  • B. Create an IAM role in the development accounts. Add the ec2:DescribeInstances permission to the role. Establish a trust relationship with the shared account for this role. Update the Lambda function IAM role in the shared account by adding the iam:AssumeRole permissions.
  • C. Create an IAM role in the shared account. Add the ec2:DescribeInstances permission to the role. Establish a trust relationship between the development accounts for this role. Update the Lambda function IAM role in the shared account by adding the iam:AssumeRole permissions.
