Pass ISTQB-CTAL-TA Exam Guide

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).

Comprehensive and Detailed in Depth Explanation:

Boundary Value Analysis (BVA)focuses on values at the edges of equivalence partitions, including just inside and just outside the boundary.

Therevised boundariesare:

£500 and £749for the new 5.5% fee band

£750 and £999for the 4.5% fee band

Testing bothvalid and invalid boundariesis essential to ensure accurate fee calculations.

The correct test cases are:

£499 (just below the lower boundary)

£500 (at the lower boundary)

£749 (at the upper boundary of the first band)

£750 (at the lower boundary of the second band)

£999 (at the upper boundary of the second band)

£1000 (just above the upper boundary)

Therefore, the correct answer isD (499, 500, 749, 750, 999, 1000).

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

Comprehensive and Detailed In-Depth Explanation:

Component Testing (C) focuses on individual components or units and does not address usability or role-based testing.

System Testing (D) is the first level where the complete and integrated system is tested as a whole. It includes testing non-functional requirements such as usability, accessibility, and suitability for different user roles.

User Acceptance Testing (A) and Beta Acceptance Testing (B) are done later and focus on validating the product according to user needs and real-world scenarios.

Since testing for role appropriateness and usability should start as early as possible in the testing lifecycle, the correct answer is D (During system testing).
