Chapter 2 is the smallest chapter on the CTAL-TA paper and the most expensive per question. It contributes only 3 of the 45 questions, but they are worth 7 of the 78 points, because two of the three are K4 and carry 3 points each. One answer here is worth as much as three answers in Chapter 4, which is why a chapter this short still deserves real preparation time.
The content splits cleanly in two. Risk analysis covers identification and assessment: retrospectives, risk workshops, brainstorming, checklists and stakeholder interviews as identification techniques, then the factors that drive assessment — frequency of use, criticality of features and business goals, financial and reputational damage, the quality of the test basis, and legal or safety exposure — with risks categorised against ISO/IEC 25010 (2023) and recorded in a risk register. Risk control covers mitigation and monitoring, and this is where the K4 learning objective TA-2.2.1 lives.
The examinable judgement in this chapter is test selection. The syllabus lists risk-based selection, history-based selection, coverage-based selection, requirement traceability matrices, operational profiles and impact analysis, names impact analysis as the most reliable basis for choosing automated regression tests, and is explicit that no single technique is best — you combine them and re-evaluate their effectiveness after each cycle. Expect questions that hand you a situation and ask which approach fits it, not questions that ask for a definition. The syllabus allocates 90 training minutes here; our practice pool holds 10 questions.
This chapter is covered most heavily (3 questions) in CTAL-TA — Mock Exam 1 (Test Design Techniques Deep Dive), CTAL-TA — Mock Exam 2 (Domain Partitioning, State Models & Risk-Based Test Design), CTAL-TA — Mock Exam 3 (Test Oracles, Combinatorial Design & Defect Metrics)
