How are connectors handled differently in Mule 4 compared to Mule 3?

• A. Connectors are bounded to runtime
• B. Connectors are built-in
• C. Connectors are deprecated
• D. Connectors are independent extension libraries called modules

Answer: (D)

In Mule 4, connectors are handled as independent extension libraries called modules. This means connectors are decoupled from the core runtime and can be added, upgraded, or replaced without changing the Mule engine itself. Modules are packaged and distributed separately (often via Anypoint Exchange) and loaded into the runtime as needed, giving you versioned, reusable pieces of functionality that you can manage independently from the runtime. This modular approach contrasts with Mule 3, where connectors were more tightly bound to the runtime and often shipped as part of the core distribution or as tightly coupled plugins, making upgrades and maintenance less flexible. The options suggesting they’re built-in, deprecated, or strictly bound to the runtime don’t reflect Mule 4’s modular, extension-based design.
