II. Một vài câu hỏi và gợi ý cho Sample Exam
Question #1 (1 Point) Which of the following statements describe a valid test objective?
a) To prove that there are no unfixed defects in the system under test
b) To prove that there will be no failures after the implementation of the system into production
c) To reduce the risk level of the test object and to build confidence in the quality level
d) To verify that there are no untested combinations of inputs
Select ONE option.
**Gợi ý: **
Key: Valid test objective: A reason or purpose for designing and executing a test.
Đáp án: c) To reduce the risk level of the test object and to build confidence in the quality level
a) Incorrect. Vì không thể chứng minh no unfixed defects trong hệ thống khi được kiểm thử
b) Incorrect. Sai so với 7 nguyên tắc kiểm thử
d) Incorrect. Không thể kiểm tra tất cả các kết hợp đầu vào
Question #2 (1 Point) Which of the following options shows an example of test activities that contribute to success?
a) Having testers involved during various software development lifecycle (SDLC) activities will help to detect defects in work products
b) Testers try not to disturb the developers while coding, so that the developers write better code
c) Testers collaborating with end users help to improve the quality of defect reports during component integration and system testing
d) Certified testers will design much better test cases than non-certified testers
Select ONE option.
**Gợi ý: **
Đáp án: a) Having testers involved during various software development lifecycle (SDLC) activities will help to detect defects in work products
b) Incorrect. Vì developers và testers sẽ có nhiều hiểu biết về sản phẩm công việc của nhau và cách kiểm tra code
c) Incorrect. End users sẽ không giúp sẽ không giúp testers nâng cao chất lượng của các báo cáo bug/defects; Ngoài ra, End users thường không tham gia vào các hoạt động cấp thấp các cấp độ kiểm tra như kiểm tra tích hợp
d) Incorrect. Được chứng nhận không có nghĩa là người thử nghiệm sẽ thiết kế testcase tốt hơn. Việc thiết kế testcase phụ thuộc vào skill và kinh nghiệm trong công việc của mỗi cá nhân
Question #3 (1 Point) You have been assigned as a tester to a team producing a new system incrementally. You have noticed that no changes have been made to the existing regression test cases for several iterations and no new regression defects were identified. Your manager is happy, but you are not. Which testing principle explains your skepticism?
a) Tests wear out
b) Absence-of-errors fallacy
c) Defects cluster together
d) Exhaustive testing is impossible
Select ONE option.
**Gợi ý: **
Đáp án: a) Tests wear out. Bởi vì Nguyên tắc này có nghĩa là nếu các bài kiểm tra tương tự được lặp lại nhiều lần và lặp đi lặp lại, cuối cùng những thử nghiệm này không còn tìm thấy bất kỳ khiếm khuyết mới nào nữa. Đây có lẽ là lý do tại sao tất cả các bài kiểm tra đều vượt qua trong phiên bản này.
Question #4 (1 Point) You work in a team that develops a mobile application for food ordering. In the current iteration the team decided to implement the payment functionality. Which of the following activities is a part of test analysis?
a) Estimating that testing the integration with the payment service will take 8 person-days
b) Deciding that the team should test if it is possible to properly share payment between many users
c) Using boundary value analysis (BVA) to derive the test data for the test cases that check the correct payment processing for the minimum allowed amount to be paid
d) Analyzing the discrepancy between the actual result and expected result after executing a test case that checks the process of payment with a credit card, and reporting a defect
Select ONE option.
**Gợi ý: **
Đáp án: b) Deciding that the team should test if it is possible to properly share payment between many users.
Question #5 (1 Point) Which of the following factors (i-v) have SIGNIFICANT influence on the test process?
i. The SDLC
ii. The number of defects detected in previous projects
iii. The identified product risks
iv. New regulatory requirements forcing formal white-box testing
v. The test environment setup
a) i, ii have significant influence
b) i, iii, iv have significant influence
c) ii, iv, v have significant influence
d) iii, v have significant influence
Select ONE option.
**Gợi ý: **
Đáp án: b) i, iii, iv have significant influence - ( The SDLC, The identified product risks, New regulatory requirements forcing formal white-box testing)
Question #6 (1 Point) Which TWO of the following tasks belong MAINLY to a testing role?

**Gợi ý: **
Đáp án: a) Configure test environments và e) Report on achieved coverage.
Bởi vì b) Maintain the product backlog được làm bởi product owner, c) Design solutions to new requirements được làm bởi dev, d) Create the test plan được làm bởi a managerial role
Question #7 (1 Point) Which of the following skills (i-v) are the MOST important skills of a tester?

ii. Creating a product vision
iii. Being a good team player
iv. Planning and organizing the work of the team
v. Critical thinking
a) ii and iv are important
b) i, iii and v are important
c) i, ii and v are important
d) iii and iv are important
Select ONE option
**Gợi ý: **
Đáp án: b) i, iii and v are important - (Having domain knowledge, Being a good team player, Critical thinking )
Question #8 (1 Point) How is the whole team approach present in the interactions between testers and business representatives?
a) Business representatives decide on test automation approaches
b) Testers help business representatives to define test strategy
c) Business representatives are not part of the whole team approach
d) Testers help business representatives to create suitable acceptance tests
Select ONE option.
**Gợi ý: **
Đáp án: d) Testers help business representatives to create suitable acceptance tests. Vì tester sẽ làm việc chặt chẽ với đại diện doanh nghiệp để đảm bảo đạt được mức chất lượng mong muốn. Điêu nay bao gồm hỗ trợ và cộng tác với họ để giúp họ tạo ra những Acceptance testing
