What benefit does having two servers in an Active Directory environment provide?

Having two servers in an Active Directory environment primarily offers enhanced service availability and reliability, effectively addressing potential network performance issues should one server fail. When one server experiences a problem, the other can seamlessly handle requests, minimizing downtime and ensuring that users can still authenticate and access resources without interruption.

This setup is crucial for business continuity, as it helps maintain access to directory services, user authentication, and other critical operations. Therefore, having a secondary server acts as a failover solution, which is essential for maintaining seamless network performance and user experience during server outages or maintenance periods.

While the other options highlight important aspects of server functionality—such as redundancy for file storage, security measures, or cost considerations—they do not specifically articulate enhancement to network performance and server reliability in the context of Active Directory services.
