== FAQ *Q.* I encountered a *CREATE_FAILED* error when I launched the Quick Start. *A.* If AWS CloudFormation fails to create the stack, relaunch the template with *Rollback on failure* set to *Disabled*. This setting is under *Advanced* in the AWS CloudFormation console on the *Configure stack options* page. With this setting, the stack's state is retained, and the instance keeps running so that you can troubleshoot the issue. WARNING: When you set *Rollback on failure* to *Disabled*, you continue to incur AWS charges for this stack. Delete the stack when you finish troubleshooting. For more information, see https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/troubleshooting.html[Troubleshooting AWS CloudFormation^]. *Q.* I encountered a size-limitation error when I deployed the AWS CloudFormation templates. *A.* Launch the Quick Start templates from the links in this guide or from another S3 bucket. If you deploy the templates from a local copy on your computer or from a location other than an S3 bucket, you might encounter template-size limitations.
