In a heap dump analysis for a Java application, which of the following findings would most strongly indicate a memory leak?

The heap dump shows that the total heap size is smaller than the maximum heap size.

A large number of instances of a particular class are retained, and the class is not part of the application's expected long-lived objects.

The heap dump shows that the garbage collector has run many times.

The heap dump shows a large number of unreachable objects that have been collected by the garbage collector.

A team is developing a C++ application that uses raw pointers for dynamic memory. To reduce the risk of memory leaks, which practice is most effective?

Manually call delete in every possible code path

Use global pointers to avoid passing pointers around

Add more comments to explain pointer usage

Use RAII (Resource Acquisition Is Initialization) and smart pointers

A development team wants to detect memory leaks in a large C++ codebase before running any tests. They need a tool that can analyze the source code without execution and identify potential leaks, such as missing delete calls. Which approach should they use?

Run a static analysis tool like Clang Static Analyzer

Monitor heap usage with a profiler during test execution

Instrument the code with logging statements to track allocations

Use Valgrind's memcheck tool on the compiled binary

When interpreting a memory leak report from a tool like Valgrind, what does the 'definitely lost' category typically indicate?

Memory that was freed but then accessed again, causing a use-after-free error.

Memory that was allocated but has no remaining references, and the program did not free it before exiting.

Memory that is shared between multiple threads and cannot be freed due to synchronization issues.

Memory that is still reachable but could be freed by the program, indicating a potential leak.

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 31 practice questions to prepare you well beyond it.
