Which of the following is the LARGEST benefit from the LTO-4 specification regarding AES- GCM?

Data compression was a feature available in earlier LTO generations and, while improved, was not the specific enhancement related to AES-GCM in LTO-4.

Error detection and correction (EDC) are fundamental integrity features of tape technology, but they are distinct from the security features provided by AES-GCM encryption.

Tape cleaning is a maintenance process for tape drives and is unrelated to the LTO-4 specification's technical features, including AES-GCM.

The LTO-4 specification was groundbreaking for introducing hardware-based encryption, utilizing AES-GCM (Advanced Encryption Standard - Galois/Counter Mode), as a standard feature. This allowed data to be encrypted directly on the tape drive at full line speed, providing robust data security for sensitive information stored on tape without impacting performance or requiring separate software-based encryption solutions.
