1. Which of the following is an example of 'doc drift' in API development?

   1. A new API endpoint is deployed to production but the online documentation still describes the old URL path
   2. The database migration changes the underlying data storage method
   3. The development team holds a meeting to discuss the API's future roadmap
   4. The API returns JSON responses but the client application expects XML format

2. An AI tool analyzing an API handler finds that a parameter exists in the source code but is missing from the documentation. What type of mismatch is this?

   1. A signature integrity failure
   2. A missing parameter documentation gap
   3. A type mismatch in the response shape
   4. A behavioral drift issue

3. Which task is AI WELL SUITED to perform in the API documentation workflow?

   1. Generating minimal markdown patches to align docs with code changes
   2. Deciding whether the code or the documentation should be considered the authoritative source
   3. Catching behavioral drift that only manifests at runtime
   4. Knowing the original intent behind an undocumented optional parameter

4. What does it mean for an AI-generated patch to 'preserve doc voice'?

   1. The patch removes all technical jargon from the documentation
   2. The patch adds artificial personality to match AI-generated content
   3. The patch maintains the original writing style and tone of the documentation
   4. The patch converts the documentation into code comments

5. A type mismatch detected by AI would most likely involve:

   1. A missing endpoint in the documentation index
   2. The docs describing a field as an integer when the code actually returns a string
   3. A change in the API's authentication method
   4. The documentation using a different font than the code editor

6. Which scenario represents 'behavioral drift' that AI cannot detect from signatures alone?

   1. An endpoint returns a 200 status code for one user and 403 for another due to a logic bug
   2. A required parameter is marked as optional in the docs
   3. A parameter is documented but not implemented in the code
   4. The documentation describes a boolean field that the code returns as a string

7. What is the primary benefit of having AI propose 'minimal' patches rather than rewriting entire documents?

   1. Minimal patches automatically test the code
   2. Minimal patches look more like AI-generated content
   3. Minimal patches are faster to generate than full rewrites
   4. Minimal patches reduce the risk of introducing new errors and preserve human editing

8. In the context of API documentation, what is OpenAPI?

   1. A tool that executes API calls automatically
   2. A specification format for describing REST APIs
   3. An AI model that writes documentation
   4. A programming language for building APIs

9. An AI comparing an API handler to its documentation finds that the docs say a field returns an 'array' but the code returns a 'dictionary object'. What kind of mismatch is this?

   1. An authentication mismatch
   2. A type mismatch in the response shape
   3. A behavioral drift issue
   4. A missing documentation gap

10. What information does the lesson say AI CANNOT determine about undocumented parameters?

    1. Whether the parameter exists in the code
    2. The parameter's data type
    3. The parameter's name
    4. The original intent behind adding the parameter

11. A developer runs an AI tool that compares a handler's source code to its documentation page. What is the primary output this tool should produce?

    1. A ranking of the developer's coding skills
    2. A list of mismatches with proposed markdown patches
    3. A decision about which API endpoints to delete
    4. A new complete rewrite of the documentation

12. Why might an API documentation team choose to use AI tools for keeping docs in sync?

    1. Because AI eliminates the need for any human involvement
    2. Because AI can guarantee the code is bug-free
    3. Because AI can automatically deploy new server infrastructure
    4. Because AI can catch discrepancies that humans might miss during manual reviews

13. An LLM is asked to create a patch for documentation that has three mismatches with the code. If the patch is truly 'minimal', what should it contain?

    1. A list of questions for the developer to answer
    2. Edits addressing only the three identified mismatches
    3. A complete rewrite of the entire documentation page
    4. Suggestions for entirely new API endpoints

14. What is the main premise of using AI to keep internal API documentation synchronized with code?

    1. AI should analyze code and documentation pairs to flag mismatches and propose fixes
    2. AI should rewrite all documentation from scratch every week
    3. AI should replace human developers entirely
    4. AI should only work with OpenAPI specifications, not code

15. Which captures a genuine tradeoff to weigh when applying these ideas?

    1. There is never any tradeoff between speed and learning.
    2. Speed and convenience can come at the cost of depth, ownership, or skill-building.
    3. Speed always damages a project beyond repair.
    4. Convenience and depth are guaranteed to grow together.
