Hi Chris, not a stupid question. A Trust is a domain level property, when you establish a trust your whole IPA domain is in a trust relationship with the AD domain. Not all IPA servers are also trust controllers automatically, IIRC, but you also do not need all of them to be for redundancy. You may want to read https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/windows_integration_guide/active-directory-trust for a better understanding of what is involved in managing AD trusts, 5.1.6 explains the difference between trust controllers and trust agents.
