Understanding Questions
- Why did the pings within each team succeed?
- All devices within the team share the same network ID and subnet mask.
- Why did the cross-network pings fail?
- The cross-network pings fail because the networks are not connected. You’d need to connect the switches or use a layer-3 device.
- All devices have a default gateway configured (192.168.10.1 or 192.168.20.1), but those gateways don’t exist yet. Why did the within-team pings still work?
- A default gateway is used for reaching destinations outside of the local subnet; for traffic within the same subnet, hosts resolve the destination IP to a MAC using ARP.
- Based on what you’ve learned, what would we need to add to allow the Creative Team to communicate with the Sales Team?
- You’d need to add a layer 3 device, such as a router with two interfaces configured for 192.168.10.1 and 192.168.20.1
