Describe How A Network Works
- Describe the purpose and functions of various network devices.
- Select the components required to meet a network specification.
- Use the OSI reference model and its associated protocols to explain how data flows in a network.
- Describe the purpose and basic operation of the protocols in the OSI reference model.
- Determine the path between two hosts across a network.
- Describe the components required for network and Internet communications.
- Identify and correct common network problems at layers 1, 2, 3 and 7 using a layered model approach.
- Differentiate between LAN/WAN operation and features.
- Differentiate between IP addresses, MAC addresses, and at which phase and layer of the OSI Reference Model each type of address is used.
Diagnostics & Troubleshooting Commands
- ICMP (Internet Control Message Protocol)
- Traceroute and how TTL is used with Traceroute.
- e.g. Does the router evaluate TTL before or after decrementing TTL, to determine if the packet should be forwarded?
- ipconfig /all
- tracert (on Windows) or traceroute (on Linux)
- show ip interface brief
- show ip route
- show ip protocol
- show controllers s0/0 (To determine if a serial interface is DCE or DTE)
- Techniques used to make the size of the routing table manageable.
- Next-Hop Method
- Network-Specific Method
- Default Method
Delivery of a Packet
- Direct Delivery
- Indirect Delivery
Logical and Physical addressing during the forwarding process:
