Your question is Layer 2 and 3 Technologies. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about your knowledge of Layer 2 and Layer 3 technologies.
Explain the purpose of each layer, how a packet moves between devices on the same network and across different networks, and the main protocols involved. Include at least one security concern at each layer and describe how you would troubleshoot a connectivity problem.
