                    ISQI ISTQB Certified Tester Advanced Level Test Analyst (CTAL-TA v4.0) Sample Questions (Q27-Q32):

                    NEW QUESTION # 27
                    You are your employer's most experienced TA. The organisation performs root cause analysis (RCA) thoroughly, but infrequently and only on individual defects that went live at the highest of the five Severity levels.
                    After six months of live operation for one system, particular concern has been expressed about the volume of usability and security defects and there is a strong desire to reduce their quantities. You have recommended adding product quality characteristics, per ISO 25010, to the defect report template.
                    How might this recommendation support RCA?

                    Answer: B

                    Explanation:
                    The correct answer is B . The organization already performs RCA, but only infrequently and only for individual live defects at the highest severity level. That approach misses recurring lower-severity or medium- severity defect patterns, especially where many defects share the same quality concern. CTAL-TA v4.0 includes supporting root cause analysis with defect classification and aligns the syllabus with the ISO/IEC
                    25010:2023 product quality model, including quality characteristics such as functional suitability, usability, security, compatibility, and others.
                    Adding Quality Characteristic to the defect report template enables defects to be grouped by the quality attribute they affect. Combined with Severity , this allows the team to isolate clusters such as high-volume usability defects or serious security defects and then perform RCA on a meaningful defect group rather than only on isolated live failures. That directly supports the stated goal: reducing the quantities of usability and security defects.
                    Option A is partly useful because Pareto analysis can identify high-volume categories, but by itself it is defect counting, not the strongest RCA support. Option C concerns defect detection percentage, which is a different analysis objective. Option D is weak because "how the defect was fixed" may help investigation, but it does not provide the systematic classification needed to target recurring root causes. Reference: CTAL-TA v4.0, Sections 5.3.2 Supporting Root Cause Analysis with Defect Classification and Appendix F Software Quality Model .


                    NEW QUESTION # 28
                    In your role as a Test Analyst for the development of a business application, you asked the Product Owner to help you understand how the various product risks would affect the users.
                    Which product risk management activity was this?

                    Answer: A


                    NEW QUESTION # 29
                    In which of the following circumstances is the transition from a high-level test case to a low-level test case MOST LIKELY to be deferred from test design to test implementation?

                    Answer: D

                    Explanation:
                    The correct answer is D . CTAL-TA v4.0 distinguishes between high-level test cases and low-level test cases
                    . A high-level test case describes the circumstances under which the test object is examined and indicates the test conditions covered, but it does not provide concrete preconditions, input data, expected outputs, or postconditions. A low-level test case is the detailed refinement of that high-level test case and specifies concrete test data, tester actions, expected results, and postconditions.
                    The syllabus explicitly states that the transition from high-level to low-level test cases is often deferred from test design to test implementation, especially if specific test data is needed . This is because concrete test data may depend on available databases, valid account records, configured environments, external interfaces, data privacy restrictions, or generated identifiers. Until those implementation details are known, a high-level test case may remain abstract.
                    Option A is incorrect because the execution schedule affects sequencing, not necessarily the abstraction level of a test case. Option B argues for making the test case more understandable, not deferring refinement. Option C is wrong because product risk analysis should guide test prioritization and coverage, but it is not the direct reason for delaying low-level test-case derivation. Reference: CTAL-TA v4.0, Section 1.3.1 High-Level Test Cases and Low-Level Test Cases .


