What occurs during the execution of record-triggered flows that run asynchronously?

During the execution of record-triggered flows that run asynchronously, these flows are processed after the main flow completes. This means that once the primary operations associated with the record trigger have been finalized, the asynchronous flows are queued and executed separately. This approach helps in managing system resources efficiently and ensures that the primary transaction does not experience delays due to the processing of additional business logic encapsulated in the flow.

Choosing this option aligns with how Salesforce handles asynchronous processes, allowing other transactions or actions to complete first, thereby ensuring a smoother user experience. The design fosters a more efficient processing environment by decoupling the flows from immediate transactional processing, which is critical in larger systems where performance and scalability are necessary.

The other options don't accurately describe the nature of asynchronous flows. For instance, preventing a record from saving implies immediate processing, which contradicts the asynchronous nature. Similarly, claiming that they occur simultaneously with updates or that they do not allow for complex logic overlooks the capabilities of record-triggered flows that can indeed handle complex logic and operate independently in the background.
