Are module changes needed when updated?

• A. Yes, module changes are always required.
• B. No, no module changes are needed when updated.
• C. Sometimes module changes are required.
• D. Module changes are never allowed.

Answer: (B)

In modular design, updates are meant to be non-breaking, preserving the same interface that other parts of the system rely on. When you update a module, you typically create a new version that keeps the same inputs and outputs, so other modules can keep interacting with it without any changes. You only need to modify consuming modules if the update introduces a breaking change—for example, different required fields, altered data shapes, or changed behavior. So the best answer reflects that, under normal non-breaking updates, no module changes are needed.
