During a design review, an architect asks which choice best matches the IBM guidance. For IBM Certified watsonx Mainframe Modernization Architect, the topic is code rewrite process. What should the team do?

Here's the deal: think of code rewrite process like labeling the cables before you close the rack door. If you skip that discipline, troubleshooting gets ugly fast. In this scenario, answer B is the practical move because it keeps the implementation tied to the real IBM capability instead of chasing a shortcut. The other choices sound tempting, but they either skip governance, ignore operational reality, or solve the wrong problem.

The correct answer is B. Use the code rewrite workflow to generate Java modules and review them for functional equivalence. That aligns with the Domain 6: Transform COBOL Applications into Java Modules objective because it applies the feature or practice in the context where IBM expects a practitioner to use it. It also keeps the design reviewable, supportable, and realistic for a production environment.

Let's examine why the other options are incorrect: - Option A is incorrect because it uses an overbroad rule instead of matching the design to the actual workload and risk. - Option C is incorrect because it skips the control or validation that makes code rewrite process reliable in production. - Option D is incorrect because it sounds related, but it does not solve the code rewrite process requirement described in the scenario. For the exam, connect the feature to the operational outcome: the right answer is the one that preserves control, accuracy, and maintainability instead of relying on a brittle shortcut.
