This lab manual reinforces MCSE certification objectives, prepares students to work in the real world by applying networking concepts to solve real PC hardware and software problems, and provides teachers with a way to assess student knowledge and reinforce learned concepts. Labs challenge students to solve problems based on realistic case studies, while clear, measurable lab objectives map to certification objectives. There are materials lists and lab set-up instructions, and step-by-step lab scenarios that require students to think critically. Hint and warning icons aid students through potentially confusing situations and cross-reference icons link to the Study Guide. The post-lab observation questions measures students' understanding of their lab results and the key term quiz helps to build vocabulary. The back of the book carries solutions that explain not only what happened, but why.
