Comprehensive and Detailed in Depth Explanation:

Pairwise testing is a combinatorial test design technique in which test cases are designed to execute all possible discrete combinations of each pair of input parameters. This technique significantly reduces the number of test cases compared to exhaustive testing while still covering pairwise interactions.

To calculate the number of test cases:

Colour: 4 options

Model: 3 options

Gigabytes: 4 options

Connectivity: 2 options

Pairwise testing does not necessarily involve multiplying all options, as it aims to cover all pairs. Using an orthogonal array or pairwise tool, the minimum number of test cases that cover all pairs for these parameters is16. Hence, the answer isC (16).

Comprehensive and Detailed in Depth Explanation:

Requirement Testability (a):The requirements are testable as they specify expected behavior, such as response time (4 seconds) and SSO control.

Consistency (b):There is inconsistency, as one requirement states no changes to screens, but another mentions a new data item for FCA registration.

Ambiguity (c):The requirements are clear in terms of what they specify.

Unique Identification (d):The requirements are listed as bullet points without unique identifiers, violating this criterion.

Versioning and Author (e):The document includes a version number, date, and author.

Therefore, the correct answer isD (b, d).

The test set B is the best test set to explicitly test on single boundary value fully, using boundary value analysis. Boundary value analysis is a technique that tests the values at or near the boundaries of an input domain. The boundaries for this scenario are:

Salary less than €20 000

Number of children at least three and less than six

The test set B tests the boundary values of each boundary (€19 999, €20 000, three children, six children) and one value inside each boundary (€19 998, €20 001, four children). Verified References: [ISTQB® Certified Tester Advanced Level Test Analyst CTAL-TA], Section 3.2.2, page 35.

Since the testing involves verifying theuser interface (UI) enhancementsand ensuring that they meet the needs of multiple user roles,Use Case Testingis the most appropriate technique.

Use Case testingallows you to validateend-to-end user scenariosand ensure the system behaves correctly for each role, focusing onuser interactions and usability.

Exploratory testing (A)might be useful for finding unexpected issues, but it lacks the structured approach needed for role-based UI validation.

Boundary Value Analysis (B)is useful for testing numeric input limits, not UI roles.

Pairwise testing (D)focuses on combinatorial testing, not role-based UI testing.

The correct answer isC (Use Case testing).

The technique that is most likely to support the required functional correctness testing is state transition testing. State transition testing is a technique that tests the behavior of a system or component based on its states and transitions between them. This technique is suitable for testing a system that has different modes or states depending on the input values or events, such as a car navigation system.
