A customer has a Stock Watch application that publishes stock recommendations to different
customers and programs. The stock recommendation message should be processed by only
one of the JMS Servers in the cluster. Which JMS model should be used?

A. JMS Queue
B. Distributed JMS Queue
C. Uniform Distributed Topic
D. Partitioned Distributed Topic

Answer(s): A
Explanation:
JMS queue
A staging area that contains messages that have been sent and are waiting to be read. Note
that, contrary to what the name queue suggests, messages don't have to be delivered in the
order sent. A JMS queue only guarantees that each message is processed only once.

Incorrect:
Not B: (Only one queue required)
* A distributed destination is a set of destinations (queues or topics) that are accessible as a
single, logical destination to a client. A distributed destination has the following characteristics:
It is referenced by its own JNDI name.
Members of the set are usual y distributed across multiple servers within a cluster, with each
destination member belonging to a separate JMS server.

* A distributed queue is a set of physical JMS queue members. As such, a distributed queue
can be used to create a QueueSender, QueueReceiver, and a QueueBrowser. The fact that a
distributed queue represents multiple physical queues is mostly transparent to your application.

Not Topic:
JMS topic
A distribution mechanism for publishing messages that are delivered to multiple subscribers.

affinity is supported at the global transaction Id level. The new feature is called WebLogic Active
GridLink for RAC; which is implemented as the GridLink data source within WebLogic Server.
