   A Unity array hosts a file share with large, uncompressed video files. The storage team wants to reduce capacity usage. The files are unique, so deduplication will not help. What should they do?

   • AEnable deduplication on the file share to eliminate duplicate blocks.
   • BEnable both deduplication and compression to maximize savings.
   • CDo not enable data reduction because video files are not compressible.
   • DEnable compression on the file share to reduce the size of the video files.

   What is the primary purpose of data reduction on a Dell Unity storage system?

   • ATo increase the number of snapshots that can be taken
   • BTo reduce the physical storage capacity required to store data
   • CTo improve the speed of data access for frequently used files
   • DTo ensure data is protected against hardware failures

   How does data reduction interact with snapshots on a Dell Unity system?

   • ASnapshots are stored in a separate pool without data reduction
   • BSnapshots are not affected by data reduction and always use full copies
   • CData reduction must be disabled before taking a snapshot
   • DSnapshots of data-reduced LUNs use less physical space because they reference reduced data

   A financial services firm runs a high-transaction database on a Unity array. The database has a high write rate, and the storage team is considering enabling data reduction to save capacity. They are concerned about the impact on write latency. Which approach should they take?

   • AEnable inline data reduction to reduce capacity without affecting write latency.
   • BDisable data reduction entirely to guarantee no impact on write latency.
   • CEnable compression only, because it has less impact on write latency than deduplication.
   • DEnable post-process data reduction to minimize the impact on write latency.

   How does deduplication identify redundant data blocks in a Dell Unity system?

   • ABy checking the file extension and type
   • BBy comparing file names and sizes
   • CBy computing and comparing hash values of data blocks
   • DBy analyzing access patterns to find similar data
