HP0-J73 · Question #120
Which tape technology prevents data from being overwritten and is used for long-term archiving?
The correct answer is D. Write-once read-many (WORM). WORM media physically or logically prevents overwriting after initial write, making it the standard technology for compliance and long-term archival storage.

Why each option
WORM media physically or logically prevents overwriting after initial write, making it the standard technology for compliance and long-term archival storage.
AIT (Advanced Intelligent Tape) is a rewritable Sony tape format optimized for performance and capacity, not for preventing overwrites.
DDS (Digital Data Storage) is a rewritable DAT-based tape format used for backup; it offers no inherent overwrite protection.
OLT-P (Optical Linear Tape - Passive) is a high-capacity optical tape format but is not specifically designed as a WORM technology for general archiving use.
Write-once read-many (WORM) technology ensures data is permanently recorded and cannot be altered or deleted after it is written. This immutability characteristic is mandated for regulatory compliance (such as SEC 17a-4) and long-term archiving, distinguishing it from all other rewritable tape formats.
