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.

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.
The correct answer is B. Plan backend prerequisites, sizing, and service availability before installing self-hosted Instana. That aligns with the Domain 3: Installation 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 uses an overbroad rule instead of matching the design to the actual workload and risk. - Option C is incorrect because it skips the control or validation that makes backend installation 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. The correct answer is 'Plan backend prerequisites, sizing, and service availability before installing self-hosted Instana.'. The incorrect options — 'Start installation before meeting storage requirements', 'Ignore DNS and certificate planning', 'Use production data for installation testing only' — 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 3: Installation domain of the IBM Instana Observability certification.
