This book is for students and professionals preparing for the network engineering interviews and discusses hundreds of scenarios based questions with simplified explanations to crack the interviews for the following Potential Job roles such as Network Engineer, Level 1 Support Engineer, Software Engineers building Networking products, Test Engineers, Network Development Engineers, Support EngineersThis book is also helpful for interviewers building and managing a team of network engineers such as Hiring Managers, IT Recruiters, Software Development Managers for Cloud, Delivery Managers for Telecommunication and Service Provider networksAlthough the tone of this book has been set for individuals starting out in the network engineering field however senior network engineers will also find it helpful to brush up their skills.Network engineering is the super glue that binds the several components of the Infrastructure that builds today's Cloud Computing environments such as AWS, Service Provider Networks, Telecommunication networks and other enterprise IP networks.The network engineering questions, and their answers will demonstrate the knowledge to deploy, maintain, secure and operate a medium-sized network using latest networking technologies. We expect that these network engineers can design, install, configure, and operate LAN, WAN, and dial access services for small to large networks using some of these protocols: IP, IGRP, Serial, Frame Relay, IP RIP, VLANs, RIP, Ethernet, Access Lists.
