# Create a practice run configuration
<a name="getting-started-cli-update-zonal_autoshift.create-practice-run"></a>

Before you can enable zonal autoshift for a resource, you must create a practice run configuration for the resource, to choose options for the required practice runs. You create a practice run configuration for a resource with the CLI by using the `create-practice-run-configuration` command.

Note the following when you create a practice run configuration for a resource:
+ The only supported alarm type at this time is `CLOUDWATCH`.
+ You must use alarms that are in the same AWS Region that your resource is deployed in.
+ Specifying an outcome alarm is required. Specifying a blocking alarm is optional.
+ Specifying blocked or allowed dates or windows is optional.

You create a practice run configuration with the CLI by using the `create-practice-run-configuration` command.

For example, to create a practice run configuration for a resource, use a command like the following:

```
aws arc-zonal-shift create-practice-run-configuration \
      --resource-identifier="arn:aws:elasticloadbalancing:{{Region}}:{{111122223333}}:{{ExampleALB123456890}}" \
      --outcome-alarms type=CLOUDWATCH,alarmIdentifier=arn:aws:cloudwatch:{{Region}}:{{111122223333}}:alarm:{{Region}}-{{MyAppHealthAlarm}} \
      --blocking-alarms type=CLOUDWATCH,alarmIdentifier=arn:aws:cloudwatch:{{Region}}:{{111122223333}}:alarm:{{Region}}-{{BlockWhenALARM}} \
      --blocked-dates 2023-12-01 --blocked-windows Mon:10:00-Mon:10:30
```

```
