Distribute an infrequently updated installation image physically to several devices with optical drives.
Removability and storage matter more than rewrite performance.
Which medium is a representative choice?
Optical media such as CD, DVD, or Blu-ray can be removed, stored, and used to distribute installation images. Capacity and rewrite support depend on the format.
Detailed explanation
Incorrect. A RAM disk is volatile and cannot serve as a physical distribution medium.
Correct. Optical discs are removable media for image distribution and storage.
Incorrect. An internal HDD is not the representative removable read-only distribution medium.
Incorrect. An internal SSD is fast local storage, not the assumed removable medium.
Try it yourself
An example you can run in a temporary verification environment.
printf '%s
' 'CD/DVD/BD: removable optical media'Expected result
光学メディアが取り外し可能な配布媒体であることを確認Key points
- Optical storage is removable
- Suitable for distribution and storage
- Formats differ in capacity and rewrite support
Notes
- Environment: ストレージ媒体の概念確認
- Prefer read-only inspection or a disposable system when testing hardware commands.
- Device visibility and module behavior depend on the host and virtualization environment.
Foundation review
Place the operation
A distribution medium must be removable and supported by the receiving hardware.
Check the side effect
Confirm the drive and media format before preparing the release.
