A server technician has just installed a server with several roles. After running the netstat command, which server role is MOST likely installed given the listening ports: 88, 389, 464, 3268, and 3269?

The listening ports displayed—88, 389, 464, 3268, and 3269—are indicative of a Directory server, particularly one that supports Active Directory services. Each of these ports serves specific functions related to directory services.

Port 88 is used for Kerberos authentication, which is essential in environments that require secure authentication. Port 389 is used for the Lightweight Directory Access Protocol (LDAP), which is the protocol utilized to access and maintain distributed directory information services. Port 464 is also associated with Kerberos and is used for password changes. Ports 3268 and 3269 are used for the Global Catalog service in Active Directory, allowing for efficient searching of directory information across multiple domains.

Given this context, the presence of these specific ports strongly suggests that the server is functioning as a Directory server, which is critical for managing users, computers, and services in network environments. The other options—Database server, Mail server, and Web server—do not primarily utilize these ports, making them less likely candidates based on the provided port information.
