   After adding new drives to a Dell Unity dynamic pool, what does the system do to ensure data is evenly distributed?

   • AIt immediately moves all existing data to the new drives.
   • BIt leaves data on the original drives and only writes new data to the added drives.
   • CIt requires the administrator to manually redistribute data using a migration tool.
   • DIt automatically rebalances data across all drives in the pool.

   What is a performance impact of mixing drive sizes in a Dell Unity dynamic pool?

   • APerformance is unaffected because the pool treats all drives equally regardless of size.
   • BPerformance improves because the pool can use the faster drives for all read operations.
   • CPerformance may degrade because the pool must use the slower drive as the baseline for all operations.
   • DPerformance improves because larger drives have higher rotational speeds.

   During a drive rebuild in a Dell Unity dynamic pool, what is the impact on pool performance?

   • APerformance improves because the rebuild process optimizes data placement.
   • BPerformance may degrade because the rebuild process consumes I/O resources and competes with normal operations.
   • CPerformance is temporarily suspended until the rebuild is complete.
   • DPerformance is unaffected because the rebuild uses dedicated hardware that does not interfere with normal I/O.

   In a Dell Unity dynamic pool, a drive fails. What happens to the data that was stored on that drive?

   • AThe data remains inaccessible until the failed drive is replaced and the system restores it from backup.
   • BThe data is automatically rebuilt onto spare capacity within the pool.
   • CThe data is lost permanently because there is no redundancy in a dynamic pool.
   • DThe data is copied to a designated hot spare drive that must be manually assigned.

   A financial firm has a Unity XT dynamic pool with a mix of 10 TB and 14 TB drives. One of the 10 TB drives fails. The pool has no dedicated hot spare. What happens to the data on the failed drive?

   • AThe system automatically replaces the failed drive with a new one from inventory.
   • BThe data is lost because there is no hot spare.
   • CThe data is rebuilt onto spare capacity distributed across the remaining drives in the pool.
   • DThe pool becomes read-only until the drive is replaced.
