Which of the following is a typical output of static data flow analysis?

The exact line numbers where the program crashes

A report of potential uninitialized variable uses

A list of runtime errors encountered during execution

The execution time of each function

What is the primary purpose of data flow analysis in software testing?

To trace the definition and use of variables to detect anomalies and guide testing

To ensure that the software meets all user requirements

To measure the execution speed of the code

To verify that all code statements are syntactically correct

In which two types of analysis can data flow analysis be applied?

Black-box and white-box testing

A test team is deciding between all-uses and all-du-paths coverage for a module with a loop that contains a definition and a use of the same variable. The loop can iterate up to 100 times. What is the main trade-off?

All-du-paths requires testing every path from the definition to the use, which could be enormous due to loop iterations, while all-uses only requires one path per def-use pair

All-du-paths is easier to achieve than all-uses because it only requires one path per definition

Both criteria require the same number of test cases because they both focus on def-use pairs

All-uses requires testing every path from the definition to the use, which could be enormous, while all-du-paths only requires one path per def-use pair

How does static data flow analysis detect anomalies?

By measuring code coverage during test execution

By executing the code with test data and observing variable values

By running the code in a debugger and setting breakpoints

By analyzing the source code without executing it

Data Flow Analysis CTAL-TTA Practice Questions (Page 2)

Part of the Domain 3: Static and Dynamic Analysis domain, which makes up ~21% of our current practice bank. ISTQB does not publish an official question count, but from its 120-minute exam (~50–80 total, ~11–17 in this domain), expect 1–2 from this objective — we provide 32 practice questions to prepare you well beyond it.
