If an incident or outage occurs, network administrators must be able to respond effectively and resolve network problems in a timely fashion. In this course, you'll learn about best practices for identifying a problem, establishing a theory of probable cause, testing theories, formulating a plan of action to resolve a problem, implementing a solution, or escalating the issue. You'll explore how to verify full system functionality and document findings, actions, outcomes, and lessons learned. You'll examine how to troubleshoot common cable connectivity issues and explore network specifications and limitations, cable considerations, and common issues such as attenuation, interference, bad ports, and duplexing issues. Lastly, you'll learn about common cable connectivity tools including cable crimpers, punchdown tools, tone generators, loopback adapters, and cable testers. This course is one of a collection of courses that prepares learners for the N10-008: CompTIA Network+ certification exam.
