Arcitura Education S90.08 Exam - Topic 3 Question 129 Discussion

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?
B) 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.
A) 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.
C) 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.
D) None of the these statements describe solutions that directly solve this problem.

Just to clarify, polling can lead to unnecessary traffic, right?

Wait, are we really saying polling is still a thing? That seems outdated!

C sounds interesting, but I'm not sure it really addresses the polling issue.

I think A could work too, but it seems a bit complicated.

B is definitely the way to go! Event-driven is much more efficient.

I’m leaning towards option D because I don’t think any of these really tackle the polling inefficiency directly.

I practiced a similar question where we discussed how event-driven systems can improve efficiency. I feel like option B is the best fit here.

I'm not entirely sure, but I think the Messaging Metadata pattern might not fully address the polling issue since it focuses on avoiding duplicates rather than reducing unnecessary requests.

I remember studying the Event-Driven Messaging pattern, and it seems like it would help with notifying consumers instead of them polling constantly.
