Answer Key and Explanations
Check these only after attempting every question.
1. B - Only to the agent whose role requires them
Least privilege limits both accidental misuse and the impact of prompt injection.
2. B - Degrade tool-selection accuracy and widen the risk surface
Choice quality falls as the option set grows, and every extra tool is extra exposure.
3. B - Retrieved context whose relevance and freshness still need checking
Attaching a knowledge source does not make the output grounded or current.
4. B - One agent's unverified assumption propagating as established fact
Memory spreads errors as efficiently as it spreads useful context.
5. B - Scoping, retention limits, and a deletion path
Agent memory is a data store and must be governed as one.
Practical Check
Apply this module to your own work: complete the module activity for *Tools, Knowledge, and Memory*, then write one sentence naming what your result shows and one naming what it does not.
Strong Answer Pattern
A strong answer names the task, the evidence used, the check performed, and the remaining limitation. It avoids "proved", "guaranteed", or "always" unless the evidence genuinely supports it.
