IBM Certified watsonx Mainframe Modernization Architect v1 - Associate · 43 questions

• What is the primary purpose of IBM watsonx Code Assistant for Z (wca4z)?
• In the IBM Z Modernization lifecycle, which phase sequence is correct?
• What role does generative AI play in the Transform phase of IBM watsonx Code Assistant for Z?
• IBM watsonx Code Assistant for Z transforms COBOL business logic into which target language?
• What is the primary output of the Discover phase in IBM Z Modernization?
• Which IBM Z ecosystem component does wca4z integrate with to collect application metadata before transformation?
• IBM watsonx Code Assistant for Z is accessed by developers through which primary interface?
• What distinguishes the large language model used by IBM watsonx Code Assistant for Z from a general-purpose coding assistant?
• Which outcome best describes the primary business value of transforming COBOL to Java using wca4z?
• Why does IBM recommend a phased migration approach with wca4z rather than a big-bang replacement?
• Within the IBM watsonx platform, which description best positions IBM watsonx Code Assistant for Z?
• How does wca4z support a strategy where only selected COBOL programs are transformed while the rest remain in COBOL?
• What business problem does identifying dead code in the Discover phase primarily address?
• The Explain feature in wca4z generates natural language descriptions of COBOL programs primarily to benefit which audience?
• How does wca4z differ from traditional COBOL-to-Java conversion tools that have existed since the early 2000s?
• Which role is primarily responsible for reviewing and approving wca4z-generated Java code before production promotion?
• IBM watsonx Code Assistant for Z is designed to process programs written in which COBOL dialect?
• What does IBM recommend to maintain governance over AI-generated Java code produced by wca4z?
• What is watsonx Code Assistant for Z primarily meant to accelerate?
• No criteria have been documented for where each transformed workload should be deployed, and the plan is due for sign-off this week. What should drive that decision?
• Which combination of skills does a successful COBOL-to-Java modernization project actually require?
• Which principle should guide how a modernised mainframe application is decomposed comes up in today's design review. What is the right answer?
• A team plans to skip business analysis entirely and let watsonx Code Assistant for Z decide which systems to modernize and how. What is the flaw in this plan?
• The review team keeps hearing the assumption that every transformed workload must move off IBM Z as a matter of course. What is the flaw in that assumption?
• A pilot modernization stalls because the team relied on prompt engineering skill alone. What is most likely missing?
• A proof of concept is being turned into a governed modernisation plan. Why does 'convert every module into its own microservice' fail as a general guideline?
• A customer asks which mainframe modernization activities they can expect watsonx Code Assistant for Z to speed up. What is the accurate answer?
• The deployment target for a transformed workload was chosen because it ran fastest in the proof-of-concept demo. What is missing from that decision?
• Why should mainframe subject-matter experts stay involved after project kickoff rather than being excluded once requirements are gathered?
• A customer wants to run a modernization project using only their Java development team, without mainframe or testing specialists. What risk should a consultant flag first?
• A senior engineer reviews the current modernisation plan and flags that every existing call between two modules would be reproduced unchanged in the new environment. What has this plan failed to do?
• During a pilot, a team notices they are relying on the tool's transformation output without any operational risk review before promoting it. What does this indicate about how they are using the tool?
• The integration section of the deployment plan says nothing about connecting the transformed workload to existing enterprise systems. What is the concern?
• During a pilot, generated Java code compiles cleanly and the team decides to skip further testing. What is wrong with that decision?
• A governed modernisation plan growing out of a proof of concept must choose between three architectural extremes. Which approach is defensible?
• A customer wants to convert their entire mainframe portfolio with watsonx Code Assistant for Z before assessing which applications are worth modernizing. What should the consultant point out?
• A proof of concept is being scaled up into a governed rollout, and the deployment decision now needs to weigh factors the PoC never had to consider. Which factor newly needs that weight?
• A customer plans a scalable modernization programme and asks which project roles matter most. What should the consultant emphasise?
• The current plan justifies each proposed API and modular boundary by referencing a specific business or technical driver, a detail worth checking. What does this indicate about the plan?
• Which statement best summarises what watsonx Code Assistant for Z is for, and what it leaves to the team?
• Two candidate deployment options for a transformed workload are on the table, and the review needs to settle which choice matches the recommended selection approach.
• Which statement best summarises what a modernization project needs beyond generating Java from COBOL?
• Which summary best captures how modular services, APIs and hybrid-cloud patterns should be used when modernising a mainframe application?
