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 explanation. What should the team do?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Here's the deal: you would not ship a production change with no owner and no rollback plan. The same common sense applies here. 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.

Full Explanation
The correct answer is B: Use code explanation to help teams understand COBOL logic while validating results with SMEs.. This aligns with the IBM exam objective for this domain, as it represents the approach that preserves operational control, accuracy, and maintainability.

The correct answer is B. Use code explanation to help teams understand COBOL logic while validating results with SMEs. That aligns with the Domain 3: Discover and Explain Existing Mainframe Applications 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 narrows the solution to one artifact or metric and misses the broader code explanation requirement. - Option C is incorrect because it skips the control or validation that makes code explanation reliable in production. - Option D is incorrect because it sounds related, but it does not solve the code explanation 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.
Option A — Incorrect: Treat generated explanation as the only authority. Option B — Correct: Use code explanation to help teams understand COBOL logic while validating results with SMEs.. Option C — Incorrect: Avoid SME review of critical logic. Option D — Incorrect: Use explanation output as deployable code.
