• A. Data Courier will overwrite your MST build if the items/master file has not been locked down by your DC admin.
• B. Data Courier will always block the update.
• C. The update will be merged automatically.
• D. A new environment will be created.

Answer: (A)

In this situation, the items/master file acts as the source of truth for what goes into your MST build. If that file isn’t locked down by the DC admin, Data Courier will push the latest content from items/master directly to your MST build, effectively replacing your existing build with the new version. This happens because there are no guards to prevent automatic updates when no lock is in place, so the system applies the central content and overwrites local changes.

If a lock were in place, it would typically block or require explicit approval before any overwrite, preventing unintended changes. The other options describe behaviors that don’t align with the default when there’s no lock: blocking the update, merging automatically, or creating a new environment don’t reflect the overwrite behavior dictated by an unlocked source.
