Which of the following options describes a relevant aspect of the design of a test environment for software-ln-the-loop (SIL)?
Correct Answer:
D
Explanation
A HiL (Hardware-in-the-Loop) environment simulates real-world conditions by combining actual hardware components with software execution. The breakout box allows signal routing and monitoring between the test system and the real parts. A software compiler is needed to build and execute the code being tested. Real parts provide genuine hardware behavior rather than pure simulation. The other options mix incompatible elements or describe different test environments like MiL or SiL that use mathematical models instead of actual hardware.
Which statement regarding the comparison of the test levels In ISO 26262, ASPICE and CTFL Is true?
Correct Answer:
D
Explanation
Component tests verify individual software units or modules in isolation. Both SiL (Software-in-the-Loop) and MiL (Model-in-the-Loop) environments are well suited for this level because they allow developers to test code logic quickly without needing complete hardware integration. SiL executes actual code with simulated inputs. MiL uses mathematical models of the software behavior. HiL is typically used for higher-level integration testing with real hardware. Unit testing at very early stages may not require a full test environment at all.
Which of the following statements regarding MIL test environments is true?
Correct Answer:
B
Explanation
Automotive SPICE requires specific documentation to ensure traceability and quality across the development process. A test procedure specification describes the steps, conditions, and expected outcomes for executing tests. This document is mandatory for demonstrating compliance with ASPICE standards. Test case specifications and test logs are important but less critical for SPICE compliance than the procedure specification. Test environment documentation, while useful, is not explicitly required by the standard itself.
Which statement regarding coding standards Is most true?
Correct Answer:
C
Explanation
MISRA-C is a coding standard written specifically for C language development to prevent defects and unsafe code. The statement in option B contains an error. It says MISRA-C defines rules for object-oriented software like C++, but MISRA-C applies only to C, not C++. MISRA-C++ is the separate standard for C++ code. Option B is technically incorrect because it misidentifies the language scope. The other options either misrepresent what MISRA-C covers or confuse it with different standards.
Which statement about databases is INCORRECT?
Correct Answer:
A
Explanation
Modern automotive development faces increasing complexity from diverse requirements, strict safety standards, and intricate software systems. Using experienced employees as coaches helps transfer knowledge and best practices to newer team members. This human-centered approach builds capability across the organization systematically. Adding more resources without guidance often creates coordination problems. Simplified tools alone cannot address fundamental complexity. Strict requirements documents help but do not solve the knowledge transfer problem as effectively as direct coaching and mentoring do.
Your company produces electric windows and corresponding control units. The newest control unit for electric windows has repeatedly been problematic, which you think result from issues In the requirements, in particular, you noticed Bee following requirements in your first review.
Which of the following requirements for the system test violates at least one of the quality criteria of the ISO/IEC/IEEE 29148:2011 ?
ID; 12. When the central lock is activated, then all windows are automatically closed.
ID; 37 Given: the ignition q activated. When the button tor a window is pressed down, then the window moves down.
ID; 85: Given: the window moves up. When the window encounters resistance, then the window ttng motor stops.
ID; 142; Given: a door is open When the button for a window is pressed then the message M-85 is sent to the control unit
Correct Answer:
D
Explanation
The exam outline includes understanding how different standards relate to each other. ISO 26262 is the functional safety standard for automotive electronics. CTFL is the foundational testing certification. ASPICE focuses on development processes. These standards use different terminology for similar test levels. Component testing at the unit level is called software unit test in ISO 26262 and software component verification in ASPICE. They address the same testing scope even though the names differ. Understanding these equivalences helps professionals work across different standard frameworks in automotive projects.

FAQ
CTFL-AuT Exam FAQ
Common questions about the exam itself
What background do I need before taking CTFL-AuT?
Foundation Level Certified Tester (CTFL) is a pre-requisite to all other certifications in the ISTQB Certified Tester Scheme. You should already understand basic testing concepts and ideally have some hands-on software testing experience in your role.
How hard is the CTFL-AuT exam compared to the Foundation Level?
CTFL-AuT is a specialist extension at Foundation Level depth, not an advanced level certification. It is harder than CTFL because it assumes you already know CTFL material and applies those skills to automotive-specific contexts like ASPICE, ISO 26262, and HiL testing, which are new topics for most testers.
Which objective area in CTFL-AuT do most candidates struggle with?
Standards for the Testing of E/E Systems is the heaviest section and typically the most challenging because it combines three major frameworks (ASPICE, ISO 26262, AUTOSAR) and requires understanding how to map testing activities to each standard's requirements and capability levels.
How long should I study to prepare for CTFL-AuT?
For accredited training courses, the syllabus requires a minimum of 12 hours of instruction. Most candidates need an additional 20-30 hours of self-study and practice beyond formal training to prepare thoroughly for the exam.
What happens on exam day for CTFL-AuT?
The exam contains 40 questions to be completed in 60 minutes. You answer multiple-choice questions in a proctored environment, either in-person at a test centre or online with a proctor monitoring your screen and environment via webcam. Candidates taking the exam in a language that is not their native language are entitled to an additional 25 percent of exam time.
What is the passing score for CTFL-AuT and how is it calculated?
The passing score is 26 out of 40 questions correct, which equals 65%. Your score is reported as a percentage. There is no partial credit for questions. each question is either right or wrong.
How many times can I retake CTFL-AuT if I fail?
You can take the exams as many times as necessary to pass them. The fees for re-taking the exams and details of any rules on the minimum time interval allowed between exams will be available from your local ISTQB Member Board or Exam Provider.
How long is the CTFL-AuT certification valid once I pass?
ISTQB does not publish an expiry date for CTFL-AuT certifications. Your certification remains valid indefinitely, but the automotive industry standards (ISO 26262, ASPICE, AUTOSAR) evolve, so staying current with industry updates is a professional responsibility.
What job roles does CTFL-AuT prepare me for?
CTFL-AuT qualifies you for roles like automotive software tester, automotive test engineer, embedded systems tester, or test analyst working on E/E systems and safety-critical automotive components, particularly in companies following Automotive SPICE or ISO 26262 frameworks.
How does CTFL-AuT relate to other ISTQB certifications?
Foundation Level testers who have passed the CTFL Automotive Software Tester Specialist syllabus exam should be able to adapt the test techniques known from the ISTQB Certified Tester Foundation Level (CTFL) to the specific automotive project requirements. After CTFL-AuT, you can pursue Advanced Level certifications like CTAL-TA or CTAL-TT in your career.
