CTAL-TM Exam Dumps : Certified Tester Advanced Level Test Management (CTAL-TM) v3.0

Understanding the Defect Trend Gap:

A gap between "defects opened" and "defects closed" usually indicates defects that have been resolved (fixed) but are pending formal closure, often awaiting retesting or approval.

The trend convergence suggests the defect management process is effective, but some defects are still in the verification stage.

Evaluation of Options:

Ais incorrect: The gap does not indicate projected but unfound defects.

Cis incorrect: Regression defects would cause a divergence, not convergence, in trends.

Dis incorrect: Defects introduced to production are unrelated to the convergence.

Bis correct as it aligns with the standard defect lifecycle.

References and Syllabus Alignment:

This aligns with "Defect Management" in the ISTQB syllabus, emphasizing defect lifecycle tracking (TM-2.3.1)​​​.

Context Analysis:

Heavyweight risk-based techniques involve thorough, detailed analyses to identify and mitigate potential risks comprehensively.

Hazard analysis is a structured method to identify and address risks, commonly used in safety-critical domains.

Evaluation of Options:

A. Systematic software testing:

Incorrect. While methodical, it is not inherently a risk-based technique.

B. Pragmatic risk analysis:

Incorrect. This is a lightweight technique emphasizing practical application over detailed analysis.

C. Brainstorming:

Incorrect. While useful for generating ideas, it is not detailed enough to qualify as heavyweight.

D. Hazard analysis:

Correct. It is a formal and comprehensive approach, qualifying as a heavyweight technique.

Syllabus Alignment:

ISTQB highlights hazard analysis as a detailed, structured risk-based technique (TM-1.3.4).

Estimation Technique Selection:

Extrapolation uses historical data from similar projects to estimate effort for a new one.

Since the current upgrade is 10% larger than the previous one, extrapolation is the most straightforward method.

Evaluation of Options:

A(Function points) focuses on size estimation and is not specific to historical data.

C(Planning poker) andD(Three-point estimation) involve collaborative or probabilistic techniques, not a direct extrapolation.

Bis correct as it directly applies historical project data to estimate effort.

References and Syllabus Alignment:

Effort estimation techniques are covered under "Test Estimation" (TM-2.2.1) in the syllabus​​.
