CTFL_Syll_4.0 Exam Dumps : ISTQB Certified Tester Foundation Level (CTFL) v4.0

This answer is correct because a typical objective of testing is to ensure that a software has been tested using a combination of test techniques, such as black-box, white-box, or experience-based techniques, that are appropriate for the test objectives, test levels, and test types. Testing using a combination of test techniques can increase the effectiveness and efficiency of testing, as different techniques can target different aspects of the software quality, such as functionality, usability, performance, security, reliability, etc. Testing using a combination of test techniques can also reduce the risk of missing defects that could be detected by one technique but not by another. References: ISTQB Foundation Level Syllabus v4.0, Section 2.3.1.1, Section 2.3.2

Test execution involves running test cases and documenting results. Test logs (A) provide evidence of executed tests, failures, and actual outcomes. Automated test scripts (B) are part of test implementation, test plans (C) belong to test planning, and test conditions (D) are identified during test analysis.

Testing and debugging are separate but related activities. Testing executes the software to identify failures that result from defects (A). Debugging is the developer's responsibility and involves finding the cause of a failure (defect), analyzing it, and fixing the defect. The ISTQB syllabus explicitly differentiates these activities. Testing does not modify the software, whereas debugging does.
