                    ISQI ISTQB Certified Tester Advanced Level Test Analyst (CTAL-TA v4.0) Sample Questions (Q12-Q17):

                    NEW QUESTION # 12
                    You are testing the functional correctness of an application which allows the driver of a car to control if the air that enters the passenger compartment is fresh or recycled. The car may be ordered in various configurations:
                    * Engine Size, can be: 1500cc, 1900cc, 2200cc, 2500cc
                    * Gearbox type, can be: automatic, manual 5-speed, manual 6-speed
                    * Cruise control, can be: yes or no
                    * Electric sunroof, can be: yes or no
                    It is expected that the most popular configuration will have a 1900cc engine and a manual 5-speed gearbox with cruise control and no electric sunroof. In order to achieve full BASE CHOICE coverage, how many configurations must be tested?

                    Answer: B

                    Explanation:
                    The correct answer is D . CTAL-TA v4.0 defines base choice coverage as a combinatorial coverage criterion where a base value is selected for each parameter, forming one base coverage item. Then, additional coverage items are created by replacing one base value at a time with each non-base value while all other parameters remain at their base values.
                    The base configuration is explicitly given: 1900cc engine , manual 5-speed gearbox , cruise control = yes , and electric sunroof = no . That gives the first test configuration. Then each non-base value must be tested once while the other values remain fixed at the base configuration. Engine Size has four values, so there are 3 non-base engine values: 1500cc, 2200cc, and 2500cc. Gearbox type has three values, so there are 2 non-base gearbox values: automatic and manual 6-speed. Cruise control has one non-base value: no. Electric sunroof has one non-base value: yes.
                    Total configurations = 1 base + 3 + 2 + 1 + 1 = 8 . Option A , 48, is exhaustive testing: 4 ร— 3 ร— 2 ร— 2. Options B and C do not match the base choice formula. Reference: CTAL-TA v4.0, Section 3.1.2 Combinatorial Testing .


                    NEW QUESTION # 13
                    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.
                    System testing has finished and the test manager has asked you, the senior TA, to identify any parts of the product that should be focused on during acceptance testing. The results of this may be used to adjust the acceptance test plan.
                    You are using defect cluster analysis, only counting defects with severity levels 1 to 3, ignoring low severity levels 4 and 5. Function point analysis was used for estimating, so you have used function points as the unit of size for the various functional areas of the product. No numeric estimates of expected defect quantities were made for them individually but, as a result of product risk analysis, these functional areas have been ranked according to the amount of product risk that was predicted in them, with risk ranking 1 being the highest and
                    5 the lowest; the thoroughness of the testing performed so far has been proportional to that. The results are presented in the table below.
                    Functional area
                    Total function points

                    30
                    Which functional areas would you recommend for more test focus in acceptance testing?
                    a) Purchase Request entry
                    b) Purchase Request workflow
                    c) Purchase Request authorization
                    d) Supplier Identification
                    e) Purchase Order creation

                    Answer: C

                    Explanation:
                    The correct answer is C because defect cluster analysis must not be based on raw defect counts alone. CTAL- TA v4.0 states that after testing, the Test Analyst can identify actual defect-prone areas and compare predicted versus actual defect clusters; where discrepancies appear, more rigorous testing may be needed in those areas.
                    Here, size must be normalized using function points. The defect densities are: Purchase Request entry 30
                    /2000 = 15 defects per 1000 FP , Purchase Request workflow 15/1500 = 10 defects per 1000 FP , Purchase Request authorization 25/1000 = 25 defects per 1000 FP , Supplier identification 30/2000 = 15 defects per
                    1000 FP , and Purchase Order creation 30/1000 = 30 defects per 1000 FP .
                    The strongest actual clusters are therefore Purchase Order creation and Purchase Request authorization .
                    This is even more significant because authorization had the lowest predicted product risk ranking, 5 , so it should not have produced such a high defect density if the original risk assessment and test focus were accurate. Purchase Order creation also shows the highest defect density despite only medium predicted risk, ranking 3. Supplier identification and Purchase Request entry both have 30 defects, but they are larger areas and have only 15 defects per 1000 function points; Supplier identification was also the highest predicted risk area, so more defects there are less surprising.

