• Question 72:

  In a TS7740 two-way grid Cluster 0 is the production site and Cluster I is the remote DR site. The scratch volume category for the production site is 0012 and DR site's scratch volume category is 0022. Before a DR test is started, several DR system updates must be in place to protect the production scratch volumes from being allocated during the test. Assuming Selective Write Protect is enabled, which of the following is one step that must be taken?

  A. Update the DR TCDB volume entries to change the production volumes from 0012 to 0022
  B. Update the DR system's DEVSUPxx parmlib member to use a unique scratch volume category
  C. Disconnect the grid link connections to ensure production volumes are not updated in the remote cluster during the DR test
  D. Run the Return To Scratch process from the DR system to ensure the production and DR system volumes are in sync and protected during a DR test
  B. Update the DR system's DEVSUPxx parmlib member to use a unique scratch volume category

• Question 73:

  A. 324 frames do not provide the option for adding tape drives
  B. 324 frames cannot be placed at either end of the tape library
  C. 324 frames provide 2.5 times more cartridge slots compared to D frames
