An existing TimeFinder customer migrated from a DMX-3 running Enginuity 5771 to a new VMAX array. They ask you to explain how the TimeFinder/Clone Copy on First Write (COFW) mechanism on the new VMAX array differs from their DMX-3 array.
What do you tell the customer?

• A.Both the VMAX and DMX-3 array use asynchronous COFW.
• B.The VMAX array uses synchronous COFW and the DMX-3 array uses asynchronous COFW.
• C.The VMAX array uses asynchronous COFW and the DMX-3 array uses synchronous COFW.
• D.Both the VMAX and DMX-3 arrays use synchronous COFW.

What is the EMC recommended network quality for SRDF/S over GigE?

• A.Less than 1% packet loss
• B.Less than 0.01% packet loss
• C.Less than 0.1% packet loss
• D.Less than 0.25% packet loss

Which TimeFinder feature allows you to use TimeFinder/Mirror commands to perform operations on RAID 6 protected BCVs?

• A.TimeFinder/Clone emulation mode
• B.Symmetrix Differential Data Facility
• C.TimeFinder/Clone compatibility mode
• D.TimeFinder/Mirror compatibility mode

You are designing an SRDF over GigE solution. What is a consideration to maximize TCP connection scaling?

• A.All GigE ports on the source array should be able to see all GigE ports on the target array.
• B.The MTU size must be hard set in the bin file on both the source and target arrays.
• C.The speed limit should be set on all GigE ports on both the source and target arrays.
• D.Jumbo frames must be enabled on the all GigE ports on both the source and target arrays.

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.SMF/TPF data for mainframe hosts IOSTAT data for AIX hosts
• B.CMF/TPF data for mainframe hosts SAR data for Linux hosts
• C.SMF/TPF for mainframe hosts SAR data for AIX hosts
• D.CMF/SMF data for mainframe hosts SAR data for HP-UX hosts