                    NEW QUESTION # 14
                    You have been assigned as Test Analyst on a project that will deliver quotes for motor insurance. The amount quoted depends upon the combined values of twelve variables, that are resolved by a set of business rules.
                    What should be your MAIN task during the test analysis activity?

                    Answer: D

                    Explanation:
                    The correct answer is C because the question asks for the main task during test analysis , not test implementation, execution, or regression maintenance. CTAL-TA v4.0 states that during test analysis the Test Analyst checks the completeness of the test basis, gathers additional information relevant for testing, evaluates the test basis for defects and testability, and may model system behavior according to the test techniques to be applied. It also states that the TA defines and prioritizes test conditions traceable to the test basis.
                    In this motor insurance quoting system, the critical test basis is the combination of twelve variables resolved by business rules. The Test Analyst therefore needs to model how the quote is produced, most likely using a rule-based or combinatorial technique depending on how the rules are structured. That modeling exposes test conditions such as valid rule combinations, boundary cases, conflicting rules, missing rules, and high-risk variable interactions.
                    Option A relates more to selecting tests for execution, not analysis. Option B is regression test selection or adaptation, which CTAL-TA places under design/maintenance activities for regression tests, not the main initial analysis task. Option D is feedback from prior execution activity and is not the central task when analyzing a new rule-driven quote engine. Reference: CTAL-TA v4.0, Sections 1.2.1 Test Analysis and 3 Test Analysis and Test Design .


                    NEW QUESTION # 15
                    How is a Test Analyst involved in an Incremental SDLC model?

                    Answer: D

                    Explanation:
                    The correct answer is C . CTAL-TA v4.0 states that incremental development models divide the software into smaller, manageable increments, and each increment is developed and tested independently. Therefore, the Test Analyst performs the same core activities for each increment: test analysis, test design, test implementation, test execution, and test management support. The official CTAL-TA sample exam answer explanation confirms the same point: each increment is developed and tested independently, so the Test Analyst performs the same test activities for each increment.
                    Option A is not the best answer because "dynamic and adaptive" describes the Test Analyst's role more naturally in iterative or Agile contexts, where product evolution and feedback cycles drive adaptation. Option B is wrong because CTAL-TA explicitly notes that although the same activities are performed, the TA's work may be organized differently for each increment. Option D is wrong because incremental development is not necessarily cyclical; the official sample answer specifically rejects the idea that incremental development must be cyclical.
                    So the exam-safe distinction is: same activities in each increment, but not necessarily the same organization, timing, or cyclic structure . Reference: CTAL-TA v4.0, Section 1.1 Testing in the Software Development Lifecycle .


                    NEW QUESTION # 16
                    Your project is developing an application to process claims against insurance policies. Which of the following is a good example of CRUD completeness testing?

                    Answer: D

                    Explanation:
                    The correct answer is C because CRUD completeness testing is a static activity. CTAL-TA v4.0 defines CRUD as create, read, update, and delete, and states that CRUD testing verifies the lifecycle of data entities processed by the test item. The syllabus distinguishes two parts: CRUD completeness testing , which statically verifies whether all possible CRUD operations occur for every entity, and CRUD consistency testing , which dynamically checks whether functions interact correctly when handling the entity.
                    For an insurance-claims application, the key entity is the claim . A technical review checking whether the architecture/specification includes the ability to create, read, update, and delete claim records directly matches CRUD completeness. It is concerned with whether the full claim lifecycle has been included, not whether the lifecycle behaves correctly during execution. Option A is a strong example of CRUD consistency testing because it executes a lifecycle sequence and checks post-delete behavior. Option B is also dynamic execution, so it is not the best match for completeness. Option D is requirements elicitation completeness, not specifically CRUD completeness for the implemented claim entity. Reference: CTAL-TA v4.0, Section 3.2.1 CRUD Testing .
