ISQI ISTQB Certified Tester Foundation Level (CTFL) v4.0 Sample Questions (Q339-Q344):

NEW QUESTION # 339
Which of the following is a factor that contributes to a successful review?

Answer: D

Explanation:
A factor that contributes to a successful review is ensuring that all participants are trained to understand the review type and its objectives. This training helps participants to effectively contribute to the review process, identify issues, and suggest improvements. Proper training also fosters a constructive and collaborative review environment.


NEW QUESTION # 340
Which of the following statements is CORRECT about error guessing?

Answer: A

Explanation:
Error guessing is a testing technique where experienced testers anticipate potential defects based on their knowledge of the application and past experiences. Fault attacks, which involve focusing on areas where defects are likely to occur based on previous failures, are a practical implementation of error guessing.
References:
* ISTQB CTFL Syllabus V4.0, Section 4.4.1 on error guessing and fault attacks, explaining how testers use their experience to anticipate and target likely defects.


NEW QUESTION # 341
A new web app aims at offering a rich user experience. As a functional tester, you have run some functional tests to verify that, before releasing the app, such app works correctly on several mobile devices, all of which are listed as supported devices within the requirements specification. These tests were performed on stable and isolated test environments where you were the only user interacting with the application. All tests passed, but in some of those tests you observed the following issue: on some mobile devices only, the response time for two web pages containing images was extremely slow.
Based only on the given information, which of the following recommendation would you follow?

Answer: D

Explanation:
As a functional tester, you should open a defect report providing detailed information on which devices and by running which tests you observed the issue. A defect report is a document that records the occurrence, nature, and status of a defect detected during testing, and provides information for further investigation and resolution. A defect report should include relevant information such as the defect summary, the defect description, the defect severity, the defect priority, the defect status, the defect origin, the defect category, the defect reproduction steps, the defect screenshots, the defect attachments, etc. Opening a defect report is a good practice for any tester who finds a defect in the software system, regardless of the type or level of testing performed. The other options are not recommended, because:
The issue is related to performance efficiency, not functionality, but that does not mean that as a functional tester, you should not open any defect report as all the functional tests passed. Performance efficiency is a quality characteristic that measures how well the software system performs its functions under stated conditions, such as the response time, the resource utilization, the throughput, etc. Performance efficiency is an important aspect of the user experience, especially for web applications that run on different devices and networks. Even if the functional tests passed, meaning that the software system met the functional requirements, the performance issue observed on some devices could still affect the user satisfaction, the usability, the reliability, and the security of the software system. Therefore, as a functional tester, you have the responsibility to report the performance issue as a defect, and provide as much information as possible to help the developers or the performance testers to investigate and resolve it.


NEW QUESTION # 342
Which of the following statements about white-box testing is FALSE?

Answer: C

Explanation:
Achieving full code coverage does not guarantee that the component or system is fully tested or free of defects. Code coverage metrics indicate the extent to which the source code has been tested, but they do not account for the quality of the tests or whether all possible scenarios have been considered. Other types of testing, including functional, performance, and security testing, are necessary to ensure comprehensive testing. The ISTQB CTFL Syllabus v4.0 highlights that while high code coverage is beneficial, it does not equate to complete testing.


NEW QUESTION # 343
Use Scenario 1 "Happy Tomatoes" (from the previous question).
When running test caseTC_59, the actual result fort = 35degrees Celsius isOUTPUT = Xinstead of the expected output.
Which information should NOT be included in the defect report?

Answer: A

Explanation:
A defect report should contain relevant details to help developersreproduce and fix the defect efficiently.
The essential elements include:
* Test object & environment (A)- To ensure reproducibility.
* Title & summary (B)- For quick identification.
* Expected vs. actual results (D)- To describe the discrepancy.
Thestructure of the test team (C)is irrelevant for defect tracking and resolution.
