   A Metro Node administrator needs to move a virtual device to a new storage system. The administrator is concerned about the complexity of the operation and wants to ensure that rollback is possible if the migration fails. Which migration type provides the most straightforward rollback?

   • AExtent mobility
   • BBatch migration
   • CA manual copy with host path changes
   • DDevice mobility

   A company is consolidating two data centers into one. The Metro Node cluster spans both sites, and hundreds of virtual devices must be relocated to the surviving site. The migration must be coordinated to minimize disruption and be completed within a maintenance window. Which migration approach should the administrator choose?

   • ADevice mobility for each device individually, one at a time
   • BBatch migration to move all devices in a coordinated operation
   • CA manual script that copies data and updates host mappings
   • DExtent mobility to move individual extents from one site to another

   Which characteristic is unique to device mobility compared to extent mobility?

   • AIt is used exclusively for rebalancing capacity within a single pool
   • BIt requires hosts to be quiesced during the operation
   • CIt moves data at the sub-device granularity level
   • DIt relocates the complete virtual device to a different storage system

   How does extent mobility ensure data integrity during the migration process?

   • ABy copying the extent to the destination and then atomically switching the mapping
   • BBy moving the extent in small pieces and updating the host after each piece
   • CBy using a checksum to verify the data after the migration is complete
   • DBy requiring hosts to be quiesced before the migration begins

   A Metro Node administrator is planning a migration of a critical database. The database is actively being written to by hosts. The administrator is concerned about data consistency and wants to ensure that no writes are lost during the migration. Which migration type provides the strongest guarantee of data consistency?

   • AAll migration types provide the same data consistency guarantee through write-tracking
   • BBatch migration provides the strongest guarantee because it coordinates multiple moves
   • CExtent mobility provides the strongest guarantee because it moves less data
   • DDevice mobility provides the strongest guarantee because it moves the entire device
