                    NEW QUESTION # 18
                    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.

                    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: B

                    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 # 19
                    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: C

                    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 × 3 × 2 × 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 # 20
                    The following activity diagram, drawn in Business Process Modeling Notation (BPMN), shows the process of raising a Purchase Request (PR), getting it authorized and raising a Purchase Order from it.

                    What is the minimum quantity of test cases that will be needed to cover all scenarios?

                    Answer: D

                    Explanation:
                    The correct answer is B , because the BPMN model contains two executable end-to-end scenarios . CTAL- TA v4.0 classifies scenario-based testing as a behavior-based technique where the Test Analyst creates a scenario model from action sequences that form workflows through the test item. The syllabus specifically mentions activity diagrams and BPMN-style workflow models as scenario-model sources, and states that test cases are designed to cover the identified scenarios.
                    In the diagram, the process starts when something is needed and the merchandiser enters the details of goods wanted. The manager then decides whether to authorize the PR. From that decision, there are only two real scenario outcomes. The first is the authorized scenario : the PR is authorized, the supplier is identified, the PR is updated and a Purchase Order is created, and the Purchase Order is sent. The second is the rejected scenario : the PR is rejected, the PR is cancelled, and the merchandiser considers the consequence of rejection.
                    The notification/result-of-authorization flow does not create separate scenarios; it is part of the same authorized or rejected process path. The note saying the merchandiser may try again is not a modeled loop because no BPMN flow returns to the start. CTAL-TA states that when the scenario model has no loops, each scenario can be tested with a separate test case. Therefore, the minimum quantity is 2 test cases .


                    NEW QUESTION # 21
                    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: D

                    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 # 22
                    You are working on an Agile project to develop a web-based online dating service that will allow members of the service to enter their profile, meet people who would be a good match for them, arrange social events with those people and to block people with whom they do not want contact.
                    The features for member profile entry have been delivered and tested. The current iteration will deliver profile matching. The regression tests for profile entry will be the acceptance criteria for its user stories. These tests have not been automated yet so you have decided to perform regression testing on the basis of a checklist.
                    Which checklist would be BEST in these circumstances?

                    Answer: C

                    Explanation:
                    The correct answer is A . CTAL-TA v4.0 describes checklist-based testing as an experience-based technique in which checklist items guide the tester and help avoid missing important checks. It distinguishes checklist use from fully scripted testing, but the checklist must still be concrete enough to support the objective of the test session.
                    Here, the goal is regression testing for profile entry. The scenario says the regression tests for profile entry will be the acceptance criteria for its user stories , but those tests have not been automated yet. Since the team needs to manually perform regression testing now, the best checklist is a read-do checklist built from the acceptance tests of the user stories. A read-do checklist is appropriate when the tester should read each item and perform it as an action. That fits manual regression execution: run this acceptance test, check the result, then proceed to the next item.
                    Option B is weaker because acceptance criteria are statements of expected behavior, not necessarily executable test actions. Option C is less suitable because a do-confirm checklist is used when tasks are performed from memory or normal workflow and then checked afterward; regression testing needs active, item-by-item execution. Option D combines both weaknesses: acceptance criteria instead of acceptance tests, and do-confirm instead of read-do.
