A technical test analyst is evaluating the maintainability of a legacy system before a planned refactoring. The team wants to identify modules that are difficult to analyze and change. Which static analysis approach would provide the most direct evidence of poor analyzability and changeability?

Execute a set of predefined test cases and measure the time to complete them.

Perform a code review focused on naming conventions and indentation style.

Measure cyclomatic complexity and comment density for each module.

Run a memory leak detection tool during a stress test.

A team is adopting a new coding standard and wants to ensure that all new code adheres to it. They also want to identify modules that are likely to be difficult to modify in the future. Which static analysis technique would be most effective for both purposes?

Automated static analysis tool configured with the coding standard rules and complexity metrics

Manual code review by a senior developer focusing on logic errors

Running a test suite to check for functional correctness

Pair programming sessions to review code as it is written

A technical test analyst is tasked with assessing the maintainability of a monolithic application that is planned to be decomposed into microservices. The team has limited time and budget. Static analysis reveals high coupling between modules, while dynamic testing shows that a small change in one module causes failures in several others. Which combination of static and dynamic findings provides the strongest evidence for prioritizing refactoring efforts?

Low comment density in static analysis and high memory usage in dynamic testing

High complexity in static analysis and slow response time in dynamic testing

High coupling in static analysis and high failure impact in dynamic testing

Low cohesion in static analysis and low test coverage in dynamic testing

Maintainability Testing CTAL-TTA Practice Questions (Page 1)

Part of the Domain 4: Quality Characteristics for Technical Testing domain, which makes up ~14% of our current practice bank. ISTQB does not publish an official question count, but from its 120-minute exam (~50–80 total, ~7–11 in this domain), expect 1–2 from this objective — we provide 17 practice questions to prepare you well beyond it.
