# StrictMode

The `StrictMode` configuration parameter determines how DAH responds when one or more child servers do not respond.

You can choose from one of the following options:

- DAH returns a successful response when at least one child server returns a success response. This is the default mode.

- DAH returns an error response when at least one child server does not return a success response. Use this option if results from all child servers are critical.

- DAH returns an error response if at least one child server fails to respond, but it is otherwise equivalent to the default mode.
