What is the main function of the Comm Daemon in outgoing message flow?

The main function of the Comm Daemon in the outgoing message flow is to read instructions and send messages out of Epic. This process is crucial because the Comm Daemon acts as the interface between Epic and external systems, ensuring that messages generated within the Epic environment are properly dispatched to their intended destinations.

The Daemon does this by interpreting the messages that need to be sent, managing their delivery according to specified protocols, and making sure that the data reaches external recipients or services without issues. This function is essential for maintaining seamless communication between Epic and other systems, enabling clinical and administrative workflows that depend on timely updates and data sharing.

The other options describe functions that do not align with the primary role of the Comm Daemon in this context. For instance, listening for incoming messages pertains more to a receiving component than to outgoing flow. Validating messages is an important step in ensuring data integrity but is typically handled before the message is sent. Retrieving messages from the Data Queue is a separate process related to message intake rather than the outgoing transmission aspect managed by the Comm Daemon.
