Question 237

A company has an event-driven JavaScript application. The application uses decoupled AWS managed services that publish, consume, and route events. During application testing, events are not delivered to the target that is specified by an Amazon EventBridge rule.

A DevOps team must provide application testers with additional functionality to view, troubleshoot, and prevent the loss of events without redeployment of the application.

Which combination of steps should the DevOps team take to meet these requirements? (Choose three.)

Launch AWS Device Farm with a standard test environment and project to run a specific build of the application.

Create an Amazon S3 bucket. Enable AWS CloudTrail. Create a CloudTrail trail that specifies the S3 bucket as the storage location.

Configure the EventBridge rule to use an Amazon Simple Queue Service (Amazon SQS) standard queue as a dead-letter queue.

Configure the EventBridge rule to use an Amazon Simple Queue Service (Amazon SQS) FIFO queue as a dead-letter queue.

Create a log group in Amazon CloudWatch Logs Specify the log group as an additional target of the EventBridge rule.

Update the application code base to use the AWS X-Ray SDK tracing feature to instrument the code with support for the X-Amzn-Trace-Id header.

Correct Answer: B, C, E

To meet the requirements without redeploying the application, the DevOps team should create an Amazon S3 bucket and enable AWS CloudTrail to log AWS API calls for auditing purposes. Additionally, they should configure the EventBridge rule to use an Amazon SQS standard queue as a dead-letter queue, thereby capturing events that could not be delivered. Finally, specifying a log group in Amazon CloudWatch Logs as an additional target of the EventBridge rule will provide detailed logs of the events, allowing for thorough troubleshooting and analysis.

CEF, X-ray enables you to debug distributed applications to troubleshoot the root cause of performance issues and errors

without redeployment of the application. B,C,E

---> CEF I thought E its not possible, but --> https://repost.aws/knowledge-center/cloudwatch-log-group-eventbridge

tgv

good catch with "without redeployment of the application." B, C, E

trungtdOptions: CEF

C allows you to capture events that could not be delivered to the specified target E capture detailed logs of the events that are processed F end-to-end tracing capabilities B is wrong because while CloudTrail provides logging for AWS API calls, it is not specifically designed for capturing and troubleshooting event flows in EventBridge
