Which is true about the DNS in relation to Active Directory?

The importance of Domain Name System (DNS) in relation to Active Directory is crucial for the operational success of the environment. DNS provides a naming convention that enables users and services to resolve domain names to IP addresses, which is essential for communication within the network.

Active Directory heavily relies on DNS for various functions, including locating domain controllers and other resources across the network. When a user attempts to access resources, DNS helps resolve the destination names to the correct network addresses. Without a functioning DNS, Active Directory wouldn't be able to authenticate users, replicate directory information, or locate resources such as shared files and printers efficiently.

The configuration and management of DNS must be executed correctly for Active Directory to function optimally, making it integral rather than optional. Therefore, understanding and implementing DNS properly is vital for maintaining a healthy Active Directory infrastructure.
