A Healthcare Company Runs a Production Workload on AWS That

A healthcare company runs a production workload on AWS that stores highly sensitive personal information. The security team mandates that, for auditing purposes, any AWS API action using AWS account root user credentials must automatically create a high-priority ticket in the company's ticketing system. The ticketing system has a monthly 3-hour maintenance window when no tickets can be created. To meet security requirements, the company enabled AWS CloudTrail logs and wrote a scheduled AWS Lambda function that uses Amazon Athena to query API actions performed by the root user. The Lambda function submits any actions found to the ticketing system API. During a recent security audit, the security team discovered that several tickets were not created because the ticketing system was unavailable due to planned maintenance. Which combination of steps should a solutions architect take to ensure that the incidents are reported to the ticketing system even during planned maintenance? (Choose two.)

A) Create an Amazon SNS topic to which Amazon CloudWatch alarms will be published. Configure a CloudWatch alarm to invoke the Lambda function.
B) Create an Amazon SQS queue to which Amazon CloudWatch alarms will be published. Configure a CloudWatch alarm to publish to the SQS queue.
C) Modify the Lambda function to be triggered by messages published to an Amazon SNS topic. Update the existing application code to retry every 5 minutes if the ticketing system's API endpoint is unavailable.
D) Modify the Lambda function to be triggered when there are messages in the Amazon SQS queue and to return successfully when the ticketing system API has processed the request.
E) Create an Amazon EventBridge rule that triggers on all API events where the invoking user identity is root. Configure the EventBridge rule to write the event to an Amazon SQS queue.