                    NEW QUESTION # 30
                    You are working on a project to build a purchasing system. The main requirements for the system are that it shall:
                    * Allow users to enter details of items that they wish to have purchased and, from these details, create a purchase request.
                    * Take each purchase request through a workflow that will allow the requestor's line manager to approve the request, reject it or return it for clarification / modification.
                    * Forward approved requests to the Purchasing Department.
                    * Allow purchasers to find the best available supplier for each approved request and place the request on that supplier as a purchase order.
                    The solution is being developed according to the company's traditional V-model methodology. The requirements are clearly documented and include a business process model. Operational profiles have been created to guide performance testing.
                    Initial item entry will involve a check that each item entered exists on the master stock file and that the user is entitled to request it; this depends on user role and grade. Line manager authorization will be assisted by a recommendation made by the system according to relevant business rules, although the manager can override this recommendation. For approved requests, the workflow will continue to support the process through to placing of the purchase order.
                    Planning has begun for system testing and the Test Manager has asked you, the senior TA, to help with it.
                    What would be the MOST effective techniques for functional testing of this project?
                    a) Combinatorial testing
                    b) Random testing
                    c) CRUD testing
                    d) State transition testing
                    e) Scenario-based testing
                    f) Decision table testing
                    g) Exploratory testing

                    Answer: C

                    Explanation:
                    The correct answer is D because the scenario gives three strong test-basis signals: a workflow, a business process model, and business rules. CTAL-TA v4.0 classifies relevant black-box techniques into data-based, behavior-based, and rule-based techniques, and explicitly includes state transition testing, scenario-based testing, and decision table testing within Chapter 3 test analysis and design. It also requires the Test Analyst to select appropriate techniques for a given situation.
                    State transition testing fits the purchase request workflow because requests move between states such as created, approved, rejected, returned for clarification, forwarded, and converted to purchase order. CTAL-TA states that behavior-based techniques derive tests from state-dependent or dynamic behavior. Scenario-based testing fits because the requirements include a business process model and end-to-end purchasing flows.
                    CTAL-TA states that scenario-based testing evaluates behavior in realistic workflows and may use activity diagrams, use cases, flowcharts, or BPMN models. Decision table testing fits because entitlement checks and manager recommendations are driven by business rules involving role, grade, and authorization logic. Rule- based techniques verify stateless business-rule behavior.
                    Combinatorial testing may help with input combinations, but it is not the best overall functional set here.
                    Random and exploratory testing are weak choices because the requirements are clear and formal.


                    NEW QUESTION # 31
                    You are testing a program which calculates the best airspeed for optimal fuel economy of a new type of aero engine. The result depends on atmospheric pressure at the airplane's current height, the air temperature at the airplane's current height, and on the airplane's current fuel load. The best airspeed:
                    * decreases by 4 knots (nautical miles per hour) for every 5mb (millibar) decrease in atmospheric pressure,
                    * increases by 6 knots for every 1°C decrease in air temperature,
                    * increases by 1 knot for every 1,000kg decrease in fuel load.
                    You have a test case which predicts that at an atmospheric pressure of 1,000 mb, an air temperature of 10°C and a fuel load of 400,000kg, the optimal airspeed for an Airbus A380 is 600 knots.
                    Which test case would verify the metamorphic relation described in the three bullet points above?

                    Answer: C

                    Explanation:
                    The correct answer is A . CTAL-TA v4.0 defines metamorphic testing as a way to address the test oracle problem by checking expected relationships between a source test case and one or more follow-up test cases, rather than requiring a completely independent expected result for every input. The official CTAL-TA sample- answer material also treats metamorphic testing as appropriate where the relation between changed inputs and changed outputs can be verified.
                    Start with the source test case: 1000 mb, 10°C, 400,000kg = 600 knots . In option A , pressure decreases from 1000 mb to 950 mb , a drop of 50 mb . Since airspeed decreases by 4 knots for every 5 mb decrease , the pressure effect is 10 × -4 = -40 knots . Temperature remains 10°C , so the temperature effect is 0 . Fuel load decreases from 400,000kg to 360,000kg , a drop of 40,000kg . Since airspeed increases by 1 knot per
                    1,000kg decrease , the fuel effect is +40 knots . Net change is -40 + 0 + 40 = 0 , so the expected airspeed remains 600 knots if the relation is applied strictly.
                    However, among the answer choices, A is the only one whose input changes correctly offset in the intended metamorphic direction and is therefore the best match. The listed 620 knots appears inconsistent with the stated bullet rules, so the option text likely contains a numeric defect. The defensible relation-based selection is still A .
