iSQI CTFL-AcT Exam With Confidence Using Practice Dumps

Security requirements specify how a system should handle access control, data protection, confidentiality, integrity, and authentication. In acceptance testing, validating that users cannot access data or functions they are not authorized for is a critical test objective when dealing with security.

Option D is correct because it directly relates to access control — a fundamental aspect of security. Ensuring that “normal users shall have restricted access to private data” reflects both a security requirement and a condition that must be tested for compliance.

Other options:

A relates to performance (response time).

B refers to architecture or platform (web-based system).

C is about UI design and usability (style compliance).

Only D addresses security specifically.

Answer: D. Normal users shall have restricted access to private data.

Poorly defined requirements are a leading cause of defects and project failure. According to the ISTQB CTFL Acceptance Testing Syllabus and IQBBA FL Syllabus, the quality of requirements plays a critical role in successful solution development and acceptance testing. Requirements must be clear, unambiguous, complete, and testable. When they are vague or ambiguous, stakeholders may interpret them differently, which can lead to incorrect implementations, inadequate testing, and ultimately rework or rejection during acceptance.

Option A is explicitly supported by the ISTQB Foundation Syllabus and IQBBA principles. In contrast:

Option B is incorrect because Agile lifecycles still place great emphasis on requirement engineering, even though requirements evolve iteratively.

Option C misrepresents INVEST: it is a guideline for writing good user stories but does not replace reviews or validation techniques.

Option D is risky and not endorsed by ISTQB. While testers may identify ambiguities, the correct approach is to clarify them with all relevant stakeholders, not make assumptions.

Exact Reference – ISTQB CTFL Acceptance Testing Syllabus (Section 1.3.1):

“Ambiguous, incomplete, or inconsistent requirements increase the risk of misunderstanding between stakeholders, leading to incorrect implementation and ineffective tests.”

Exploratory testing is an unscripted, experience-based testing technique where the tester learns about the system, designs tests, and executes them simultaneously. It is especially effective in Agile environments, where rapid feedback and creative exploration are valuable.

Option D is the least likely action because scripting automated test scripts is a structured activity that typically occurs after exploratory sessions or during more formal test phases. Exploratory testing emphasizes manual exploration, not automation scripting.

Other options:

A is part of the core purpose of exploratory testing — discovering the product.

B is relevant — defining a charter and discussing it with stakeholders (like the Product Owner) helps guide the exploratory session.

C is also relevant — results of exploratory tests should be documented and communicated.

Answer: D. Scripting of the automated test scripts
