Question 7

The company you are working with wants to integrate an environment control system into the facility security and monitoring system. The environment control system sends temperature andhumidity readings every half second. What is the best message exchange pattern to use for this integration and why?

A. The request-response message exchange pattern is the best pattern for this scenario because the security and monitoring system needs to provide a response message to the environment control system. B. The reliable one-way message exchange pattern is the best pattern for this scenario because it provides a status return code so that a lost message can be re-sent. C. The buffer-and-send message exchange pattern is the best pattern for this scenario because the messages from the environment control systems are grouped together and sent less frequently in larger messages thus reducing network traffic. D. The one-way message exchange pattern is the best pattern for this scenario because it requires the least network resources and if a message is lost, another message with more up-to-date information will be sent in less than a second. E. The request optional-response message exchange pattern is the best pattern for this scenario because the security and monitoring system may want to provide a response message to the environment control system.
