   A storage administrator is planning a migration and is concerned about data integrity. The migration will move data while hosts are actively writing to it. Which migration type ensures data consistency by tracking writes during the move and applying them at the destination?

   • AOnly device mobility uses write-tracking to ensure consistency
   • BAll three migration types (extent, device, and batch) use write-tracking to ensure consistency
   • COnly batch migration uses write-tracking to ensure consistency
   • DOnly extent mobility uses write-tracking to ensure consistency
