An administrator is troubleshooting a pilot deployment and wants the most appropriate next step. The team is focused on application discovery. Which recommendation is most appropriate?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Here's the deal: think of application discovery like labeling the cables before you close the rack door. If you skip that discipline, troubleshooting gets ugly fast. 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 discovery to understand dependencies, data flows, transactions, and candidate modernization boundaries.. This aligns with the IBM exam objective for this domain, as it represents the approach that preserves operational control, accuracy, and maintainability.
If you skip that discipline, troubleshooting gets ugly fast. 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 discovery to understand dependencies, data flows, transactions, and candidate modernization boundaries. That aligns with the Domain 3: Discover and Explain Existing Mainframe Applications 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 sounds related, but it does not solve the application discovery requirement described in the scenario. - Option C is incorrect because it relies on an assumption rather than verifying the architecture, permissions, or operational behavior. - 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 discovery to understand dependencies, data flows, transactions, and candidate modernization boundaries.. Option B — Incorrect: Start rewriting before dependency analysis. Option C — Incorrect: Assume file names reveal business capability. Option D — Incorrect: Modernize only the smallest programs first.
