Which statement correctly describes the difference between an error, a defect, and a failure?A. An error is a mistake made by a person, a defect is a flaw in code or documentation, and a failure is observable incorrect behaviour.B. An error and a defect are the same thing, while a failure is when testing stops.C. A defect only exists in production systems, while errors occur during development.D. A defect only exists in production systems, while errors occur during development.Answer: AExplanation: A: Correct. Errors are human mistakes during development; defects are flaws in artifacts; failures occur when defects cause incorrect system behavior. B: Incorrect. Errors and defects are distinct; failures are observable system issues, not just stopping of testing. C: Incorrect. Defects can exist at any stage, not only in production. D: Incorrect. Failures result from defects in the system, not necessarily the test environment.Question 2. A mobile banking app team follows Agile sprints, writes automated tests alongside development, participates in daily stand-ups, and performs continuous integration testing. Which testing approach is applied?A. Sequential testing approachB. Phase-based testing approachC. Shift-left testing approachD. End-to-end testing approachAnswer: CExplanation: A: Incorrect. Sequential testing follows waterfall; testing occurs after development, not concurrently. B: Incorrect. Phase-based testing separates testing into phases, which doesn’t match continuous Agile integration. C: Correct. Shift-left testing integrates testing early and continuously with development to find defects sooner and reduce costs. D: Incorrect. End-to-end testing validates full workflows, not the methodology of integrating testing early.Question 3. A mobile banking app experiences a sudden crash when users attempt to transfer amounts exceeding their account balance. The development team claims this scenario was never specified in the requirements. What does this situation best illustrate?A. Developers are solely responsible for identifying missing requirements.B. Testing should only validate explicitly documented requirements.C. Defects only exist when requirements are violated.D. Testing can identify defects even when requirements are incomplete or missing.Answer: DExplanation: A: Incorrect. Requirement completeness is a shared responsibility among business analysts, developers, and testers. B: Incorrect. Effective testing also explores edge cases and scenarios not explicitly documented but critical for quality. C: Incorrect. Defects can exist even if all documented requirements are technically met, such as missing functionality or unexpected behavior. D: Correct. Testing can reveal defects beyond documented requirements, highlighting gaps in specifications and real-world usage scenarios.Question PatternQuestion 1: Knowledge-based/Concept-based QuestionQuestion 2: Scenario-based QuestionQuestion 3: Knowledge-based/Factual QuestionPreparation Strategy & Study GuidanceStudy Smart: Focus on high-weight topics — Test Techniques and SDLC Testing.Practice Timed Tests: Attempt 40 questions in 60 minutes to simulate real conditions.Review Thoroughly: Understand why other options are wrong to avoid trick questions.Use the Glossary: CTFL exams rely heavily on ISTQB-standard terminology.Target >80% in mocks: build a buffer above the 65% passing score.Repeat & Reinforce: Reattempt weaker chapters for retention.Why This Course is ValuableExact exam simulation (timed & scored)In-depth explanationsFull syllabus coverage (v4.0)Designed by certified ISTQB expertsLifetime updates & community Q&A supportTop Reasons to Take These Practice Exams6 complete, full-length practice tests (240 total questions)100% aligned with ISTQB CTFL v4.0 syllabusRealistic question phrasing and terminologyDetailed explanations for every answerAdaptive coverage across all learning objectivesRandomized question order for better exam realismLifetime updates includedAccess anytime — desktop or mobileMoney-Back GuaranteeYour success is our priority.
