1. When selecting an AI agent runtime, which four criteria should you evaluate?

   1. Deployment complexity, scaling options, monitoring tools, and API stability
   2. Speed, cost, security, and support quality
   3. Cold-start performance, durable state management, observability features, and exit cost
   4. Latency, throughput, pricing, and documentation

2. Which of the following is a capability that AI handles well in agent runtimes?

   1. Replacing your application logic with AI-generated code
   2. Guaranteeing your agent will work the same way forever
   3. Predicting which vendor will pivot next year
   4. Handling long-running steps without timeouts

3. What does 'durability' mean in the context of AI agent runtimes?

   1. How quickly the runtime starts from a cold state
   2. The maximum number of concurrent users
   3. The ability to persist state across crashes and restarts
   4. The cost of terminating your subscription

4. A developer wants to run an agent task that takes 45 minutes to complete. Which runtime characteristic is most important to verify first?

   1. Multi-region support
   2. Max step duration
   3. Exit cost
   4. Billing model

5. What does 'exit cost' refer to when evaluating agent runtime platforms?

   1. The financial penalty for exceeding rate limits
   2. The price charged when an agent task terminates
   3. How easily you can leave the platform and take your code elsewhere
   4. The cost of deploying to production

6. Why does the lesson recommend pinning hosted-agent SDK versions?

   1. Because AI guarantees older versions work forever
   2. Because SDKs change shape often and upgrades can break your code
   3. Because pinned versions are always faster
   4. Because unpinned versions cost more money

7. What does 'observability' refer to in agent runtime platforms?

   1. The ability to monitor, trace, and debug agent execution
   2. The total number of agents running simultaneously
   3. The physical location of data centers
   4. How quickly new agents can be provisioned

8. A startup needs to run many agents, each isolated for different customers. Which AI capability from the lesson matches this need?

   1. Guarantee zero downtime
   2. Replace application logic automatically
   3. Handle long-running steps without timeouts
   4. Scale per-tenant

9. What is the relationship between cold-start performance and an agent runtime?

   1. It describes the time needed to exit the platform
   2. It measures how fast the runtime shuts down
   3. It measures how quickly the runtime can begin processing a request after being idle
   4. It refers to the speed of cooling down overloaded servers

10. The lesson mentions that hosted-agent SDKs change shape often. What should developers do before upgrading?

    1. Delete the old version first to avoid conflicts
    2. Pin the version and read release notes before upgrading
    3. Upgrade immediately to get the latest features
    4. Always wait at least two years before updating

11. What type of information do 'traces' provide in an agent runtime?

    1. Billing invoices and usage reports
    2. Detailed records of agent execution flow and decisions
    3. Customer feedback and ratings
    4. Marketing materials about the platform

12. Why is 'multi-region' support important for some agent deployments?

    1. It guarantees your agent will never crash
    2. It reduces costs by consolidating all servers in one location
    3. It allows deploying closer to users for lower latency and data sovereignty
    4. It makes exit costs lower

13. When the lesson says to 'score against your top 3 traffic patterns,' what does it mean?

    1. Estimate your marketing reach
    2. Rate the visual appearance of the dashboard
    3. Count the number of visitors to your website
    4. Give each runtime a numerical grade based on how well it handles your actual usage

14. What is a fundamental difference between what AI can do and what application logic must do in agent systems?

    1. AI and application logic are the same thing
    2. AI can write all necessary application logic automatically
    3. Application logic is optional in agent systems
    4. Application logic must be written by developers; AI cannot replace it

15. What does the lesson identify as a risk of building on hosted-agent platforms?

    1. Platforms never change their APIs
    2. The platforms are always free to use
    3. Vendors may pivot, changing their offerings
    4. AI will always maintain backward compatibility
