Q. 57: A car manufacturer is updating its airbag deployment system for its family cars. It has increased the number of airbags from four to nine. This has necessitated an upgrade to the airbag control software (ACS) to allow deployment of the extra airbags where appropriate.
The car manufacturer receives information from on-board sensors. From this, it calculates the amount of deployment needed (minimal, medium and full), and from which airbag(s). For this upgrade, it will receive information from extra sensors to be used in its calculations.
The car manufacturer employs its own in-house software development team. It uses the V model for its software development. There are four stages of testing, from unit through to factory acceptance testing.
The development team is made up of project, programming and test managers. The programmers use object-oriented methods for development.
The car manufacturer wishes to be first to market with the extra airbags, which will allow it to increase the safety ratings for its family cars, thereby increasing sales in a very competitive market.
Which of the following are risks associated with the use of the V model for this upgrade?
I. The sensors may not be responsive enough in impacts.
II. The manufacturer may not be able to process the information received from the sensors quickly enough.
III. The time required to create the high- and low-level designs may mean that insufficient time can be spent on system testing.
IV. The system may fail factory acceptance testing, necessitating costly rework.
A. I and II
B. II and III
C. III and IV
D. I and IV
Explanation in favor of the correct Answer:
Option I refers to the functionality of the application. It is not life cycle dependent.
Option II also refers to application functionality, thus is not dependent on the life cycle being used.
Option III refers specifically to the V model requirement for high- and low-level designs, and thus is applicable.
Option IV refers to rejection at the final stages of validation, a key risk of the V model.

The car manufacturer wishes to be first to market with the extra airbags, which will allow it to increase the safety ratings for its family cars, thereby increasing sales in a very competitive market.
Which of the following is a risk associated with the development approach?
A. Information hiding may pose extra testing challenges.
B. System testing may take longer than planned.
C. The calculations may become overly complex due to the increase in the number of sensors.
D. Testers may not be able to write the factory acceptance tests at the start of development
Explanation in favor of the correct Answer:
Answer B refers to a project risk, it is not specific to the use of object-oriented methods.
Answer C refers to application functionality and its complexity. This is not specific to the use of object-oriented methods.
Answer D is a risk associated with the use of the development life cycle, the V model, not the development approach.

The car manufacturer wishes to be first to market with the extra airbags, which will allow it to increase the safety ratings for its family cars, thereby increasing sales in a very competitive market.
Which of the following is a product risk of the upgrade described?
A. The extra airbags may restrict the visibility of the driver.
B. The manufacturer may not be awarded its desired safety rating.
C. There may be a need to use modeling tools at unit testing.
D. The ACS may not be able to process the extra sensor data quickly enough, causing incorrect deployment of the airbag(s).
Explanation in favor of the correct Answer:
Answer A refers to usability of the airbags in the car. The upgrade is concerned with airbag deployment, not its impact in use (although this should of course have already been considered before the upgrade was requested).
Answer B refers to an activity independent of the challenges of development. It refers to the finished product, not specifically the ACS upgrade.
Answer C refers to a project risk of a requirement for use of a tool, which may increase costs and introduce a need for training.
