What functions does a global catalog server perform? Select three.

A global catalog server plays a crucial role in Active Directory environments by enhancing search capabilities and access control. One of its primary functions is facilitating domain and forest-wide searches. This means it allows users and applications to query not only their local domain but also to search across all domains in a forest. This capability is vital for organizations that have multiple domains and need to retrieve information consistently and efficiently.

Moreover, it holds vital information about objects in the directory, such as user accounts and groups, but it does not store complete information like login credentials. Instead, the global catalog stores essential attributes that help identify users across various domains. Additionally, it keeps track of universal group memberships, which is important for permission and access management.

As a result, the correct functions performed by a global catalog server include enabling broad searches, storing universal group membership details, and facilitating user logon across multiple domains, making it an essential component for managing a network of multiple domains effectively.
