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

Comprehensive and Detailed in Depth Explanation:

A1-switch transitionin a state transition diagram is a direct move from one state to another without intermediate states.

FromScreen 1, the possible 1-switch transitions are:

Next:Moves toScreen 2

Back:Moves toMenu

Refresh:Stays onScreen 1

Sincerefreshcan be applied multiple times (loop), it is still considered as one transition.

Therefore, the number of 1-switch transitions fromScreen 1is3.

The correct answer isD (3).

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.

Comprehensive and Detailed in Depth Explanation:

The project has multipledrop-down fields with many values, resulting in numerous combinations.

Pairwise testingis ideal for testing combinations efficiently.

Since the project usesSCRUM methodology, it requiresexploratory testingto accommodate changes and rapid feedback during sprints.

Use case testing (Option A)is not suitable since the focus is on combinations rather than functional sequences.

Decision table testing (Option B)would be less efficient due to the large number of combinations.

Classification Tree (Option C)is more suitable for class-based testing, not pairwise combinations.

Thus, the correct answer isD (Pairwise and exploratory testing).
