ISTQB ISTQB-CTAL-TA Exam With Confidence Using Practice Dumps

Comprehensive and Detailed In-Depth Explanation:

A (Functional appropriateness):Verifies that the function serves its intended purpose but does not focus on accuracy.

B (Installability):Unrelated to computational accuracy.

C (Functional completeness):Ensures that all specified functionality is present, but not about accuracy.

D (Functional correctness):Correct. Sincecomputational accuracyis the primary concern, testing must focus on ensuring that all calculations are correct.

Therefore, the correct answer isD (Functional correctness).

Eight cases are required to test the tax system specification using a decision table that is not collapsed. A decision table is a technique that shows the combinations of conditions and actions for a given scenario. A decision table that is not collapsed contains all possible combinations of conditions and actions, regardless of whether they are valid or not. The conditions for this scenario are:

Salary less than €20 000

Married

Number of children more than two and less than five

The number of cases is equal to the number of possible combinations of these conditions, which is 2^3 = 8. Verified References: [ISTQB® Certified Tester Advanced Level Test Analyst CTAL-TA], Section 3.3.1, page 37.

Eight 0-switch test cases are needed to achieve 100% 0-switch coverage. A state transition test technique is a technique that tests the behavior of a system or component based on its states and transitions between them. A 0-switch test case is a test case that covers one state and its associated actions and events. To achieve 100% 0-switch coverage, all states and their associated actions and events must be covered by at least one test case. The states for this scenario are:

Enter PIN

PIN OK

PIN not OK

1st try

2nd try

3rd try

Access to act

Eat card
