Zero-Configuration Networking — CompTIA A+ Core 1 (220-1101) Practice Questions
Zero-configuration networking (Zeroconf) is a set of technologies that automates IP address assignment, hostname resolution, and service discovery on a local network without requiring a DHCP server or manual setup. The 220-1101 exam covers Zeroconf components including APIPA for automatic IPv4 addressing, mDNS for name resolution, and DNS-SD for service discovery, which together allow devices like printers and shared drives to be found and used immediately. This is particularly relevant in small office and home office environments where managed infrastructure may not exist. Understanding Zeroconf helps technicians explain why devices sometimes acquire 169.254.x.x addresses and how automatic service discovery works.
