Which statement describes the T10 SCSI UNMAP process? *

2 points

Bytes that are in memory of the host system are identified as duplicates and only the non-duplicate bytes are sent to the storage device

Blocks of storage are identified in the host file system as deleted and sent to the storage device with an UNMAP request to remove the blocks as they are now free

Blocks of storage are deleted from the host and then removed from memory using the ~unmap~ command

Files are deleted from the host and then UNMAP is used to remove the files from the host allocation table but not from the storage device
