   What is the primary definition of a batch migration in a Dell Metro Node environment?

   • AMoving an entire virtual device to a new storage array for hardware refresh
   • BMoving a single data extent from one pool to another to fix a performance hotspot
   • CCopying data from a Metro Node cluster to a tape backup system for archival purposes
   • DCoordinated movement of multiple devices or extents in a single operation to minimize disruption

   A storage administrator must migrate a large number of extents from one pool to another to rebalance capacity. The administrator is considering two approaches: extent mobility for each extent individually, or a batch migration. Which statement correctly compares the operational complexity of these two approaches?

   • ABatch migration is less operationally complex because it coordinates the moves in a single operation
   • BExtent mobility is less operationally complex because it moves less data
   • CBatch migration is more operationally complex because it involves more data
   • DBoth approaches have the same operational complexity

   What is the typical impact of device mobility on host access?

   • AIt causes a complete outage for the duration of the migration
   • BIt only affects hosts that are actively writing to the device
   • CIt maintains host access to the virtual device throughout the process
   • DIt requires hosts to be rezoned and remapped to the new storage
