Which of the following media types allows for the ability to make data written to the media permanent?

LTO WORM tape uses a Write Once Read Many format, meaning sectors are permanently locked after the initial write operation. Unlike standard LTO tape, the WORM variant applies a cryptographic or physical mechanism that prevents overwriting, making it ideal for compliance and archival use cases where data permanence is required.

DVD-RW is a rewritable optical format that allows data to be erased and re-recorded multiple times, so it does not make data permanent.

CD-RW is also a rewritable optical format that supports multiple erase and write cycles, meaning data written to it is not permanent.

Standard LTO tape is a read/write medium that allows data to be overwritten and erased across its full lifecycle, offering no WORM protection.
