{
  "Targets": [
    {
      "Id": "MyLambdaTarget",
      "Arn": [1]
    }
  ]
}

Fill both blanks to create an event pattern that matches S3 object creation events in a specific bucket.

AWS

{
  "EventPattern": {
    "source": [[1]],
    "detail": {
      "bucket": {
        "name": [[2]]
      }
    }
  }
}

Drag options to blanks, or click blank then click option'

A"aws.s3"

B"aws.s3.object"

C"my-bucket-name"

D"example-bucket"

💡 Hint

Common Mistakes

Using incorrect source strings like 'aws.s3.object'.

Using wrong or placeholder bucket names.

The source for S3 events is 'aws.s3' and the bucket name must be the exact bucket string.

Fill all three blanks to define a CloudWatch Event rule that triggers on EC2 instance start and sends to an SNS topic.

AWS

{
  "Name": "EC2StartRule",
  "EventPattern": {
    "source": [[1]],
    "detail-type": [[2]]
  },
  "Targets": [
    {
      "Id": "SendToSNS",
      "Arn": [3]
    }
  ]
}

Drag options to blanks, or click blank then click option'

A"aws.ec2"

B"EC2 Instance State-change Notification"

C"arn:aws:sns:us-east-1:123456789012:MyTopic"

D"aws.sns"

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong source or detail-type strings.

Incorrect ARN format or service for target.

The source is 'aws.ec2', detail-type matches EC2 state changes, and the target ARN is the SNS topic ARN.
