Which statement describes ACE environments regarding content and interchangeability?

• A. They contain different content and cannot be interchanged.
• B. They are only used for production.
• C. They must be rebuilt for each session.
• D. They contain the same content and are interchangeable.

Answer: (C)

ACE environments are designed as ephemeral, rebuilt for every session. This ensures a clean slate and reproducible conditions, so each learner starts from the same setup regardless of what happened in prior runs. If they were reused or interchangeable without rebuilding, residual changes could introduce variability and confusion. Rebuilding for each session is what preserves consistency and isolation across practice attempts.
