Correct answer - "ValidateService" : ValidateService is the last deployment lifecycle event. It
is used to verify the deployment was completed successfully.
Incorrect:
"AfterInstall" - You can use this deployment lifecycle event for tasks such as configuring your
application or changing file permissions
"ApplicationStart" - You typically use this deployment lifecycle event to restart services that
were stopped during ApplicationStop
"AllowTraffic" - During this deployment lifecycle event, internet traffic is allowed to access
instances after a deployment. This event is reserved for the AWS CodeDeploy agent and cannot be
used to run scripts
