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

Here's the deal: application blueprint is not just a checkbox; it is the difference between a clean handoff and a late-night recovery call. In this scenario, answer C 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 C. Use the application blueprint to reason about structure, relationships, and modernization candidates. 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 sounds related, but it does not solve the application blueprint requirement described in the scenario. - Option B is incorrect because it skips the control or validation that makes application blueprint reliable in production. - Option D is incorrect because it narrows the solution to one artifact or metric and misses the broader application blueprint requirement. 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.
