Multiple Choice

A SysOps Administrator has written an AWS Lambda function to launch new Amazon EC2 instances and deployed it in the us-east-1 region. The Administrator tested it by launching a new t2.nano instance in the us-east-1 region and it performed as expected. However, when the region name was updated in the Lambda function to launch an EC2 instance in the us-west-1 region, it failed. What is causing this error?

A) The AMI ID must be updated for the us-west-1 region in the Lambda function as well
B) The Lambda function can only launch EC2 instances in the same region where it is deployed
C) The Lambda function does not have the necessary IAM permission to launch more than one EC2 instance
D) The instance type defined in the Lambda function is not available in the us-west-1 region
