  A. 2
  B. 3
  C. 4
  D. 6
  C. 4

• Question 183:

  A. 0.5 ms
  B. 1 ms
  C. 2 ms
  D. 4 ms
  B. 1 ms

• Question 184:

  A major telecommunications operator is planning to consolidate multiple mid-tier storage arrays to a single Symmetrix VMAX solution. Their existing environment includes IBM AIX servers, HP-UX Servers and Windows 2003 Servers. When documenting the existing Server environment, which command can be used on the AIX Servers, to list the software modules installed?

  A. pkginfo
  B. lslpp
  C. swlist
  D. cfgmgr
  B. lslpp

• Question 185:

  You are designing a new VMAX array. The customer requires high performance for their random write- intensive application. Which RAID protection should you recommend?

  A. RAID-5
  B. RAID-6
  C. RAID-1
  D. RAID-S
  C. RAID-1

• Question 186:

  A customer has several internal organizational units with different requirements for their unique lines of business applications. Which approach provides the most predictable performance for each business unit on the array?

  A. Segregate the BCV/Clones/Pools across the front end, back end, engines, and disk to optimize each workload on its allocation of system elements.
  B. Evenly distribute the BCV/Clones/Pools across the front end, back end, engines, and disk to optimize use of all system resources.
  C. Evenly distribute the BCV/Clones/Pools across the front end, back end, engines, and disk, but only if the workloads are highly concurrent so that all system resources can be optimized.
  D. Segregate the BCV/Clones/Pools across the front end, back end, and engines, but only if the workloads demonstrate very low concurrence.
  A. Segregate the BCV/Clones/Pools across the front end, back end, engines, and disk to optimize each workload on its allocation of system elements.

• Question 187:

  A customer is planning a Tech Refresh. The proposed migration will make use of Open Replicator Hot Pull.

  Which Open Replicator Hot Pull feature allows the customer to minimize the possibility of data loss during the migration?

  A. Donor Update
  B. Symmetrix Differential Data Facility
  C. Protection Bitmap
  D. Symmetrix Track Table
  B. Symmetrix Differential Data Facility

• Question 188:

  A proposed SRDF/S solution was modeled with BCSD using host-based data.

  

  The BCSD model assumed two engine VMAX arrays with SRDF Fibre ports.

  

  The Compressed Throughput chart shows that the available throughput is greater than the peak throughput. The "Volume Exceptions" table lists ten devices. What should you recommend?

  A. Use three engine VMAX arrays
  B. Provide more bandwidth
  C. Turn off software compression on the remote adapters
  D. Change the application layout
  D. Change the application layout

• Question 189:

  A proposed SRDF/S solution was modeled with BCSD using host-based data. The BCSD model assumed two-engine VMAX arrays with SRDF Fibre ports. The RA Utilization chart shows a maximum utilization of 45%. The Volume Exceptions table lists five devices.

  What should be recommended?

  A. Change the application layout
  B. Add more remote adapters
  C. Use three-engine VMAX arrays
  D. Turn on software compression on the remote adapters
  A. Change the application layout

• Question 190:

  A customer wants to implement virtual provisioning on a new VMAX array and is concerned about efficient use of available storage and application performance.

  The VMAX environment will have file system, database and document repository hosts. The customer reports the system hosts append data to the file system, the database hosts use auto- extend and the document repository hosts have low performance and growth requirements. How should you recommend the host storage be provisioned on the VMAX array?

  A. File system storage on traditionally provisioned volumes; database and document repository storage on thin volumes.
  B. File system, database and document repository storage on thin volumes.
  C. File system and database storage on thin volumes; document repository storage on traditionally provisioned volumes.
  D. File system, database and document repository storage on traditionally provisioned volumes.
  A. File system storage on traditionally provisioned volumes; database and document repository storage on thin volumes.
