A DevOps engineer is deploying a new version of a company’s application in an AWS CodeDeploy deployment group associated with its Amazon EC2 instances. After some time, the deployment fails. The engineer realizes that all the events associated with the specific deployment ID are in a Skipped status, and code was not deployed in the instances associated with the deployment group.
What are valid reasons for this failure? (Choose two.)
A. The networking configuration does not allow the EC2 instances to reach the internet via a NAT gateway or internet gateway, and the CodeDeploy endpoint cannot be reached.
B. The IAM user who triggered the application deployment does not have permission to interact with the CodeDeploy endpoint.
C. The target EC2 instances were not properly registered with the CodeDeploy endpoint.
D. An instance profile with proper permissions was not attached to the target EC2 instances.
E. The appspec.yml file was not included in the application revision.
