Exam AWS Certified Developer Associate topic 1 question 153 discussion

I think A, don't need to wait schedule , message ,batch, just focus on real-time event-trigger and process

Odd question. Let's have a look at "fan-out" definition: "In message-oriented middleware solutions, fan-out is a messaging pattern used to model an information exchange that implies the delivery (or spreading) of a message to one or multiple destinations possibly in parallel, and not halting the process that executes the messaging to wait for any response to that message". https://en.wikipedia.org/wiki/Fan-out_(software) Can't choose between A and C.

Event driven architecture is the correct answer

I found some useful explanations of event driven arch. https://ably.com/blog/introduction-event-driven-architecture

I think it should be D! A-Event Driven archi' are triggered to run when there is an event like a notification, data push etc. B-Client-Server does not make sense at all C-Fan-out is also similar to A, like SQS-SNS fanout archi' when SNS receives a notificaiton and SQS will process the data . The question asks about analysis to be done in the night batch and to be processed by the next day. Hence Scheduling it using CRON jobs, Eventbridge, Lambda Functions can be used

This question was on the exam today (Feb 2023)

A it is

Its A the others are not options

AAAAAAA

I choose A. Event driven = real time

i think A is the only real driven

A event-driven
