Q12. Applications A and B are configured to use IBM MQ Light for Bluemix messaging capabilities. Application A publishes messages to a topic. Application B subscribes to the same topic in order to receive the messages published by Application A. What occurs when Application A publishes the message after Application B goes down? 

A. Destination stores the message and it will be received if Application B comes back up before the destination time-to-live expires. 

B. Application A receives a notification from the destination that Application B is down. 

C. Topic stores the message forever, and the message will be received by Application B after it comes back up. 

D. Destination stores the copy of the message for one hour. If Application B does not come back up within one hour the message will be lost. 

Answer:

Explanation: 

MQ Light messaging provides two models for delivery assurance, at most once, and at least once. The first is appropriate when occasional loss of data caused by a communication disruption is acceptable, and the second is required when there can be no loss of data. When using at least once, duplicate messages may appear around communication disruptions and they should to be programmatically discarded. MQ Light buffers messages based upon message and destination time-to-live. When an application subscribes to a topic it may specify a destination time-to-live, which will cause MQ Light to store messages at the destination in the event of a receiving application crash. After the destination time-to-live exipres, MQ Light will discard all held messages and stops storing new messages.
