Question :-

Which statement is true about how the BPEL Process Manager works?
If the transaction property for a synchronous BPEL process is set to requiresNew transaction, a new transaction is created for the execution and the existing transaction (if there is one) is suspended.
If the transaction property for an asynchronous BPEL process is set to required, the BPEL process joins a caller's transaction (if there is no one) or creates a new transaction (if there is no transaction)
If the delivery policy for a synchronous BPEL process is set to sync, the instance-initiating message is not temporarily saved in the delivery layer.
If the delivery policy for a synchronous BPEL process is set to async.persist, messages to the system are saved in the delivery store before being picked up by the service engine.
