Which Media Types Allow for Permanent Data Storage?

A.

The correct answer is A. LTO WORM tape.

WORM stands for Write Once Read Many, and it is a type of technology that allows for permanent data storage, meaning that data once written on the media cannot be modified, deleted or overwritten. This is particularly important for regulatory compliance or legal reasons, as it ensures data integrity and prevents data tampering.

LTO (Linear Tape-Open) is a magnetic tape technology used for data backup and archiving. LTO WORM tapes have a special layer that is treated with a specific magnetic field during the writing process, which makes it impossible to erase or modify the data stored on the tape. This makes LTO WORM tapes ideal for long-term storage of critical data.

DVD-RW and CD-RW disks are recordable optical media that allow for multiple writes, meaning that data can be added, modified or deleted as many times as desired until the media reaches its capacity. DVD-RW disks are rewritable DVDs, and CD-RW disks are rewritable CDs.

LTO tapes, without the WORM capability, allow for multiple writes and overwrites, and are designed for data backup and recovery, rather than long-term permanent storage.

Therefore, A. LTO WORM tape is the only media type that allows for the ability to make data written to the media permanent.
