What is a major benefit of establishing trusts between domains?

Establishing trusts between domains significantly simplifies user access to resources. When trusts are in place, users from one domain can be granted access to resources (such as files and applications) in another domain without needing to create separate user accounts for each domain. This streamlined access is especially beneficial in organizations that operate across multiple domains, allowing for efficient resource sharing and collaboration among users. Instead of managing multiple credentials and accounts, users can authenticate once and gain access to relevant resources across trusted domains, thereby improving overall productivity.

The other options do relate to domain management but do not capture the primary advantage as effectively. For instance, while trusts can contribute to enhanced administrative controls through centralized management, the main highlight is the ease of access. Similarly, while trusts might indirectly support network security and data management solutions, these aspects are not the most pertinent benefits of establishing trusts specifically.
