Q143. Your company has a logging microservice which is used to generate logs when users have entered certain commands in another application. This logging service is implemented via an SQS standard queue that an EC2 instance is listening to. However you have found that on some occasions the order of the logs are not maintained. As a result it becomes harder to use thisservice to trace users' activities. How should you fix this issue in a simple way?
A.Convert the existing standard queue into a FIFO queue. Add a deduplication ID for the messages that are sent to the queue. B.Delete the existing standard queue and recreate it as a FIFO queue. As a result the order for the messages to be received is ensured. C.Migrate the whole microservice application to SWF so that the operation sequence is guaranteed. D.The wrong order of timestamps is a limitation of SQS which does not have a fix.正确答案B
