A team is preparing a production rollout and needs to avoid a design mistake. What is the best way to handle automated validation tests while staying aligned with the certification objectives?

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 A 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 A. Generate and run tests that compare transformed behavior against expected legacy behavior. That aligns with the Domain 7: Validate Transformed Code 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 B is incorrect because it narrows the solution to one artifact or metric and misses the broader automated validation tests requirement. - Option C is incorrect because it skips the control or validation that makes automated validation tests reliable in production. - Option D is incorrect because it sounds related, but it does not solve the automated validation tests 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.
