2. 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?

Which type of defect should you report as part of the code review?

A) Too many nested levels
B) Unreachable code
C) No defects should be reported, code is correct.
D) Endless loop

4. Which of the following statements is TRUE regarding tools that support component testing and the build process?

A) Both are used to examine source code before a program is executed. This is done by analysing a section of code against a set (or multiple sets) of coding rules.
B) Both provide an environment for unit testing in which a component can be tested in isolation with suitable stubs and drivers.
C) Both are used to reduce the costs of test environments by replacing real devices.

5. Consider the following specification:

If you are flying with an economy ticket, there is a possibility that you may get upgraded to business class, especially if you hold a gold card in the airline's frequent flier program. If you don't hold a gold card, there is a possibility that you will get 'bumped' off the flight if it is full when you check in late.
This is shown in the control flow graph below. Note that each box (i.e., statement, decision) has been numbered.
Three tests have been run:
Test 1: Gold card holder who gets upgraded to business class
Test 2: Non-gold card holder who stays in economy
Test 3: A person who is bumped from the flight
What is the level of decision coverage achieved by these three tests?

A) 67%
B) 75%
