When authenticating with a domain controller using only the domain controller agent, what can occur?

When authenticating with a domain controller using only the domain controller agent, it is important to consider the specific functionalities and limitations of this agent. The domain controller agent works to facilitate user authentication by communicating directly with the domain controller, but if it operates independently without collaboration from other components such as the collector agent, certain challenges arise.

One significant issue that can occur is that the user may not be authenticated successfully. This can happen because the domain controller agent requires proper configuration and may need to align with other components in the authentication process to ensure that users are validated correctly against the domain controller's database. If the agent is configured improperly, or if there are communication issues between the domain controller and the agent, the authentication attempts may fail.

This context clarifies why the selection that indicates users cannot be authenticated is accurate. Other options may suggest alternative dynamics of the authentication process, but understanding the role of the domain controller agent in isolation helps highlight the necessity of correct setup and the potential for failed authentications.
