   What is the primary purpose of Dell Unity Data Reduction?

   • ATo reduce the physical storage capacity required to store data by eliminating redundant data and compressing it
   • BTo encrypt data at rest to prevent unauthorized access to stored information
   • CTo provide data protection by creating multiple copies of data on different storage tiers
   • DTo increase the speed of data access by caching frequently used blocks in memory

   A Unity administrator has enabled Data Reduction on a pool and wants to verify that it is working correctly. In Unisphere, the administrator sees that the Data Reduction ratio is 1:1. What does this indicate?

   • AData Reduction is working correctly, and the pool has reached its maximum efficiency.
   • BData Reduction is not providing any savings, meaning the data is incompressible or the feature is not processing writes.
   • CData Reduction is compressing data at a 1:1 ratio, which is the standard compression level.
   • DData Reduction is deduplicating data at a 1:1 ratio, which is the standard deduplication level.

   How does Data Reduction interact with snapshots on Dell Unity?

   • ASnapshots are automatically deleted when Data Reduction is enabled
   • BSnapshots must be disabled when Data Reduction is enabled
   • CSnapshots are stored uncompressed to ensure data integrity
   • DSnapshots are not affected by Data Reduction and continue to work normally

   A media company is migrating its video editing storage to a Unity array. The editors work with large, uncompressed video files that are stored on a LUN and accessed over NFS. The files are modified frequently by multiple editors, and the company wants to reduce capacity usage. The storage administrator is considering enabling Data Reduction on the pool. What is the most important consideration before enabling it?

   • AData Reduction should be enabled only after the video files are archived, because it cannot process files that are already on the LUN.
   • BData Reduction will automatically compress the video files without any performance impact because it runs as a background process.
   • CData Reduction must be disabled for NFS LUNs because Unity only supports it on block LUNs.
   • DData Reduction will not provide significant savings on already-compressed video formats, and the write-heavy editing workload may suffer latency.
