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).

Examining the test basis is an appropriate task for the Test Analyst during the test analysis phase, as it involves identifying and evaluating the sources of information for test analysis, such as requirements, design documents, user stories, etc. Reviewing test estimates, creating a test execution schedule, and evaluating status against exit criteria are tasks that belong to other phases of testing, such as test planning, test implementation, and test closure.

Comprehensive and Detailed In-Depth Explanation:

A (Use case testing):Not suitable as it focuses on user interactions rather than combinations of input values.

B (State Transition testing):Irrelevant since the focus is not on state changes.

C (Equivalence partitioning):Good for partitioning input values but not efficient for combinations.

D (Pairwise testing):Correct. This technique is highly efficient for coveringcombinations of multiple variableswith fewer test cases, which is crucial when the schedule is tight.

Therefore, the correct answer isD (Pairwise testing).
