SAP-C02 AWS Certified Solutions Architect – ProfessionalExam Practice Test CourseFree Sample Question 1 out of 3:A company wants to build a highly scalable, event-driven architecture to process EC2 instance state change notifications across multiple AWS accounts. They need a central account to receive and process these notifications. The primary goal is to avoid polling EC2 instances directly or relying on custom Lambda functions to check for changes. Which of the following approaches best meets these requirements using AWS services?A. In each source AWS account, create a Lambda function that polls EC2 instances for state changes and then sends a custom event to an SNS topic in the central account.B. In the central AWS account, configure EventBridge to receive events from source accounts by creating EventBridge rules in the source accounts that target the central account's event bus, and set up an SQS queue in the central account as a target for these events.C. In each source AWS account, create CloudWatch Alarms for EC2 state changes and configure these alarms to send notifications to an SNS topic in the central account.D. In each source AWS account, create EventBridge rules to capture EC2 instance state change events and have these rules directly send the events to an SQS queue in the central account.Correct Answer: BExplanation:Option B correctly leverages Amazon EventBridge for centralized event processing and cross-account event routing. In the source accounts, EventBridge rules would be configured to capture EC2 instance state change events. These rules would be set up to send events to the central account's EventBridge event bus. The central account's event bus would then have a resource policy allowing event puts from the source accounts. Finally, an EventBridge rule in the central account would capture these incoming events and deliv
