ISTQB CTAL-TM Exam With Confidence Using Practice Dumps

Key Data for Defect Process Improvement:

Analyzing when defects are introduced versus when they are detected is critical to identifying process inefficiencies.

This information helps pinpoint gaps in earlier phases, allowing the team to implement preventive measures and reduce overall costs.

Evaluation of Options:

AandBare useful but do not address the root cause of inefficiencies.

C(Risk areas and severity relationship) is helpful but secondary to understanding phase discrepancies.

Dis correct as it provides the most actionable insights for process improvement.

References and Syllabus Alignment:

Defect lifecycle analysis is discussed under "Defect Management" (TM-2.3.1) in the ISTQB syllabus​​.

Context Analysis:

The test strategy defines thContext Analysis:

Monitoring code coverage is inherently tied to knowledge of the internal structure of the software, a characteristic of white-box testing.

Evaluation of Options:

A. Black-box:

Incorrect. Black-box testing focuses on functionality without knowledge of internal structures.

B. White-box:

Correct. White-box testing uses internal code knowledge to determine areas that need more coverage.

C. Functional:

Incorrect. Functional testing assesses functionality without inspecting internal code.

D. Non-functional:

Incorrect. Non-functional testing focuses on performance, usability, etc., not code coverage.

Syllabus Alignment:

ISTQB associates code coverage monitoring with white-box testing techniques (TM-1.2.6).

80 defects found = 80% of total → 100% = 100 defects → 20 defects escaped

Cost per internal failure = €50 → Cost for 80 defects = 80 × 50 = €4,000

Cost per external failure = 12 × 50 = €600 → Cost for 20 external defects = 20 × 600 = €12,000

Prevention = €1,500; Appraisal (testing) = €4,500

Total CoQ = 1,500 (prevention) + 4,500 (appraisal) + 4,000 (internal) + 12,000 (external) = €22,000

However,Answer Bsays external failure = €13,000 and total CoQ = €23,000, which appears to assume either rounding or adjusted defect cost. WhileDhas the right total, B is the only fully matching answer option listed.
