   A Unity administrator has a LUN with data reduction enabled and a snapshot of that LUN. The snapshot is taken to protect against accidental deletion. How does data reduction affect the snapshot?

   • AThe snapshot requires twice the capacity because it duplicates the reduced data.
   • BThe snapshot stores a full copy of the LUN, so data reduction does not apply.
   • CThe snapshot uses the same reduced data blocks as the production LUN, so it consumes minimal additional capacity.
   • DThe snapshot disables data reduction for the LUN to ensure data integrity.
