MuleSoft Certified Platform Architect – Level 1 — Question 3

What is the most performant out-of-the-box solution in Anypoint Platform to track transaction state in an asynchronously executing long-running process implemented as a Mule application deployed to multiple CloudHub workers?

Answer options

• A. Redis distributed cache
• B. java.util.WeakHashMap
• C. Persistent Object Store
• D. File-based storage

Correct answer: C

Explanation

The Persistent Object Store is designed to handle transactions in a reliable manner, making it ideal for long-running processes that require state tracking across multiple workers. Redis distributed cache, while fast, is not specifically tailored for transaction state management in Mule applications. java.util.WeakHashMap and File-based storage do not provide the necessary durability and performance needed for asynchronous processing in this context.
