Rest API - Rate Limiting and Throttling

What does the fixed window algorithm primarily control in a REST API?

AThe size of the data payload in requests

BThe number of requests allowed in a fixed time period

CThe order of API responses

DThe authentication method used

Step-by-Step Solution

Solution:

Step 1: Understand the purpose of rate limiting
Rate limiting controls how many requests a client can make in a certain time to prevent overload.
Step 2: Identify what fixed window algorithm controls
The fixed window algorithm counts requests in fixed time windows and limits the number allowed.
Final Answer:
The number of requests allowed in a fixed time period -> Option B
Quick Check:
Fixed window algorithm = Request count limit [OK]

Quick Trick: Fixed window counts requests per fixed time slot [OK]
