During a design review, an architect asks which choice best matches the IBM guidance. What is the best way to handle use-case mapping while staying aligned with the certification objectives?

Here's the deal: think of use-case mapping like labeling the cables before you close the rack door. If you skip that discipline, troubleshooting gets ugly fast. In this scenario, answer D 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 D. Map Instana capabilities to concrete operational use cases such as root-cause analysis or SLO tracking. That aligns with the Domain 5: Planning 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 use-case mapping requirement described in the scenario. - Option B 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 sounds related, but it does not solve the use-case mapping 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. The correct answer is 'Map Instana capabilities to concrete operational use cases such as root-cause analysis or SLO tracking.'. The incorrect options — 'Buy observability before defining questions', 'Treat every team as having identical telemetry needs', 'Start with dashboard colors instead of operations goals' — are wrong because they do not align with IBM Instana's architecture or recommended practices for this scenario. Understanding this concept is essential for the Domain 5: Planning domain of the IBM Instana Observability certification.
