A customer has several internal organizational units with very different requirements for their unique lines of business applications. Which approach provides the most optimal system performance?
A. Continue to distribute the BCV/Clones/Pools across the front end, back end, engines, and disk.
B. Segregate the BCV/Clones/Pools across the front end, back end, and engines to optimize each workload on its allocation of system elements.
C. Continue to distribute the BCV/Clones/Pools across the front end, back end, engines, and disk only if the workloads are highly concurrent.
D. Segregate the BCV/Clones/Pools across the front end, back end, and engines if the workloads are highly concurrent.

Which action is part of the analysis and design of a synchronous data protection solution for a Symmetrix VMAX implementation?
A. Use STP Navigator to examine the BTP data and determine if the data is valid for further analysis.
B. Use Performance Analyzer and EMC Control Center repository data to determine the peak data period and bandwidth required.
C. Use Symmetrix Performance Analyzer to determine the peak data requirement based on STP data collected from the source array for a 24 hour sample period.
D. Use Change Tracker to determine the bandwidth required from the DELTA data set for a given interval.
A customer plans to migrate mainframe and UNIX hosts from another vendor's array to an EMC Symmetrix. You are responsible for the design of the VMAX 20K solution that is to be replicated to a metropolitan bunker site. There is no tolerance for data loss.
Which input data sets do you need for a BCSD design of the replication solution?
A. CMF/SMF data for mainframe hosts SAR data for HP-UX hosts
B. SMF/TPF for mainframe hosts SAR data for AIX hosts
C. CMF/TPF data for mainframe hosts SAR data for Linux hosts
D. SMF/TPF data for mainframe hosts IOSTAT data for AIX hosts
A customer plans to migrate UNIX and Microsoft Windows clusters from another vendor's array to an EMC Symmetrix. You are responsible for the design of the VMAX 20K solution that is to be replicated to a metropolitan bunker site. There is no tolerance for data loss.
Which data is appropriate for the design of this solution?
A. IOSTAT data for Linux, Solaris, and AIX hosts ERFMON data for Windows hosts SAR for HP-UX hosts
B. IOSTAT for Linux and AIX hosts DISKPAR data for Windows hosts SAR data for HP-UX and Solaris hosts
C. IOSTAT data for Linux and AIX hosts PERFMON and DISKPAR data for Windows hosts
D. IOSTAT data for HP-UX and Linux hosts PERFMON data for Windows hosts SAR for AIX and Solaris hosts
Which statement is true relative to host-level performance measurement?
A. The host views each logical volume as a separate physical drive.
B. The host views each logical volume as shared storage.
C. The host can "see" the I/Os and response time globally.
D. The host views comprehensive response times.
