Question:
In which situation would a synchronous API be used?
- when a server is not part of the process
- when the original API request or data from the request is delayed
- when data is being retrieved from a database
- when the client is not required to take action
Explanation: Synchronous APIs respond to a request directly and immediately such as when data is being provided from memory or a database. In contrast, asynchronous APIs may send a notification that a data request has been made, send the data later, trigger a callback to provide the data, or process the request and then take an appropriate action. The action can be immediate, but it does not have to be.
