A medical company has performed a safety criticality analysis using the IEC61508 standard. The software components to be developed have been categorized by Safety Integrity Level (SIL). Most components have been rated at SIL 1 or 2, and a few components at SIL 4.
After some discussions with the QA manager, the project has decided to adhere to the recommendations for test coverage provided by the IEC61508 standard.
Which level and type of test coverage should at least be used for the components rated at Safety Integrity Level (SIL) 2?

• A. 100% statement coverage and 100% decision coverage
• B. 100% statement coverage
• C. 100% statement coverage, 100% decision coverage and 100% multiple condition coverage
• D. 100% statement coverage, 100% decision coverage and 100% MC/DC coverage

Within the world of consumer electronics, the amount of embedded software is growing rapidly. The amount of software in high-end television sets has increased by a factor of about eight over the last six years. In addition, the market of consumer electronics has been faced with a 5 -10% price erosion per year. The price of a product is, among a number of other things, determined by the microcontroller used. Therefore, the use of ROM and RAM remains under high pressure in consumer electronic products, leading to severe restrictions on code size.
Within a new high-end TV project, it has been decided to apply dynamic analysis.
Which of the quality goals listed below is MOST appropriate to the project context?

• A. Prevent failures from occurring by detecting wild pointers and loss of system memory.
• B. Analyse system failures which cannot easily be reproduced.
• C. Evaluate network behaviour.
• D. Improve system performance by providing information on run-time system behaviour.

Which of the following is a valid reason for including security testing in a test approach?

• A. To evaluate the ability of a system to handle peak loads at or beyond the limits of its anticipated or specified workloads
• B. Software changes will be frequent after it enters production.
• C. To provide measurements from which an overall level of availability can be obtained.
• D. There is a threat of unauthorized copying of applications or data.

Consider the following fault attack:
* Force all possible incoming errors from the software/operating system interfaces to the application.
Which of the following is the kind of failure you are looking for when using this attack?

• A. Application crashes when the network is unavailable.
• B. Application miscalculates total monthly balance due on credit cards.
• C. Application crashes due to a lack of portability.
• D. Application crashes when unsupported characters are pasted into an input field.

A software company based in Spain that develops mobile applications expects many small updates in the future, e.g., due to changing configurations and customer feedback. The company also wants to focus on being able to change the software effectively and efficiently during initial development without introducing new defects.
Which maintainability sub-characteristic should be covered by the test approach during the initial development?

• A. Modularity
• B. Re-usability
• C. Analysability
• D. Modifiability
