   • AReplication requires data reduction to be disabled on the source LUN.
   • BReplication will not work if data reduction is enabled.
   • CReplication sends only the reduced data blocks, reducing network bandwidth usage.
   • DReplication sends the full logical data, so data reduction does not affect bandwidth.
