Microsoft Azure Administrator Associate AZ-104 Practice Question

To allow users to specify a value during deployment and provide a default if none is supplied, you should define an input in the parameters section of the ARM template. In this section, you can declare a parameter, set its type, and assign a default value. The variables section is used for defining values calculated during deployment and doesn't accept user input. Setting the location directly in the resources section would hard-code the value and not allow for user customization or defaults. The outputs section is used for returning values after deployment and is not related to accepting user input.
