How should multiple program versions be managed with a programming device?

• A. The device can store and switch between multiple programs or configurations
• B. It cannot store more than one program
• C. It automatically updates firmware only
• D. It deletes old programs after each use

Answer: (A)

Managing multiple program versions on a programming device comes down to saving several programs or configurations on the device and choosing which one to run when needed. This capability lets you keep different revisions, test new changes without overwriting the original, and quickly switch between setups for different machines or processes. It also supports rollback if a new version doesn’t work as expected.

The other options don’t fit because a capable programming device is expected to store more than one program, not just update firmware automatically, and not delete old programs after each use. Those behaviors would make testing, version control, and recovery much more difficult.
