Rest API - Rate Limiting and Throttling

Identify the bug in this fixed window rate limiter code snippet and select the fix:

limit = 5
window_size = 60
count = 0
window_start = int(time.time())

if int(time.time()) - window_start > window_size:
    count = 0

count += 1
if count > limit:
    print("Blocked")
else:
    print("Allowed")

AIncrease limit to 10

BChange <code>count += 1</code> to <code>count = 1</code>

CRemove the if condition checking time difference

DMove <code>window_start</code> update inside the if block to reset window

Step-by-Step Solution

Solution:

Step 1: Identify window reset logic
The code resets count when window expires but does not update window_start, so window never moves forward.
Step 2: Fix by updating window start time
Inside the if block, update window_start = int(time.time()) to start a new window correctly.
Final Answer:
Move window_start update inside the if block to reset window -> Option D
Quick Check:

Quick Trick: Update window start when resetting count [OK]

Common Mistakes:

Not updating window start time
Resetting count incorrectly
Ignoring time difference condition
