Question 2

In the JMS API for the publish-subscribe domain, how does a durable subscriber differ from a non-durable subscriber?

B. If a topic has a durable subscriber, the JMS provider logs all messages in a persistent media so that an application can inspect the log and extract messages at a later time.

C. If a durable subscriber becomes disconnected without unsubscribing and later reconnects, the subscriber receives messages that arrived while the subscriber was not active.
