This course reviews troubleshooting methods used in Layer 1 and Layer 2 of the OSI Model. The course covers how to detect, trace, identify, and fix network connectivity issues at the Physical and Data Link layers of the OSI stack. The basics of the Physical and Data Link layers will be covered along with a review of the devices, signaling, and cabling which operate at these layers. Students will be presented with methods for tracing connectivity issues back to the source and identifying mitigation solutions.
- Understand basic overview of components of the first two layers of the OSI model
- Recognize common issues associated with Layer 1 & 2 of the OSI model
- Apply troubleshooting methods associated with the Physical and Data Link Layer
