Which statement about global exception strategies is true?

• A. They cannot be invoked from within another exception strategy
• B. They are only used for batch processing
• C. They must be defined in the global scope
• D. They can be called from within another exception strategy using a reference exception strategy

Answer: (D)

Global exception strategies provide centralized, reusable error handling that can apply across multiple flows. They live in the global scope so their logic can be reused wherever needed. A key benefit is that you can invoke a global strategy from within another exception strategy by using a reference exception strategy. This lets you delegate to the same, consistent error-handling logic instead of duplicating it in every local handler, keeping behavior uniform and maintenance easier.

That’s why the statement about being able to call a global exception strategy from within another using a reference exception strategy is true. It contrasts with the idea that they can’t be invoked from within another strategy, or that they’re limited to batch processing, or that they must be defined in a strict global scope in a way that precludes reuse. The essence is reuse and centralized control of error handling through references.
