Which statement best describes a choice exception strategy?

Which statement best describes a choice exception strategy?

• A. Must contain two or more catch and/or rollback strategies; each catch specifies a condition; the message is routed to the first strategy whose condition evaluates to true; if none can handle the error, it is routed to the default exception strategy
• B. Must contain exactly one catch strategy
• C. Cannot reference the default exception strategy
• D. Always routes to the global exception strategy

Answer: (A)

A Choice Exception Strategy works by presenting several conditional handlers for exceptions. It includes multiple catch blocks, each with a condition. When an error occurs, Mule evaluates these conditions in order and routes the message to the first catch whose condition is true. If none match, the error goes to the default exception strategy. This setup explains why the best description is to have two or more catches with their own conditions and a fallback to the default when nothing matches. It’s not limited to a single catch, nor does it prohibit referencing a default path, and it doesn’t force routing exclusively to a global strategy—the local default serves as the final fallback.
