MuleSoft Certified Platform Architect – Level 1 — Question 2

A System API is designed to retrieve data from a backend system that has scalability challenges.
What API policy can best safeguard the backend system?

Answer options

• A. IP whitelist
• B. SLA-based rate limiting
• C. OAuth 2 token enforcement
• D. Client ID enforcement

Correct answer: B

Explanation

SLA-based rate limiting is the correct choice because it helps manage and control the number of requests sent to the backend system, preventing overload. The other options, while they offer various security measures, do not specifically address the need to limit the request rate to ensure the backend can handle the load effectively.
