Which of the following options would allow you to perform actions only after the record trigger event?

The option that allows you to perform actions only after the record trigger event is scheduled paths. Scheduled paths enable a delay between the initial triggering of an event and when subsequent actions are carried out. This means that the actions are set to occur after certain conditions are met, which is beyond the immediate execution cycle of the initial record-triggered flow.

Scheduled paths help in scenarios where responding to a record trigger needs to wait for a specified period before executing further actions. This can be useful for actions like sending follow-up emails or updating records at a later date based on certain events that occur in the organization's processes.

While the other options do involve actions related to record triggers, they do not exclusively refer to performing actions after the event has occurred in the same manner as scheduled paths do. For instance, running actions asynchronously generally refers to actions run independently of the main transaction flow and might happen concurrently rather than strictly afterward. Fast field updates are immediate and typically occur during the same transaction. Related records and actions involve real-time execution as well. Therefore, scheduled paths are uniquely positioned to encapsulate actions that are executed strictly after the record trigger event.
