質問 3：
You are developing the code that controls an industrial Espresso machine which will be operated by waiting staff in restaurants.
The machine is rather complicated and has lots of switches and buttons, so in the next iteration instructions will be provided to the operator on a small LCD screen.
A User Story for the Operator-Instructions module is as follows:
"As an operator of the Espresso machine, I would like to know how to steam milk, so I can add steamed milk to the coffee." The following is a list of risks identified for this story, with assigned probability and impact.
A. A small child may try to steam milk. Probability: High. Impact: Low
B. Operators will not read the instructions and will try various switches and buttons until something works.
Probability: Low. Impact: Low
C. The instructions may be incorrect or appear in the wrong order. Probability: Low. Impact: High
D. An untrained customer will attempt to use the coffee machine. Probability: High. Impact: High

質問 7：
Which of the following statements about the differences between testing activities in Agile projects and traditional projects is true?
A. In traditional V-model projects the different test phases are performed sequentially, while in Agile projects these phases are performed parallel to one another within each iteration
B. Because Agile projects tend to adopt test-first approaches, test automation in Agile projects is performed at lower test levels, while test automation in traditional projects is performed at higher test levels
C. In traditional V-model projects there is a system test level that usually involves executing functional tests as well as non-functional tests, while in Agile projects there is never a system test level
D. Risk-based testing can be adopted both in Agile projects and traditional projects. In Agile projects, the specific risks for all of the iterations are identified and assessed during release planning
