Which sequence of stated in the answer choices is correct in accordance with the following figure depicting the life-cycle of a defect?

1. A. S0->S1->S2->S3->S5->S1
2. B. S0->S1->S2->S3->S5->S1->S2->S3
3. C. S0->S1->S2~>S3->S4
4. D. S0->S1 ->S2->S3->S5->S3->S4

Correct Answer: D
According to the ISTQB Certified Tester Foundation Level (CTFL) v4.0, the life cycle of a defect typically follows a sequence from its discovery to its closure. In the provided figure, it starts with S0 (New), moves to S1 (Assigned), then to S2 (Resolved), followed by S3 (Verified). If the defect is not fixed, it can be Re-opened (S5) and goes back for verification (S3). Once verified, it is Closed (S4).

Which of the following exemplifies how a software bug can cause harm to a company?

1. A. "Print" prints the last page twice for a file with 1000 pages
2. B. The timeout on the login page of a web site is 9 minutes, while the requirement was for10 minutes
3. C. When uninstalling the application, the uninstall dialog has a spelling mistake
4. D. When calculating the final price in a shopping list, the price of the last item is not added

Correct Answer: D
A software bug can cause harm to a company by directly affecting its operations, reputation, user satisfaction, and financials. Option D, "When calculating the final price in a shopping list, the price of the last item is not added," describes a defect that directly impacts the core functionality of a financial transaction, potentially leading to financial loss and customer dissatisfaction. This can have severe implications for the company's credibility and revenue. Options A, B, and C describe bugs that, while potentially annoying, do not have the same direct impact on the company's core operations and financial integrity as option D.

Which of the following is correct with regards to debugging?

1. A. Debugging identifies the cause of a failure
2. B. Debugging is often performed by test engineers
3. C. Debugging is considered part of the testing activities
4. D. Debugging is intended to find as many defects as possible in the code

Correct Answer: A
Debugging is the process of finding, analyzing and removing the causes of failures in software. Debugging is not considered part of testing, but rather a development activity that can involve testing. Debugging is not intended to find as many defects as possible, but rather to fix the specific failure that was observed. Debugging is usually performed by developers, not by test engineers.

Which of the following is the BEST reason for selecting a particular type of software development lifecycle model?

1. A. The project manager's preference
2. B. Tester skill level with the software development lifecycle model
3. C. The project team's overall familiarity with the model
4. D. The type of product being developed

Correct Answer: D
The choice of a software development lifecycle (SDLC) model is primarily influenced by the type of product being developed. Different products and project requirements may demand different SDLC models to address specific challenges and needs efficiently. For instance, a complex, safety-critical product might best be served by a Waterfall model due to its structured nature and phase dependencies, while a more iterative and incremental model might be suited for projects requiring frequent feedback and changes.References:ISTQB Certified Tester Foundation Level Syllabus v4.0, Section 2.1 "Software Development Lifecycles".

Given the following review types and review characteristics:
* a. Pair review
* b. Walkthrough
* c. Technical review
* d. Inspection
* 1. Formal
* 2. Informal
* 3. Purposes include evaluating the quality of the work product under review and generating new ideas (e.g., brainstorming solutions)
* 4. Purposes include Improving the software product and training the review participants Which of the following BEST matches the review type with the review characteristic?

1. A. a-1. b-4, c-3. d-2
2. B. a-4, b-3. c-2. d-1
3. C. a-2, b-3, c-4, d-1
4. D. a-2, b-4, c-3. d-1

Correct Answer: C
Pair reviews are informal and typically involve two people reviewing the work product together, often in an informal setting. Walkthroughs are more formal and aim to educate stakeholders and evaluate the product, serving the dual purpose of improving the product and training participants. Technical reviews have a strong focus on improving the product's quality, often involving technical stakeholders. Inspections are the most formal review type and are aimed primarily at detecting defects.References:ISTQB Certified Tester Foundation Level Syllabus v4.0, Section 3.2.3 "Review Types".
