Summary

A layered model helps you develop a structured plan to repair any network issue, whether it is a bottom-up, top-down, or divide-and-conquer approach. Your troubleshooting success also hinges on your knowledge of the protocols, connections, and configurations of LANs and WANs alike. Day 26 focuses on the common physical connections and ports you encounter on a network. You can further review the topics from today on pages 5–36 for the OSI model and pages 255–292 for WAN features in CCNA Flash Cards and Exam Practice Pack (CCENT Exam 640-822 and CCNA Exams 640-816 and 640-802), Third Edition.
