Exam question from Amazon's AWS Certified Developer - Associate DVA-C02
Question #: 292
Topic #: 1
[All AWS Certified Developer - Associate DVA-C02 Questions]

A developer is investigating an issue in part of a company's application. In the application, messages are sent to an Amazon Simple Queue Service (Amazon SQS) queue. The AWS Lambda function polls messages from the SQS queue and sends email messages by using Amazon Simple Email Service (Amazon SES). Users have been receiving duplicate email messages during periods of high traffic.

Which reasons could explain the duplicate email messages? (Choose two.)

  • A. Standard SQS queues support at-least-once message delivery.
  • B. Standard SQS queues support exactly-once processing, so the duplicate email messages are because of user error.
  • C. Amazon SES has the DomainKeys Identified Mail (DKIM) authentication incorrectly configured.
  • D. The SQS queue's visibility timeout is lower than or the same as the Lambda function's timeout.
  • E. The Amazon SES bounce rate metric is too high.
