If we have 2 AD Domains, Domain A and Domain B with a trust between them, can SSO authenticate users to their respectivetive domains? Meaning a user from Domain A will be authenticated from Domain A and a user from Domain B will be authenticated from Domain B?

Yes. Ignoring fault tolerance and redundancy for a moment... One option is to install an Okta AD agent in each domain. Another is to install a single AD agent, using a service account that has the appropriate rights in both domains, on a server with the necessary ports open to the domain controllers in both domains. After installing the agent, you just have to add both domains to the agent configuration. This is actually the configuration we've been using for the last 5 years, to authenticate users in 3 domains across 2 forests. And for fault tolerance, this same configuration is installed on 4 servers - two on-premises and two in AWS.
