A project has limited time for regression testing. What is the most appropriate approach to balance regression scope with time constraints?

Include all test cases in the regression suite to ensure complete coverage

Prioritize regression tests for high-risk areas and defer lower-risk tests

Skip regression testing entirely to save time

Only test the new features and ignore existing functionality

Which criterion is most important when selecting test cases from an existing suite for regression testing?

The test case has never failed in previous executions

The test case is the shortest and quickest to execute

The test case was written by the most senior tester

The test case covers functionality that is at high risk of being affected by changes

When determining the scope of regression testing using risk analysis, what does the 'likelihood of change' refer to?

The frequency with which the functionality is used by end users

The probability that a defect will be introduced in an area due to changes

The number of test cases available for an area

The time required to execute the regression tests

A team is preparing for a release that includes a change to the database connection pool settings. This change is expected to affect the performance of all modules that access the database. The team has a limited regression budget. What should be the primary focus of regression testing?

No regression testing, since the change is only a configuration setting.

Performance tests for the most critical database-dependent modules.

Functional tests for all modules, since the change could affect any functionality.

Only the tests for the module that was originally changed.

When selecting regression test cases from an existing suite, what does 'coverage' refer to?

The percentage of requirements or code exercised by the selected test cases

The number of defects found in the previous release

The total time allocated for regression testing

The number of testers assigned to execute the tests

Determining the Scope of Regression Testing CTAL-TA Practice Questions (Page 2)

Part of the The Tasks of the Test Analyst in Risk-Based Testing domain, which makes up ~12% of our current practice bank. ISTQB does not publish an official question count, but from its 120-minute exam (~50–80 total, ~6–10 in this domain), expect 3–5 from this objective — we provide 24 practice questions to prepare you well beyond it.
