If a service consumer program needs to get data from a service that is not available, it can poll the service by periodically issuing a request message. This type of interaction can be inefficient because it can lead to unnecessary message transmissions.
Which of the following statements describes a solution to this problem?

  1. By applying the Messaging Metadata pattern, the service consumer can write a request identifier in the message header. Service agents then intercept the request messages and do not forward those that contain a previously detected identifier. This practice eliminates the delivery of the duplicate messages to the service.
  2. The Event-Driven Messaging pattern can be applied to establish a messaging framework in which service consumers are automatically notified of relevant runtime service events.
  3. By applying the Atomic Service Transaction pattern, a service can be designed to invoke an alternative exception handling process when it is unavailable to receive a given message.
  4. None of the these statements describe solutions that directly solve this problem.

Answer(s): B



Which of the following statements about the subscriber role established by the application of the Event-Driven Messaging pattern is true?

  1. a service can have multiple consumers as subscribers
  2. a consumer can only subscribe to one service
  3. a service can only have one consumer as a subscriber
  4. All of these statements are true.

Answer(s): A
