A consultant is advising a customer that wants a scalable implementation. Which approach best demonstrates functional requirements in a IBM Certified watsonx Mainframe Modernization Architect environment?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Here's the deal: this is where a demo turns into an operation. The design has to survive real users, real failures, and real audits. 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.

Full Explanation
The correct answer is A: Use functional and non-functional requirements to guide architecture, sizing, and integration choices.. This aligns with the IBM exam objective for this domain, as it represents the approach that preserves operational control, accuracy, and maintainability.
The design has to survive real users, real failures, and real audits. 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. Use functional and non-functional requirements to guide architecture, sizing, and integration choices. That aligns with the Domain 2: Architecture & Components 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 functional requirements requirement. - Option C is incorrect because it skips the control or validation that makes functional requirements reliable in production. - Option D is incorrect because it uses an overbroad rule instead of matching the design to the actual workload and risk. 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 — Correct: Use functional and non-functional requirements to guide architecture, sizing, and integration choices.. Option B — Incorrect: Choose deployment based only on tool defaults. Option C — Incorrect: Ignore availability and latency requirements. Option D — Incorrect: Treat every application as stateless.
