Foundational Network Diagnostics

О курсе

Learn how to diagnose common network connectivity problems by applying practical, hands-on techniques used in real support and operations environments. In this course, you’ll build the ability to analyze client-side DNS and DHCP failures, use basic network utilities to test and trace routing paths, and verify the operational state and connectivity of network devices using foundational diagnostic commands. You’ll also practice gathering initial incident data with standard network troubleshooting tools so you can quickly narrow down likely causes and next steps. You’ll progress through structured troubleshooting workflows, OS-based diagnostic practice, and core network fundamentals. Content spans systematic troubleshooting methods and command-line verification (including tools such as ping, traceroute, and DNS/port-testing utilities like nslookup/dig and netstat/curl/telnet/nc), then reinforces the underlying concepts needed to troubleshoot confidently. Hands-on work may use a lab workstation running Windows, macOS, or Linux with admin access, plus a virtualized networking lab environment with a router/switch OS that supports Cisco-style CLI and IPv4/IPv6 configuration; optional cabling practice can be supported with basic Ethernet patch cables and a tester/crimper. This multi-author experience brings complementary perspectives from Packt and Google, helping you learn to troubleshoot across different environments and approaches. Ideal for learners preparing for entry-level networking roles, IT support responsibilities, or anyone who wants a practical foundation in network diagnostics and troubleshooting.
