Use the export keyword to export the output of the stack. Import the output value in the target stack using the ```ImportValue``` function.

Outputs of a stack can be addressed using the following syntax:
```
StackID.Outputs.OutputName
```

Use the ```Sub``` function to substitute the output value of the stack.

Outputs of a stack can be addressed using the following syntax:
```
!GetAtt StackResource.Outputs.OutputName
```

Increase the `WaitCondition` timeout to one hour and complete troubleshooting within the hour.

Create the instance with ```DeletionPolicy: Retain```.

Configure the stack to not roll back if the stack run fails.

**(Select all that apply.)** You use `WaitCondition` and `cfn-signal` while creating EC2 instances with user data. However, as soon as the `WaitCondition` times out, CloudFormation rollback deletes the EC2 instance and you're unable to troubleshoot.

Recreate the EC2 instance with the same configuration and rerun the stack.

Skip the EC2 instance while updating the stack.

**(Select all that apply.)** You have a CloudFormation stack with multiple resources—security groups, EC2 instances, and one RDS database. A new recruit on your team accidentally deleted an EC2 instance created by the stack. When you were trying to update the stack, it failed and is now in a `UPDATE_ROLLBACK_FAILED` state.
