Phase 1

Phase 1 Troubleshooting Fundamentals focuses on the foundational skills required for effective network troubleshooting. These labs introduce beginner-level concepts and emphasize the basic principles that every network engineer must understand before working with more complex environments. They are most suited for individuals early in their networking study journey who are building their understanding of core networking behaviors and troubleshooting techniques.

Learners are encouraged to attempt the lab on their own and use the guide when they need assistance or want to understand the reasoning behind the solution.
