Selected Answer: AC
Option A is correct because an Amazon EventBridge rule can be created to detect when an object is created in an S3 bucket. The rule should be configured with a pattern to match the S3 object created event. Option C is correct because the existing Lambda function can be updated with an EventBridge trigger. The trigger type should be set to EventBridge, and the Amazon EventBridge rule created in step A should be selected.

EventBridge allows you to trigger actions (like Lambda functions) based on specific events (like S3 object uploads).

For the options given as answers, A and C is the viable option. But its a stupid solution... you can use s3 events to trigger it directly.

ChatGPT: AC A. Create an Amazon EventBridge rule. Configure the rule with a pattern to match the S3 object created event. This sets up an EventBridge rule to respond to S3 object creation events. C. Add a trigger to the existing Lambda function. Set the trigger type to EventBridge. Select the Amazon EventBridge rule. This associates the Lambda function with the EventBridge rule, ensuring that the Lambda function is triggered when the specified event occurs.

Lambda functions are not currently supported as triggers directly from EventBridge rules.Lambda can be used as the target of an EventBridge rule, but is not added to a Lambda function as a trigger.

Why not just use the S3 event as the trigger directly.
