  A. Second write waits while first write is acknowledged.
  B. Third write waits while second write is acknowledged.
  C. 8 Concurrent writes are supported on a single device.
  D. 4 Concurrent writes are supported on a single device.

• Question 232:

  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. CMF/SMF data for mainframe hosts SAR data for HP-UX hosts

• Question 233:

  Refer to the exhibit.

  

  A customer has a legacy DMX-3 at Site 1, where a BCV-R1 copy is taken of the production volumes and then replicated to another DMX-3 at Site 2 via SRDF/A. The customer will replace the legacy DMX-3 arrays at both sites with new VMAX arrays.

  The customer wants to enable concurrent SRDF on the Site 1 SRDF source volumes, to maintain disaster restart protection between the legacy DMX-3 arrays and migrate the legacy DMX-3 at Site 1 to the new VMAX array. What should you advise the customer?

  A. Concurrent SRDF migration is not supported for this configuration.
  B. Enable concurrent SRDF using SRDF/A from the BCV-R1.
  C. Host level migration is the only migration option for this configuration.
  D. Enable concurrent SRDF using SRDF/S from the BCV-R1.
  A. Concurrent SRDF migration is not supported for this configuration.

• Question 234:

  Using Open replicator, when are the protection bitmap flags set to "1" for each track on the control device?

  A. When the session is created.
  B. When the session is terminated.
  C. When the session is activated.
  D. When the session is queried.
  A. When the session is created.

• Question 235:

  A. 25
  B. 50
  C. 300
  D. 100
