("Network Engineer's 5-Day Cultivation" builds a 5-day review structure based on the author's years of experience in soft-examination education and training and test questions research. Through in-depth analysis of the exam outline and summarizing the exam status over the years, this framework highly summarizes and collects all common sense points touched by the network engineer exam, and decomposes the comprehensive exam into related common sense points one by one in the form of a common sense map. Analyse the answers with typical exam questions and specific questions to ensure that you can draw inferences from each other.)
