What is a key benefit of back-to-back testing for AI-based systems?

It removes the need for test data

It ensures the new version is always better than the old one

It guarantees that all defects are found

It eliminates the need for a separate test oracle

Which situation is a good candidate for applying back-to-back testing?

Evaluating the model's accuracy on a labeled test set

Testing the user interface of an AI application

Comparing two different implementations of the same AI algorithm

Measuring the model's training time

How can non-deterministic outputs be handled in back-to-back testing?

By ignoring the outputs and only testing the code structure

By running each version only once and comparing the single outputs

By assuming that all non-deterministic outputs are defects

By using statistical measures to compare the distributions of outputs

In back-to-back testing, what is the primary basis for detecting defects?

Comparing outputs against historical performance metrics

Comparing outputs against user expectations

Comparing outputs against a formal specification

Comparing outputs of different versions against each other

When comparing outputs from two versions of an AI system, what should a tester consider?

Only exact matches are acceptable; any difference indicates a defect

Both exact matches and acceptable differences should be considered

Differences are always acceptable if the versions are different

Only differences in the final output matter, not intermediate results

Back-to-Back Testing CT-AI Practice Questions (Page 3)

Part of the Domain 9: Methods and Techniques for the Testing of AI-Based Systems domain, which makes up ~13% of our current practice bank. ISTQB does not publish an official question count, but from its 60-minute exam (~25–40 total, ~3–5 in this domain), expect 1–1 from this objective — we provide 29 practice questions to prepare you well beyond it.
