Question #57

The following rules determine the annual bonus to be paid to a salesman of a company based on the total annual amount of the sales made (referred to as TAS).
If the TAS is between 50k€ and 80k€, the bonus is 10%. If the TAS exceeds 80k€ by a value not greater than
40k€, the bonus is 15%. Finally, if the TAS
exceeds the maximum threshold which entitles to a 15% bonus, the bonus is 22%.
Consider applying equivalence partitioning to the TAS (Note: 1k€ = 1000 euros).
Which one of the following answers contain only test cases that belong to the same equivalence partition?

A. TC1 = 90k€; TC2= 110k€; TC3=125k€: TC4=140k€

B. TC1 = 81 k€; TC2= 97k€; TC3=111k€; TC4=118k€

C. TC1 = 40k€; TC2= 46k€; TC3=51k€; TC4=53k€

D. TC1 = 79k€; TC2= 80k€; TC3=81k€; TC4=82k€

Question #59

Which ONE of the following options BEST describes the third test quadrant (Q3)?

A. This test quadrant contains functional tests, examples, user story tests, user experience prototypes, API testing, and simulations. These tests check the acceptance criteria and can be manual or automated.

B. This test quadrant is business-facing and criticizes the system. It contains exploratory testing, usability testing, and user acceptance testing.

C. This test quadrant is technology-facing and supports the team. These tests should be automated and included in the continuous integration (CI) process.

D. This test quadrant contains smoke tests and non-functional tests (except usability tests). These tests are often automated.
