You are working as an AWS administrator in a fintech startup. The AWS account uses the AWS Business Support plan, and you get access to all the Trusted Advisor checks and recommendations. Trusted Advisor reported a security issue regarding an EC2 instance Security Group one month ago. However, the team has not noticed the issue until a recent security attack. Now you need to set up weekly email notifications for the Trusted Advisor check results. Which of the following methods is the easiest?

Answer options:

A.In the Trusted Advisor console, choose Preferences and enable Weekly Email Notification.
B.Create a weekly CloudWatch Event rule for the Trusted Advisor reporting service.
C.Create a Lambda function that collects the check results through the Trusted Advisor API and forwards the results to an SNS topic. Execute the Lambda function every week.
D.In the AWS account settings, register the email address in the alternate security contact. AWS Business Support plan automatically forwards Trusted Advisor reports to the security contact weekly.

Correct Answer: A
Option A is CORRECT because this method is the most straightforward by enabling the weekly report in the Trusted Advisor Preferences:
Option B is incorrect because there is no Trusted Advisor reporting service in the CloudWatch Event rule.
Option C is incorrect because the Lambda function can be avoided here since Trusted Advisor supports weekly notifications. As the question asks for the easiest one, option A should be chosen.
Option D is incorrect because the AWS Business Support plan does not automatically forward the Trusted Advisor reports. Uses need to enable it in Trusted Advisor.
