   A company is decommissioning an entire storage array. The Metro Node cluster has 50 virtual devices on this array that must be moved to a new array. The migration must be completed within a 4-hour maintenance window, and the administrator has limited staff available to monitor the operation. Which migration approach is most appropriate?

   • AExtent mobility for each device's extents
   • BBatch migration of all 50 devices
   • CA manual script that copies data and updates host mappings
   • DDevice mobility for each device, one at a time

   A Metro Node cluster is experiencing high CPU and network utilization. The administrator needs to move a small amount of data to rebalance a pool but wants to minimize the impact on cluster resources. Which migration type would consume the least CPU, memory, and network resources for this task?

   • AAll migration types consume the same resources for this task
   • BBatch migration, because it coordinates multiple moves efficiently
   • CExtent mobility, because it moves only the necessary data
   • DDevice mobility, because it moves the entire device in one operation

   In which scenario is device mobility most appropriate?

   • ARebalancing capacity between two pools on the same array
   • BMigrating hundreds of devices in one coordinated operation
   • CMoving a single hot extent to a faster storage tier
   • DReplacing an aging storage array with a new, higher-capacity model

   Which statement best describes the scope of an extent mobility operation?

   • AIt moves data between Metro Node clusters using asynchronous replication
   • BIt moves an entire virtual device, including all its extents, to a new storage system
   • CIt moves all devices in a consistency group simultaneously to a new array
   • DIt moves a subset of data extents from one storage pool to another within the same cluster
