Which combination of skills does a successful COBOL-to-Java modernization project actually require?
Select an answer to reveal the explanation.
Short Explanation
The tool writes Java. It doesn't design the architecture, test the result, or ship it—you still need COBOL and Java knowledge plus architecture, testing, and DevOps skills.
Full Explanation
The correct answer is the combination of COBOL and Java knowledge together with architecture, testing and DevOps skills, since the transformation touches all of them. Generating candidate Java is one step in a pipeline that also needs architectural judgement about service boundaries, a test strategy that proves equivalence, and a DevOps path that gets the result into production safely. The prompt-engineering-only option is incorrect because prompt engineering shapes what the tool produces but supplies none of the architecture, testing or delivery work the project also needs. The Java-only option is incorrect because Java skill without COBOL and mainframe context leaves the team unable to judge whether generated logic actually matches the original. The COBOL-only option is incorrect because COBOL skill alone does not cover designing, testing or deploying the target system. For the exam, describe modernization as a multidisciplinary effort, not a single skill applied once.
