   What is a critical step in the planning phase of a cluster migration on a Dell midrange storage system?

   • ADeleting all snapshots to free up space for the migration
   • BDocumenting the current environment and defining the migration scope
   • CUpgrading the firmware on all switches before migration
   • DDisabling all replication sessions to avoid conflicts

   A company needs to create a point-in-time copy of a critical volume for backup purposes. They also want to use this copy to create a test environment. Which Dell midrange feature should they use?

   • ACreate a snapshot and use it directly as a test environment.
   • BCreate a snapshot, then create a thin clone from the snapshot.
   • CUse replication to create a point-in-time copy.
   • DCreate a thin clone directly from the production volume.

   A hospital is deploying a new electronic health record (EHR) system on a Dell midrange array. The EHR vendor states that the database files are already compressed at the application layer and that the data is highly random. The storage team wants to maximize capacity efficiency without impacting performance. Which data reduction approach should you recommend?

   • ADisable data reduction for this volume because the data is already compressed and random, so further reduction will be negligible and may impact performance.
   • BEnable only deduplication, since it works well on random data and avoids the CPU overhead of compression.
   • CEnable compression only, since it is always effective regardless of data type and will not affect performance.
   • DEnable both compression and deduplication on the volume, as they are complementary and will yield the highest reduction.

   What is a key management consideration when using thin clones on a Dell midrange array?

   • AThin clones consume the same amount of storage as the source volume
   • BThin clones cannot be used for write operations
   • CThin clones must be backed up independently to ensure data protection
   • DThin clones can be promoted to become independent volumes if needed

   A media company stores large video files on a Dell midrange array. The files are already compressed using a lossy codec. They want to enable data reduction to save space. What is the best practice?

   • AEnable deduplication only, since video files may have duplicate blocks.
   • BEnable both compression and deduplication to maximize savings.
   • CDisable data reduction because the files are already compressed and will not benefit from further reduction.
   • DEnable compression only, since video files are highly compressible.
