ISTQB ISTQB-CTFL valid exam dumps : ISTQB Certified Tester Foundation Level (CTFL v4.0)

Which ONE of the following options MOST ACCURATELY describes the activities of "testing" and
"debugging"?

• A. Testing identifies a defect that is caused by an error in the software, whereas debugging is concerned with finding the causes of this defect, analyzing these causes, and eliminating them.
• B. Testing triggers a defect that is caused by an error in the software, whereas debugging is concerned with finding the causes of this defect, analyzing these causes, and eliminating them.
• C. Testing triggers a failure that is caused by a defect in the software, whereas debugging is concerned with finding the causes of this failure (defects), analyzing these causes, and eliminating them.
• D. Testing triggers a failure that is caused by a defect in the software, whereas debugging is concerned with finding the causes of this failure (defects), analyzing these causes, and reproducing them.

A requirement specifies that if the total amount of sales (TAS) made during the year by a corporate seller is
300,000€ or more, the bonus that must be paid to the seller is 100% of a certain amount agreed upon at the beginning of the year. The software contains a fault as it implements this requirement with the decision "IF (TAS = 300,000)" instead of "IF (TAS >= 300.000)". The application of the 3-value boundary value analysis to this problem consists of the following three test cases (TAS is an integer variable):
TC1 = 299,999 TC2=300,000 TC=300,001
Which of the following statements is TRUE?

• A. None of the three test cases would highlight the fault.
• B. TC3 would highlight the fault
• C. TC1 would highlight the fault
• D. TC2 would highlight the fault

Consider an estimation session in which a six-member Agile team (Memb1..... Memb6) uses the planning poker technique to estimate a user story (in story points). The team members will use a set of cards with the following values: 1,2, 3,5, 8,13,21. Below is the outcome of the first round of estimation for this session:

Which of the following answers BEST describes how the estimation session should proceed?

• A. The final estimate of the user story in story points is determined by applying the three-point estimation technique with the following input values most optimistic estimate - 1, most likely estimate - 3, and most pessimistic estimate - 21
• B. Memb6 and Memb4 which have produced the most pessimistic and the most optimistic estimates respectively, should explain the reasons of their choices to stimulate a discussion between all members before proceeding to another estimation round
• C. Further estimation rounds should be performed until all team members will pick the card having the same value: this value will represent the final estimate of the user story in story points.
• D. The final estimate of the user story in story points is determined by calculating the average value between the most optimistic estimate of 21 story points (Memb4> and the most pessimistic estimate of
  1 story point (Memb6)

Can "cost" be regarded as Exit criteria?

• A. Yes. Spending too much money on test ng will result in an unprofitable product, and having cost as an exit criterion helps avoid this
• B. No The cost of testing cannot be measured effectively, so it is incorrect to use cost as an exit criterion
• C. Yes. Going by cost as an exit criterion constrains the testing project which will hello achieve the desired quality level defined for the project
• D. No. The financial value of product quality cannot be estimated, so it is incorrect to use cost as an exit criterion

Which of the following statements about static testing and dynamic testing is true?

• A. Static testing is usually much less cost-effective than dynamic testing
• B. Unlike dynamic testing, which can be also performed manually, static testing cannot be performed without specialized tools
• C. Unlike dynamic testing, which focuses on detecting potential defects, static testing focuses on detecting failures which may be due to actual defects
• D. Both static testing and dynamic testing can be used to highlight issues associated with non-functional characteristics
