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. Plan SaaS or self-hosted architecture around scale, retention, security, and network reachability. 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 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 skips the control or validation that makes architecture planning 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 SaaS or self-hosted architecture around scale, retention, security, and network reachability.'. The incorrect options — 'Choose architecture after installing agents', 'Ignore retention until storage is full', 'Use one test host to size all production workloads' — 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.
