To configure selective authentication in the target domain, which type of trust is being created?

Selective authentication is a method used in Active Directory environments where specific accounts from a trusted domain are allowed access to resources in a target domain. When selectively authenticating, only the necessary users or groups are granted access, rather than all users from the trusted domain.

In the context of trust relationships, a one-way incoming trust allows a domain to trust the authentication requests from another domain while not trusting the other domain in return. This means that only the trusted domain's users can be authenticated to access resources in the target domain. This aligns perfectly with the concept of selective authentication, as it provides control over which users from the trusted domain are allowed access, rather than providing blanket access to all users in that domain.

The other types of trusts, such as external trust and forest trust, serve different purposes. An external trust is used to provide a secure connection between a non-Active Directory domain and an Active Directory domain. A forest trust is established to allow two Active Directory forests to share authentication across domains but does not imply selective access to resources. A two-way trust, on the other hand, allows both domains to trust each other fully, which does not align with the selective authentication approach.

With this understanding, it is clear that the creation of a one-way incoming
