Question 33
Domain 3: Applications of Foundation ModelsA team is building a multi-turn foundation model application that uses retrieved documents, chat history, and external tool results. Which task is an example of context engineering rather than prompt engineering?
Correct answer: B
Explanation
Context engineering determines what information enters the model’s context window, in what form, how much of it to include, and in what order, while prompt engineering focuses on wording a single prompt. — 50_20_Governance_and_compliance_for_AI.md §2.1.5 Context engineering in FM applications
Why each option is right or wrong
A. Rewriting the instruction so the model uses a more formal tone in a single request
Prompt engineering focuses on wording and structure of a single prompt, including tone and phrasing.
B. Choosing how many retrieved chunks to include and ordering them before sending them to the model
Section 2.1.5 defines context engineering as deciding what enters the context window, in what form, and in what order. The same section states that for retrieved documents, context engineering determines how many chunks to include and how to rank them before inference.
C. Changing a single example in the prompt to make the requested output format clearer
Prompt engineering includes how to format an example and how many examples to include in one prompt.
D. Adjusting the wording of one user query so the instruction sounds less ambiguous
Context engineering governs assembled context components such as history, retrieval, and tool outputs, not one query’s phrasing.
