質問 3：
A customer information lookup service works in the following manner:
The client application makes a request to the server using the customerID. The server application subscribes to this requests, looks up the customer record in a database and returns the complete customer record to the initiating client.
What would be the most efficient subject name usage for this service?
A. The client application creates an inbox listenerand publishes a message on the lookup subject with it inbox name in the eply message field and the customerID in the custid message field. The server application subscribes to lookup and publishes its reply on the subject contained in the eply message field.
B. The client application creates an inbox listenerand publishes a message on the lookup.customerID subject with it inbox name in the eply message field. The server application subscribes to lookup.*, gets the customerID from the subject name field of the messages it receives and publishes its reply on the subject contained in the eply message field.
C. The client application creates a listener on thelookup.reply.customerID subject and publishes a message on the lookup.request subject with the customerID in the custid message field. The server application subscribes to ookup.request and publishes its reply on lookup.reply.customerID.
D. The client application creates an inbox listenerand publishes a message on the lookup.<_INBOX> subject with it inbox name as the second part of the subject and the customerID in the ustid message field. The server application subscribes to lookup.* and publishes its reply on the subject contained in the second part of the subject.
