A consultant is advising a customer that wants a scalable implementation. For IBM Certified Instana Observability Administrator, the topic is cloud service agents. What should the team do?

Here's the deal: think of cloud service agents like labeling the cables before you close the rack door. If you skip that discipline, troubleshooting gets ugly fast. 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 cloud service or serverless agents for managed services where host agents are not appropriate. 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 uses an overbroad rule instead of matching the design to the actual workload and risk. - Option B is incorrect because it skips the control or validation that makes cloud service agents reliable in production. - Option D is incorrect because it narrows the solution to one artifact or metric and misses the broader cloud service agents 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. The correct answer is 'Use cloud service or serverless agents for managed services where host agents are not appropriate.'. The incorrect options — 'Install host agents inside managed services you cannot access', 'Ignore cloud account permissions', 'Monitor cloud services only from billing reports' — 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.
