CCENT: Practice & Study Guide

The “CCENT Practice and Study Guide” by Allan Johnson, published by Cisco Press, is a structured workbook designed to help learners prepare for the ICND1 (100-101) certification exam, which leads to the Cisco Certified Entry Networking Technician (CCENT) credential. It includes vocabulary exercises, configuration labs, troubleshooting scenarios, and conceptual reviews that mirror Cisco Networking Academy coursework. The guide systematically walks readers through network fundamentals, switching and routing essentials, IP addressing, subnetting, and security principles, ensuring both theoretical understanding and hands-on proficiency. Essentially, it’s a bridge between classroom learning and real-world network configuration practice, crafted to reinforce mastery of Cisco’s core networking technologies.
