1. In a LlamaIndex router query engine system, what does it mean for the router to 'dispatch' a question?

   1. The router splits the question into multiple smaller sub-questions
   2. The router translates the question into a different programming language
   3. The router sends the question to the most appropriate specialized engine for processing
   4. The router stores the question in a database for later retrieval

2. Which of the following is a task that AI can perform effectively when building a LlamaIndex router query engine?

   1. Deciding which specialized engines should be included in the inventory
   2. Choosing the final production deployment strategy for the system
   3. Generating evaluation cases that test boundary conditions between different engines
   4. Determining the business logic for when each engine should be used

3. A routing rubric in a LlamaIndex router system serves which primary purpose?

   1. It documents the code structure for implementing the router
   2. It provides a backup list of engines to use when the primary engine fails
   3. It specifies how to log routing decisions for compliance
   4. It defines the criteria for mapping different types of questions to appropriate engines

4. Why is logging every routing decision considered a critical practice for LlamaIndex routers?

   1. Without logs, the router cannot function due to memory limitations
   2. Routers can make incorrect selections without raising obvious error messages
   3. The logs are required by government data protection regulations
   4. Logged decisions train the router to improve over time automatically

5. What aspect of a router query engine system requires human decision-making that AI cannot automate?

   1. Generating the code that implements the router logic
   2. Determining which specialized engines belong in the application's engine inventory
   3. Translating the routing rubric into executable code
   4. Creating test questions to evaluate routing accuracy

6. According to the concepts covered, what is the primary reason human curation of routing decisions cannot be replaced by AI?

   1. AI lacks contextual knowledge about whether a routing choice served the user's actual needs
   2. Human curation is required only for the initial setup, not ongoing operation
   3. AI systems are prohibited from accessing routing logs for legal reasons
   4. AI cannot distinguish between correct and incorrect routing code

7. What is a fallback path in a LlamaIndex router query engine?

   1. An alternative route taken when no primary engine is confidently selected for a question
   2. A debugging mode that reveals the internal routing logic to administrators
   3. A reserve engine that handles all questions during system maintenance
   4. A secondary network connection used when the primary server goes down

8. If a router selects an inappropriate engine but returns a valid-looking response, why might this problem go undetected without review?

   1. The system does not flag the routing decision as an error since a response was generated
   2. Users typically cannot tell which engine handled their question
   3. The incorrect engine will automatically correct itself on the next request
   4. The router logs will show the correct engine was selected regardless of actual performance

9. What does the lesson mean by saying the 'tool inventory' is an application-design decision?

   1. Tool inventory decisions must be approved by a formal design committee
   2. The inventory can be automatically determined by analyzing user queries
   3. All applications should use the same standard set of tools provided by LlamaIndex
   4. The specific set of specialized engines needed depends on the particular use case and requirements of the application

10. Which of the following would be the most appropriate action to take after a weekly review of router logging data reveals a 5% error rate in routing decisions?

    1. Replace the entire router system with a different query engine
    2. Deploy additional engines to handle the misrouted question types
    3. Disable logging to reduce system overhead since errors are now known
    4. Analyze the misrouted questions to identify patterns and refine the routing rubric

11. When the lesson states that AI can 'scaffold' a router query engine, what does this imply about AI's role?

    1. AI can provide a starting framework or structure that humans then customize and refine
    2. AI can create the complete documentation needed for regulatory compliance
    3. AI can replace human developers entirely in the development process
    4. AI can fully build and deploy a production-ready router system without human involvement

12. What distinguishes a well-designed engine inventory from a poorly designed one?

    1. The inventory includes engines that cover distinct, non-overlapping capabilities relevant to the application's needs
    2. The inventory contains the maximum possible number of available engines
    3. The inventory uses only open-source engines rather than commercial ones
    4. The inventory is chosen entirely by AI without human input

13. Why might AI struggle to decide which engines belong in a router's inventory for a customer support application?

    1. AI has too much knowledge about support systems and becomes overwhelmed by options
    2. AI cannot read documentation about the available engines
    3. AI only understands technical specifications, not business requirements
    4. AI lacks understanding of the specific types of support queries the business receives and needs to handle

14. What relationship does the routing rubric establish between questions and engines?

    1. It replaces the need for multiple specialized engines with a single universal engine
    2. It ranks engines in order of preference for all possible questions
    3. It maps characteristics of questions to the engine best suited to handle each category
    4. It determines which questions should be rejected rather than processed

15. If a new type of user question emerges that doesn't fit any existing engine's specialty, what should the routing system do?

    1. Reject the question and ask the user to reformulate it
    2. Route the question to all available engines simultaneously
    3. Automatically create a new engine to handle the novel question type
    4. Use the fallback path to attempt an appropriate response rather than failing completely
