ISTQB ISTQB-CTAL-TA Actual Questions

The risk impact for requirement R1 should be categorized as high or very high, as it is a business critical requirement that affects the core functionality of the system. The risk impact is determined by assessing the potential negative consequences of a failure or defect in the system. The other statements are not true, as they are based on assumptions or irrelevant factors. Verified References: [ISTQB® Certified Tester Advanced Level Test Analyst CTAL-TA], Section 1.2.1, page 13.

Comprehensive and Detailed in Depth Explanation:

Portability testing verifies that software can be transferred from one environment to another with minimal effort. It checks for installation, adaptation, and replacement issues.

a) Insufficient, unclear installation or de-installation instructions:This directly relates to portability because improper installation procedures can affect moving the software to different environments.

e) The stock control barcodes cannot be read by the replaced barcode scanner:This issue is associated with compatibility and adaptability between devices, which is crucial in portability testing.

Optionsb) and d)relate to usability and performance testing, not portability.

Optionc)relates to security or access control testing.

Therefore, the correct answer isA (a, e).

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).

Eight 0-switch test cases are needed to achieve 100% 0-switch coverage. A state transition test technique is a technique that tests the behavior of a system or component based on its states and transitions between them. A 0-switch test case is a test case that covers one state and its associated actions and events. To achieve 100% 0-switch coverage, all states and their associated actions and events must be covered by at least one test case. The states for this scenario are:
