Core Exam Topics & Objectives
The exam covers Samba file sharing, LDAP directory services, Active Directory integration, Kerberos authentication, and heterogeneous network administration. You'll be tested on configuring Linux to coexist seamlessly with Windows infrastructure and managing user authentication across systems. These skills directly apply to real enterprise deployments where Linux and Windows must work together.
Samba & Windows Integration
Samba is central to this exam—you must understand SMB/CIFS protocols, domain membership, and file sharing between Linux and Windows clients. In practice, this means configuring Samba as a domain controller, member server, or standalone file share. Mastering Samba configuration files and troubleshooting common authentication failures is essential.
