Question 4: 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 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.
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 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.
D. 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.
E. 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.
