1. What is the primary feature that all LLM observability tools share, regardless of which one you choose?

   1. They all automatically optimize prompt token usage
   2. They all trace conversations between users and language models
   3. They all require zero code instrumentation
   4. They all provide pre-built LLM models for deployment

2. According to the key concepts covered, how do LLM observability tools primarily differentiate from one another?

   1. By whether they support closed-source or open-source models only
   2. By their evaluation capabilities, dashboards, and alerting features
   3. By whether they use cloud-based or on-premise deployment
   4. By their pricing models and per-user licensing

3. What is the recommended first step BEFORE selecting an LLM observability tool?

   1. Build your tracing schema (define your data model)
   2. Contact vendors for pricing quotes
   3. Install the most popular tool and see if it works
   4. Read all vendor documentation from cover to cover

4. Which of the following is NOT listed as a high-priority observability need in the lesson?

   1. Production debugging
   2. User authentication tracking
   3. Cost tracking
   4. Drift detection

5. What consequence does the lesson warn about when selecting the wrong LLM observability tool?

   1. Your API keys will be automatically revoked
   2. It wastes months of development time
   3. You will lose all your training data
   4. Your LLM will generate incorrect outputs

6. A developer decides to simply buy an LLM observability tool without thinking about what they need to observe. Based on the lesson, what is likely to happen?

   1. The tool will refuse to install without a requirements document
   2. They will immediately achieve production-grade monitoring
   3. They will likely have poor observability despite owning the tool
   4. The tool will automatically determine the best metrics to track

7. The lesson mentions three components of integration cost that should be planned for. Which one is NOT mentioned as part of integration cost?

   1. Data retention
   2. Prompt engineering
   3. Instrumentation
   4. Retrieval

8. The lesson emphasizes that every observability tool requires ongoing operational maintenance. Which of the following is NOT mentioned as a maintenance requirement?

   1. Instrumentation maintenance
   2. Schema evolution
   3. Dashboard updates
   4. Free weekly feature upgrades

9. Based on the lesson, what should guide your evaluation of different LLM observability tools?

   1. Generic feature lists from vendor websites
   2. Your specific ranked observability needs
   3. The cheapest option available
   4. The most popular tools on Hacker News

10. Which statement best captures the lesson's core message about LLM observability tool selection?

    1. Pick the tool with the most features regardless of your needs
    2. The best tool is whatever your team already knows how to use
    3. Tool selection should follow defining your observability requirements and data model
    4. Any observability tool will work if you have enough budget

11. The lesson notes that observability tools require 'some operational burden.' What does this imply for teams adopting these tools?

    1. They will need to hire additional AI researchers to manage it
    2. The tool will operate without any human involvement after setup
    3. They should plan for ongoing maintenance and updates
    4. They can install a tool and then ignore it indefinitely

12. A student asks: 'If I implement an LLM observability tool, will my system automatically become observable?' What does the lesson say about this assumption?

    1. No, but only if you use a premium-tier tool
    2. Yes, but only for prompt-based interactions
    3. No, you must instrument your code to get observability
    4. Yes, observability is automatic once the tool is installed

13. You are comparing LangSmith, LangFuse, and Helicone for your LLM application. Based on the lesson, what is the correct approach to making this decision?

    1. Select the tool that works with the most LLM providers
    2. Rank your observability needs first, then evaluate each tool against those needs
    3. Pick the one with the longest free trial period
    4. Choose whichever tool has the most YouTube tutorials

14. Your team needs to debug production issues where LLM responses are degraded. What approach does the lesson recommend for addressing this observability need?

    1. Hire a dedicated machine learning engineer to watch the system 24/7
    2. Wait until users report problems
    3. Implement random sampling of all requests to reduce data volume
    4. Select a tool with strong production debugging capabilities and ensure your tracing schema captures relevant metrics

15. The lesson includes 'buy vs. build vs. extend-existing-tool' as a recommended assessment. What does this assessment help determine?

    1. Which programming language to use for your application
    2. How much to charge customers for LLM services
    3. Which cloud provider to use
    4. Whether to build custom observability, purchase a tool, or extend current monitoring infrastructure
