Course: Cybersecurity Systems Technology, Advanced (10109-IV) > Section: Troubleshooting Networks

Troubleshooting should include an explanation of how to solve the problem, and the following:

- Shorts
- Opens
- Incorrect termination (mismatched standards)
  - Straight-through
  - Crossover

- Cross-talk
  - Near end
  - Far end

- Electromagnetic Interference (EMI)/Radio Frequency Interference (RFI)
- Distance limitations
- Attenuation/Decibel (Db) loss
- Bad connector
- Bad wiring
- Split pairs
- Tx/Rx reverse
- Cable placement
- Bad Small Form-factor Pluggable (SFP)/Gigabit Interface Converter (GBIC)
  - Cable or transceiver

Process/Skill Questions:

- What methods can be used to mitigate EMI/RFI?
- What is cross-talk? What are some methods to eliminate it?
