1. What does a rate limit tier primarily control for an API user?

   1. The speed at which the AI model generates responses
   2. The amount of data storage you receive for free
   3. The maximum number of requests or tokens you can send within a time window
   4. The number of different API endpoints you can access

2. If a vendor lists a rate limit of '150K TPM', what does the 'M' stand for?

   1. Month
   2. Megabyte
   3. Million
   4. Minute

3. Why would a developer implement a multi-vendor API strategy?

   1. To reduce the cost of all API calls across vendors
   2. To simplify their codebase by using one SDK
   3. To hedge against a single vendor experiencing outages or hitting rate limits
   4. To automatically switch to the cheapest vendor for each request

4. A developer notices their app hits rate limit errors consistently at 2 PM each day. However, their average requests per minute stays well below the limit. What's the most likely cause?

   1. The vendor's servers are down
   2. The AI model is running slower than usual
   3. The API's authentication token expired
   4. Per-minute averages are masking second-level burst caps

5. What typically happens when you exceed your rate limit?

   1. Your account is automatically upgraded to the next tier
   2. Your API bill is automatically doubled
   3. Requests are queued and processed later
   4. The API returns error responses and may block further requests

6. What does RPM stand for in the context of API rate limits?

   1. Requests Per Minute
   2. Response Payload Maximum
   3. Resource Per Million
   4. Rate Processing Module

7. A startup is growing at 20% month-over-month. They currently use 80% of their tier's TPM limit. When should they start planning for a tier upgrade?

   1. Only after their enterprise contract negotiation
   2. When competitors start using the same tier
   3. When they hit exactly 100% of the limit
   4. Immediately—they'll exhaust their current tier within 1-2 months

8. What is a recommended mitigation step when you anticipate hitting rate limits?

   1. Permanently lower your API usage to zero
   2. Implement request queuing and retry logic with exponential backoff
   3. Switch to a competitor's entirely different technology
   4. Delete your API logs to reduce overhead

9. Why is testing under real spike patterns important, not just using averages?

   1. Averages tell you exactly when the AI will crash
   2. Real spikes use less API credits than synthetic tests
   3. Spikes can exceed burst caps that averages don't reveal
   4. The AI responds faster during spike tests

10. Which vendor-specific detail should you track to plan capacity?

    1. The vendor's employee headcount
    2. The vendor's marketing budget
    3. The vendor's tier progression criteria and upgrade requirements
    4. The vendor's stock price history

11. What happens when you negotiate custom rate limits?

    1. They require an enterprise contract and negotiation
    2. They apply retroactively to past usage
    3. They become available automatically to all users
    4. They guarantee unlimited requests at a fixed price

12. If Vendor A offers 100K TPM and Vendor B offers 50K TPM, what is the combined capacity if you use both?

    1. 150K TPM (sum of both vendors)
    2. 50K TPM (limited by the smaller vendor)
    3. 100K TPM (limited by the larger vendor)
    4. 200K TPM (doubled capacity)

13. What does capacity planning help you avoid?

    1. Writing code comments
    2. Paying taxes on API usage
    3. Unexpected service disruptions from hitting rate limits
    4. Choosing the wrong programming language

14. Which statement about tier upgrade timing is correct?

    1. Vendors publish exact dates for when your tier will upgrade
    2. Tier upgrades happen automatically every six months
    3. The exact timing of tier upgrades cannot be precisely predicted
    4. Upgrades are based on calendar quarters only

15. What is the relationship between rate limit tiers and what you can ship?

    1. Higher tiers allow more features and higher-traffic products to be launched
    2. Tiers determine which programming languages you can use
    3. Rate limit tiers have no impact on product features
    4. Tiers only affect pricing, not product capability
