PREPARING FOR CERTIFICATION

CHECK YOUR UNDERSTANDING • Which domains does a trace-reading skill support? ◦ Answer: Mainly the domain on measuring and understanding behavior, and also running agents and managing working memory, since traces reveal problems in all of them. • How do you tell a context problem from a tool problem in a trace? ◦ Answer: Compare what the tool actually returned with what the model was shown at the moment of the bad decision; a missing fact in the context points to context management, while a wrong tool result points to the tool. • Why should the capstone scenario you write come from real bugs you found? ◦ Answer: Real bugs make the scenario concrete and test your genuine understanding of how each layer fails. • Why can this chapter not state the passing score of the examination? ◦ Answer: Because the certifying program sets and publishes those details, and they may change, so you must read the current official requirements. APPENDICES AND REFERENCE MATERIAL • Why should you study the seven layers as a connected whole and not as separate lists? ◦ Answer: Because real problems cross layers, and a failure that appears in one layer often has its cause in another.
