Which of the following tape drive features protects data from unauthorized use?

Multi-streaming allows a single tape drive to receive data from multiple hosts or applications simultaneously, improving performance, not protecting data from unauthorized use.

Multiplexing combines multiple data streams into a single stream to be written to tape, which can improve efficiency but does not provide data protection from unauthorized use.

Compression reduces the size of data to save storage space and increase write/read speeds, but it does not protect the data from unauthorized access.

Encryption is the tape drive feature that protects data from unauthorized use by encoding the data, making it unreadable without the correct decryption key. This process ensures confidentiality and is a critical security measure for data stored on tape media, especially for archival or offsite backups.
