Rest API - Rate Limiting and Throttling

Aif requests_user >= user_limit and requests_ip >= ip_limit: block() else: allow()

Bif requests_user < user_limit and requests_ip < ip_limit: block() else: allow()

Cif requests_user >= user_limit or requests_ip >= ip_limit: block() else: allow()

Dif requests_user <= user_limit or requests_ip <= ip_limit: block() else: allow()

Step 1: Understand the blocking condition
Requests should be blocked if either the user or IP exceeds their respective limits.
Step 2: Analyze logical operators
Using 'or' ensures blocking if any limit is reached or exceeded.
Final Answer:
if requests_user >= user_limit or requests_ip >= ip_limit: block() else: allow() -> Option C
Quick Check:
Block if user OR IP limit exceeded [OK]

Quick Trick: Use OR to combine limits for blocking [OK]
