17. The implementation of a Process API must change .

What is a valid approach that minimizes the impact of this change on API clients?

Implement required changes to the Process API implementation so that whenever possible, the Process API's RAML definition remains unchanged

Update the RAML definition of the current Process API and notify API client developers by sending them links to the updated RAML definition

Postpone changes until API consumers acknowledge they are ready to migrate to a new Process API or API version

Implement the Process API changes in a new API implementation, and have the old API implementation return an HTTP status code 301 - Moved Permanently to inform API clients they should be calling the new API implementation

18. How does timeout attribute help inform design decisions while using JMS connector listening for incoming messages in an extended architecture (XA) transaction?

After the timeout is exceeded, stale JMS consumer threads are destroyed and new threads are created

The timeout specifies the time allowed to pass between receiving JMS messages on the same JMS connection and then after the timeout new JMS connection is established

The time allowed to pass between committing the transaction and the completion of the mule flow and then after the timeout flow processing triggers an error

The timeout defines the time that is allowed to pass without the transaction ending explicitly and after the timeout expires, the transaction rolls back
