Who is responsible for configuring the training environment for their application(s)?

• A. Principal trainer
• B. TST
• C. ODBA
• D. Environment Copy Utility

Answer: (A)

The person who configures the training environment is the principal trainer because they own the training plan and know exactly what software, data, and configurations the learners will need. They set up and verify the tools, versions, dependencies, and datasets so the environment matches how the application will be used in practice, making the exercises reproducible and reliable for all sessions. Other roles might support or manage different aspects, but the responsibility for shaping the training sandbox to fit the application rests with the principal trainer.
