*Q.* I encountered a *CREATE_FAILED* error when I launched the Quick Start.

*A.* If AWS CloudFormation fails to create the stack, we recommend that you relaunch the
template with Rollback on failure set to No. (This setting is under Advanced in the
AWS CloudFormation console, Options page.) With this setting, the stack’s state will be
retained and the instance will be left running, so you can troubleshoot the issue. You can
examine the `/var/log/cfn-init.log` file for details.

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.

*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.
