NEW QUESTION # 13
A system will be developed to support the administration of table-tennis tournaments. The following requirements for the enrolment of entrants have been provided:
R1. High. The administrator shall be able to enter the entrant's name, address, phone number/s (mobile and/or home), email and social media handles. Validation rules for these data items are provided separately.
R2. High. The administrator shall be able to enter the entrant's current world ranking (up to 250) and their relationship with the tournament sponsors (i.e. clothing / equipment / endorsement).
R3. High. The administrator shall be able to enter the entrant's attendance history at previous events (i.e.
finalist / played / withdrew during event / withdrew before event).
R4. Medium. From the entrant's address the system shall derive whether or not the entrant lives locally and, on the basis of that combined with other rules that are provided separately, shall suggest how much of the tournament's overall prize fund should be offered to the entrant as their individual attendance fee.
R5. Low. The administrator should be able to change the suggested attendance fee and the system should then deduct this from the remaining prize fund balance accordingly.
You have been asked to review the requirements using perspective-based reading, from your viewpoint as the TA who will be writing functional correctness system test cases. Assume that the other rules referred to by requirements R1 and R4 have been reviewed and are satisfactorily testable. Which conclusion would you reach?
Answer: D
Explanation:
The correct answer is A . Using perspective-based reading, the TA must review the requirements from the viewpoint of someone who must derive functional correctness test cases. CTAL-TA v4.0 states that perspective-based reading requires reviewers to attempt to use the test basis to generate the work product they would derive from it; for a tester, that means attempting to create tests and checking whether all necessary information is present.
R1 is testable because the data-entry items are listed and the validation rules are explicitly provided separately and assumed testable. R4 is also testable because the derivation and attendance-fee rules are separately provided and assumed testable. R5 is testable as a functional rule: change the suggested attendance fee, then verify that the remaining prize fund balance is reduced accordingly.
The weak requirements are R2 and R3 . R2 does not fully define the valid model for "relationship with the tournament sponsors": it is unclear whether clothing, equipment, and endorsement are mutually exclusive, whether multiple relationships may apply, or whether "no relationship" is valid. R3 is also incomplete because "attendance history at previous events" is not fully defined: it is unclear whether this is one value, multiple event records, or a history per event, and some values overlap conceptually, such as finalist and played. These gaps prevent complete functional correctness test design. Reference: CTAL-TA v4.0, Sections

NEW QUESTION # 14
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 # 15
The following use case diagram shows the process of raising a Purchase Request (PR) and getting it authorized. Details are entered in batches; any that fail validation will be rejected and must be re-entered. The details will indicate whether the request is a normal one or an emergency one. Normal requests must be authorized by the department manager, who may refuse to do so. Emergency requests will be automatically authorized and reported to the manager.
The test strategy states that:
* all combinations of extensions and exceptions, as well as the main scenario, shall be tested
* loops shall get simple loop coverage where the maximum number of iterations for validation exceptions is 3 and the typical number is 2.
What is the minimum quantity of test cases that will be needed to obtain this coverage?
Answer: A
Explanation:
The correct answer is B , because the minimum required set is 6 test cases . CTAL-TA v4.0 explains that scenario-based testing derives tests from scenario models, including the main scenario plus alternative and exception flows. It also states that simple loop coverage requires testing a loop when it is skipped, executed exactly once, executed more than once using a typical number of iterations, and executed with the maximum number of iterations if possible. Here, the validation exception loop has maximum 3 and typical 2 , so the validation loop must be covered with 0, 1, 2, and 3 iterations.
The feasible scenario combinations are:
* Main scenario: normal request, validation succeeds, manager approves.
* Validation exception only, then normal approval.
* Emergency request only.
* Normal request refused by manager only.
* Validation exception combined with emergency request.
* Validation exception combined with manager refusal.
