Correct Answer: C, E, FTo meet the requirements of receiving an alert when a root user logs in and displaying log activity on a dashboard, the company should follow these steps: First, create an AWS CloudTrail organization trail to capture all activities, including root user logins, across all accounts and send these events to Amazon CloudWatch Logs. Second, create an Amazon CloudWatch Logs metric filter to match root user login events, and configure a CloudWatch alarm and an Amazon Simple Notification Service (Amazon SNS) topic to send alerts to the company's monitoring system. Third, use CloudWatch Logs Insights to create queries to extract and visualize log data related to root user activity on a CloudWatch dashboard, providing a centralized view of root user actions.
