Answer: ABC

  6. Solaris IOSTAT shows that response times are degrading for a number of LUNs and that these LUNs are 100% busy. The active queue values are in a range up to, but not exceeding 8, and the wait queue values are in the range from 0 to 5 when the active queue is 7 or 8.
  Which condition is implied by these values?
  A.These are normal values for busy LUNs with a LUN queue depth of 8.
  B.There are no more Tags available on this storage port due to heavy IO load.
  C.There are no more Tags available for these LUNs at the port due to heavy IO load.
  D.The HBA LUN queue depth is set incorrectly.
  Answer: A

  A.load_balance_none
  B.load_balance_rr
  C.load_balance_lba
  D.load_balance_fixed
  Answer: A

  8. Which three actions will help to reduce the level of Write Pending data in cache during periods of intense random update processing? (Choose three.)

  B.Migrate from RAID5 to RAID1.
  C.Spread the load across more RAID Groups.
  D.Spread the load across more ports.
  E.Spread the load across more LUNs.

  A.DRR RAID processors
  B.DKP/DKA processors
  C.back-end loops
  D.dedicated data paths from the BED to the cache switch
  Answer: A

  10. Which level of Write Pending is normal for a busy OLTP Universal Storage Platform (USP) system adequately managing the destaging of writes?
  A.0% to 20%
  B.20% to 30%
  C.30% to 40%
  D.40% to 50%
  Answer: B

  11. Performance monitor data indicates that CHP utilization may be causing a bottleneck in a Universal Storage Platform (USP) series system during periods of intense processing.
  Which two actions should be considered to increase IOPS during the bottleneck periods? (Choose two.)
  A.Configure the paths using high-speed mode.
  B.Spread the load across more CHP processors and paths.
  C.Spread the load across more RAID Groups.
  D.Spread the load across more LUNs.
  Answer: AB

  12. The performance of an audio streaming modular storage system has deteriorated as more streams have been added. Audio streaming is the only workload on the array and the store consists of many thousands of separate audio files. Cache hit rates drop quickly as several streams are started.
  Which two will improve the prefetch for the audio but prevent prefetch taking place for the directory accesses? (Choose two.)
  A.multi-stream mode
  B.count of sequential judgment
  C.high speed write mode
  D.disable verify after write
  Answer: AB

  13. Click the Exhibit button.
  Which three conditions are likely causes for the write pending rates illustrated in the exhibit? (Choose three.)
  A.insufficient cache
  B.loss of redundancy in write cache
  C.heavy random writes to RAID5
  D.heavy random writes to SATA drives
  E.failure to distribute workload among sufficient array groups
  Answer: CDE
