Step-by-Step Solution
Solution:
Step 1: Understand burst and rate limits
Burst limit allows a short spike of 50 requests instantly; rate limit allows 100 steady requests per second.Step 2: Apply limits to 120 requests
With 120 requests arriving instantly, only 50 are allowed immediately (burst); the remaining 70 exceed the burst capacity and are throttled (429 errors).Final Answer:
50 requests are allowed immediately; remaining 70 are throttled -> Option AQuick Check:
Burst limit controls instant spike = B [OK]
Quick Trick: Burst limit allows instant spike; rate limit controls steady flow [OK]
Common Mistakes:
- Assuming all requests pass instantly
- Confusing burst limit with rate limit
- Thinking requests are queued automatically
