During an MST upgrade, which statement about the training build and configurations is true?

• A. The upgrade requires a full rebuild of the training environment.
• B. The upgrade only updates the UI with no changes to features.
• C. During an MST upgrade, the code in the environment is upgraded, enabling new features and potentially changing the look and feel; your configurations and training build remain afterwards and do not need to be rebuilt.
• D. Upgrades erase existing training content.

Answer: (C)

Upgrading updates the code that runs in the training environment, bringing in new features, fixes, and possibly changes to the user interface. The important point is that your existing training build and configurations stay in place after the upgrade, so you don’t need to rebuild them from scratch. This continuity allows you to continue your training work with the new capabilities without starting over. The interface may look different as features evolve, but the underlying training content and setup remain intact.