The validation loop iteration coverage can be distributed across the validation-related cases: one case with 1 failed validation, one with 2 failed validations, and one with 3 failed validations. The main scenario supplies the 0-iteration case. Emergency and manager-refusal scenarios cannot be combined because an emergency request bypasses normal manager authorization. Therefore, fewer than six tests would miss either a required feasible extension/exception combination or one of the required loop-coverage cases.

NEW QUESTION # 16
A written specification describes the rules for granting membership of your company's sports facility, whether it must be paid for if granted and whether free transport to and from the facility will be provided.
These actions depend upon employment status (permanent, temporary or probationary), the result of a medical exam (passed, failed or not taken) and whether the person is classed as a local resident. The best decision table that could be created from this specification is shown below.
Which of the following conclusions is correct?
Answer: A
Explanation:
The correct answer is A because the decision table has the correct structural completeness, but it exposes missing rules in the written specification. There are three condition dimensions: employment status has three values, medical exam has three values, and local residency has two values. Therefore, the complete decision table requires 3 ร 3 ร 2 = 18 rule columns , and the table contains exactly 18 rules. The unresolved entries appear in rules 17 and 18 , where the person is probationary , the medical exam is not taken , and local residency is either yes or no . Since all action cells for these two combinations are marked with question marks, the model has revealed that the specification does not define the required behavior for those cases.
CTAL-TA v4.0 places decision table testing under rule-based test techniques and states that it is used when behavior is determined by combinations of conditions, such as business rules. It is especially useful for finding omissions, inconsistencies, ambiguities, and gaps in rule specifications. Option B is wrong because the table has the correct number of columns. Option C is wrong because models are deliberately used to clarify text-based specifications. Option D is wrong because a decision table is the correct model type for condition-action business rules. Reference: CTAL-TA v4.0, Section 3.3.1 Decision Table Testing .
NEW QUESTION # 17
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 would like to purchase 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 system is being developed following an Agile SDLC. Risk-based testing is practiced informally, discussion about what testing each user story will need being done in a risk-driven way during story refinement, but there is no central product risk register. Testing is exploratory, except for the acceptance tests for each story's acceptance tests. Operational profiles have been created to guide performance testing.
Regression test automation started late. The team want to automate all acceptance tests for every user story, but the test automation engineers are still playing catch up. They started with the tests that were easiest to automate, so the functional and non-functional coverage of the regression test pack is incomplete and random.
The current iteration is delivering a major change to the approval workflow and you, as a Test Analyst, have been tasked with defining the regression testing.
Which techniques would be MOST effective for selecting regression tests?
a) History-based, driven by the results of the regression tests run so far b) Risk-based, driven by the product risks and their traceability to the tests c) Operational profile-based, driven by the likely patterns of use of the relevant transactions d) Coverage-based, driven by the coverage obtained from use of relevant test techniques e) Impact analysis, driven by consultation with technical stakeholders to identify what might be affected.
Answer: D
Explanation:
The correct answer is B because the most effective regression-selection combination in this situation is operational profile-based selection plus impact analysis . CTAL-TA v4.0 states that regression testing often cannot execute every regression test because of time, budget, environment, or data constraints, so appropriate regression tests must be selected and the scope must be reviewed every cycle. The syllabus identifies impact analysis as a regression selection technique that focuses tests on areas most likely to be affected by changed configuration items, and also recognizes operational-profile-based testing as useful for selecting tests according to likely usage patterns and critical business processes.
Here, the current change is a major approval workflow change , so impact analysis with technical stakeholders is essential to identify direct and indirect effects. Operational-profile-based selection is also appropriate because approval, rejection, clarification, forwarding, and purchase-order creation are transaction flows with realistic usage patterns. Option A is weak because history-based selection is unreliable when the existing regression pack is incomplete and randomly biased toward easy-to-automate tests. Option C is invalid because formal risk-based selection depends on product risks and traceability to tests, but the scenario explicitly says there is no central product risk register. Option D also includes the invalid risk-based pair.
