MuleSoft Integration Foundations Intermediate Practice Exam: Medium Difficulty 2025

A retailer wants to expose an API for mobile checkout that needs to evolve over time without breaking older versions of the app. They want a contract-first approach and clear validation of request/response formats. Which approach best meets the requirement?

A logistics company must integrate an on-prem ERP with a cloud CRM. The ERP can only send outbound messages in near real time, and the CRM has strict API rate limits. The business wants reliable delivery and the ability to absorb bursts without losing messages. What is the best integration approach?

A team is designing an integration that exposes customer data to multiple consumer applications. They want to reduce coupling to the underlying systems and provide a consistent customer profile regardless of whether data comes from CRM, ERP, or a marketing platform. In an API-led connectivity approach, which API layer is the best fit for this responsibility?

A developer wants to quickly create a new Mule application using a connector to Salesforce and reuse an existing API specification already published by another team. Which MuleSoft assets and repositories best support this reuse workflow?

An organization has several APIs that must enforce client authentication, apply rate limiting, and log request metrics consistently. They want these controls applied without changing the API implementation code. Which MuleSoft capability best addresses this?

A team deployed a Mule app to CloudHub and needs to troubleshoot intermittent timeouts reported by consumers. They want centralized visibility into logs and basic operational metrics for the application without redeploying it. Which Anypoint component should they use first?

A financial services company must ensure that a payment update is processed exactly once by downstream systems. During network interruptions, the sender may retry requests. Which integration pattern best helps prevent duplicate processing while still allowing retries?

An e-commerce company needs to call three downstream services to assemble an order summary: inventory, shipping, and promotions. The response time should be minimized, and if promotions is slow, the company prefers to return the order summary without promotions rather than fail the whole request. Which design is most appropriate?

A Mule app integrates with an external API that occasionally returns transient 503 errors. The business wants the integration to automatically retry a few times, but avoid retry storms and ensure failures are handled cleanly when the downstream system is truly unavailable. What is the best approach?

A team wants to promote a Mule application from development to test to production with minimal risk. They need environment-specific values (like endpoints and credentials) to differ per environment without changing the code. Which approach best supports this goal?
