1. Which type of error is most appropriate for implementing a retry mechanism?

   1. Errors that require manual human intervention to fix
   2. Errors that indicate the server is permanently shut down
   3. Errors that indicate the request was malformed and will always fail
   4. Errors that occur intermittently and often resolve on their own

2. A payment API is called but times out. Without an idempotency key, what is the risk of retrying the payment?

   1. The merchant might not receive the payment at all
   2. The payment could be refunded automatically
   3. The payment might be processed at a higher amount
   4. The customer could be billed multiple times for the same purchase

3. What is the primary purpose of adding jitter to a backoff strategy?

   1. To make the retry attempts happen faster
   2. To ensure all retry attempts fail quickly
   3. To prevent multiple agents from retrying at exactly the same moments
   4. To log exactly when each retry occurs

4. A service experiences a prolonged outage affecting all users. Which strategy handles this better than retries alone?

   1. Adding more retry attempts
   2. Using longer wait times between retries
   3. Trying the request with different parameters
   4. Implementing a circuit breaker that stops calling the failing service

5. What does it mean for a system to be 'fail-closed' regarding retries?

   1. The system automatically fixes itself without any intervention
   2. The system continues retrying even when it should probably give up
   3. The system stops retrying and returns an error immediately
   4. The system ignores all errors and continues normal operation

6. An AI agent is building a retry policy for a new API. What can AI reliably help determine?

   1. The exact business impact of a failed operation
   2. Whether the specific API requires an idempotency key
   3. Which HTTP status codes indicate transient versus permanent errors
   4. Whether the API is currently experiencing an outage

7. What specific information does an idempotency key provide to an API?

   1. The timestamp of when the request was made
   2. The user's authentication credentials
   3. A unique identifier that ensures duplicate requests are recognized and ignored
   4. The priority level of the request

8. Why should agents implement a maximum retry limit rather than retrying indefinitely?

   1. To make the agent's behavior more predictable to users
   2. To prevent wasting resources on requests that will never succeed and to identify real failures
   3. To save money on API costs that accumulate with each retry
   4. To ensure the agent always completes its task within a certain time

9. What is a 'retry storm' and why is it problematic?

   1. A method for testing retry logic
   2. Many agents retrying simultaneously and overwhelming a recovering service
   3. A single retry that takes too long to complete
   4. A type of error that cannot be recovered from

10. Which of the following best describes why AI cannot fully replace circuit breakers?

    1. AI lacks visibility into system-wide failure patterns across many services
    2. AI always prefers to retry rather than give up
    3. AI makes circuit breakers run too slowly
    4. Circuit breakers require real-time failure counting that AI cannot perform

11. A developer is designing a tool that calls an external weather API. What should they verify before implementing retry logic?

    1. Whether the weather API is free or paid
    2. The weather API's marketing budget
    3. The exact latitude and longitude of the weather API server
    4. Whether the API supports idempotent requests for the operation being performed

12. What is a transient error?

    1. An error that occurs once and never happens again
    2. An error that only affects certain types of users
    3. An error that permanently breaks the system
    4. An error that is temporary and may resolve on its own

13. What does it mean to 'give up' in the context of retry strategies?

    1. Automatically switching to a different API provider
    2. Exhausting the maximum number of retry attempts and moving to error handling
    3. Permanently disabling the agent
    4. Stopping all agent operations entirely

14. What is a limitation of AI in determining retry policies?

    1. AI cannot calculate wait times between retries
    2. AI cannot count to three
    3. AI cannot access the actual API documentation or guarantee that specific APIs are safe to retry
    4. AI cannot distinguish between successful and failed requests

15. When designing a retry policy, which of these elements should be explicitly defined?

    1. The user's email address
    2. Which error types warrant retries, maximum attempts, backoff timing, and fallback behavior
    3. The color scheme of error messages
    4. The physical location of the server
