Which statement regarding AUTOSAR Is TRUE?
AUTOSAR describes…

…a collection of characteristics of the performance of processes of an organization.

…an open and standardized software architecture for vehicle development.

…an analysis unit, which processes Input signals and determines intermediate values and their respective output signals by using existing information.

…activities, methods and measures to achieve functional security for electric and electronic solutions.

Explanation
https://www.pathpartnertech.com/software-architecture-autosar-for-automotive-embedded-system/ AUTOSAR (AUTomotive Open System ARchitecture) is an open and standardized software architecture for vehicle development, enabling the development of safety-relevant automotive software components. It provides a common platform for the development of software components from different suppliers, and thus enables the integration of multiple ECUs in a vehicle.

QUESTION 17
You are working as a .module tester* (syn. unit tester, component tester) in an automotive project for the development of a control unit for an electric window. During white-box lest design, you come atomic requirements: B1 AND (B2 OR B3). The task for you is to design test cases according to the principle of the modified condition/decision testing (MOOC). You have already designed three test cases:
1) B1 = TRUE, B2 = TRUE, B3 = FALSE
2) B1 = TRUE, B2 = FALSE, B3 = TRUE
3) B1 = FALSE, B2 = TRU, B3 = FALSE
Which of the following test cases is necessary to achieve 100% modified condition/decision coverage?

B1 = FALSE, B2 = FALSE, B3 = TRUE

B1 = FALSE, B2 = FALSE, B3 = FALSE

B1= TRUE, B2 = TRUE. B3 = TRUE

B1 = TRUE, B2 = FALSE, B3 = FALSE

Explanation
To achieve 100% condition/decision coverage, all possible combinations of the three Boolean variables B1, B2, and B3 must be tested. The three test cases provided only cover three of the eight possible combinations.
The fourth test case, C, covers the remaining combination of B1 = TRUE, B2 = TRUE. B3 = TRUE, ensuring 100% coverage.

QUESTION 18
In the release process, which of the following work products. Information and documents are the typical output of the tester?

Tested lest objects

Insulation recommendation

Non-detected defects

Change request

Explanation
When the tester is engaged in the release process, they are typically expected to produce several work products, including an insulation recommendation. This document provides a summary of the results of the tests conducted and provides an overall assessment of the test results. The insulation recommendation should include an assessment of the quality of the tested product, details of any critical or major defects detected, and any other relevant information. The insulation recommendation should also include any proposed changes or improvements to the software that could be made to increase the quality of the product.

QUESTION 19
You are a tester In a learn and you are supposed to test diagnostic functions and bus communications on the CAN bus. The development team provides you with compiled software code and control unit hardware. Which test environment Is the best choice considering the test types?

A MiL test environment, as the compiled software code can be Integrated cost efficiently into an environment model.

A Sal test environment, since the performance of the bus communication can be tested better in this test environment.

A hi test environment, as the bus communication with other participants can be tested dose to reality

Diagnosis functions and bus communications can only be tested In the vehicle.

Explanation
A Hi test environment is the best choice for testing diagnostic functions and bus communications on the CAN bus, as it is the most realistic test environment and allows for the testing of the bus communication with other participants. Hi test environments are also the most cost-efficient solutions for testing these types of functions due to the availability of realistic, cost-efficient environment models.

QUESTION 20
Which statement regarding the contribution of the tester to a safety culture is true?

The tester performs the hazard analysis and the risk assessment for the product at the beginning of the project.

The tester always takes the overall context of the product development Into account when she/he executes their tasks

In systems that could potentially lead to physical injury or damage to the health of people the tester analyses potential hazards.

The tester creates the hardware-software interface and provides this document to the safety manager

QUESTION 21
Which statement regarding the MiL design and use is true?

The objective of using a Hi test environment is mainly to find non-functional errors in the model

The HIL test environment is as complex as a MiL or SiL test environment with regards to the complexity of its parts

Typically, the test for the coned behavior of a control unit’s functions is performed on a component Hi.

In contrast to the MiL and Si test environments, pausing or stopping is possible in a HiL test environment thanks to a real the capable computer

Explanation
This is due to the fact that HiL test environments are based on simulated models and the hardware can be paused or stopped when necessary. This allows for more precise and efficient testing of the control unit’s functions.

QUESTION 22
Which of the statements regarding traceability in Automotive SPICES3.x is true?

The linking of requirements, test cases and test togs provides traceability and enables the desired verification of test cases for test case coverage

A1:N relation exists; for example If a test case is tested with the help of several requirements and is therefore linked to several requirements

The linking of a requirement, a derived test case and the associated test implementation provides the base for a complete testability.

With complete tractably It Is possible to trace test cases to their requirements and test cases which have been executed to their corresponding results.

QUESTION 23
Which statement regarding AUTOSAR Is NOT TRUE?

One of the objectives of AUTOSAR is to support the development of reliable systems.

One of the objectives of AUTOSAR Is the replicability of software components between different vehicle platforms and between different partners.

One of the objectives of AUTOSAR is cooperation regarding the standards and the implementation.

One of the objectives of AUTOSAR is the definition of a maintainable as well as adjustable open architecture.

Explanation
According to the ISTQB Certified Tester, Automotive Software Tester (CT-AUT) study guide, the objectives of AUTOSAR (Automotive Open System Architecture) include the definition of a maintainable and adjustable open architecture, the development of reliable systems, the replicability of software components between different vehicle platforms and between different partners, and cooperation regarding the standards and the implementation.

QUESTION 24
Which statement regarding ISO 26262 Is true?

According to thegeneral opinion of experts in functional safety, ISO 26262 CANNOT be considered as a contribution to the state of science and technology regarding the functional safety of road vehicles.

ISO 26262 Is part of Automotive SPICE Therefore, conformity with ISO 26262 is checked as part of an Automotive SPICE- assessment to avoidthe additional effort of a separate safety audit

ISO 26262 is a standard for functional safety. It is a domain-specific adaption of IEC 61508 for the specific characteristics in the development of safety relevant electric-electronic systems for motor vehicles.
D, ISO 26262 is a security standard; thus, information and work security are core topics of ISO 26262.

QUESTION 29
Which of the following measures is MOST suitable for dealing with the increasing complexity of product development?

Recruitment of additional employees

Use of experienced employees as coaches for new inexperienced employees

Creation of new subsidiaries(e g. Romania, India)

Use of several models as variants of a common platform

Explanation
One of the most effective ways of dealing with the increasing complexity of product development is through the use of several models as variants of a common platform. This strategy allows for a more efficient use of resources, as the base platform can be used and adapted for a variety of different products. Additionally, this strategy allows for more efficient testing, as the same tests can be used for multiple products. This approach also makes it easier to identify and fix any issues that may arise, as the same codebase can be used for multiple products.
