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

Comprehensive and Detailed in Depth Explanation:

Decision Table Analysis:

Age:Valid ranges (18-69), excludes those aged ≥70 or <18 (2 valid values).

Alcohol Consumption:≤14 units, >14 units (2 values).

Smoking Status:Smoker, Non-smoker (2 values).

Employment Status:Full-time, Not full-time (2 values).

After removinginfeasible combinations(like age <18 or ≥70), the possible combinations are reduced.

2 (age) x 2 (alcohol) x 2 (smoker) x 2 (employment) = 16possible combinations.

However, some combinations are logicallycollapsedor omitted, as irrelevant conditions are not covered.

After this collapsing, the total number ofnecessary test casesis8.

Therefore, the correct answer isB (8).

Comprehensive and Detailed in Depth Explanation:

InAgile projects, theTest Analyst’s involvementtypically startsat the beginning of the project.

Test Analysts workcollaboratively with developers, product owners, and other team membersfrom the outset to ensure thattesting is integrated into the development process.

Option A (Beginning of the first iteration)is too late since planning and discussing test approaches begin earlier.

Option B (After signing off user stories)contradicts the Agile principle of continuous involvement.

Option C (In parallel with coding)also occurs too late since testing considerations should start during planning.

The correct answer isD (At the beginning of the project).

Two cases are left when this decision table is collapsed. A decision table is a technique that shows the combinations of conditions and actions for a given scenario. A decision table that is collapsed eliminates the combinations that are invalid or impossible, such as having a scholarship without meeting the qualifications. The two valid cases for this scenario are:

C1 = Y, C2 = Y, C3 = Y, A1 = Y, A2 = Y

C1 = Y, C2 = Y, C3 = N, A1 = Y, A2 = N
