Quiz Questions:
Assume that all devices have just rebooted (you can simulate this via the Power Cycle Devices Button in Pacet Tracer)
Don’t just answer the questions. Prove it.
1) When PC1 pings PC4, what type of packet is sent to the hub initially? Can you prove it?
To answer this question we need to ping PC4 from PC1. Lets find out what the IP address for each PC is.
We know 10.1.1.4 is PC4s IP address, so we’ll ping PC4 from PC1 in stimulation mode.
All we need to do now is to click on the packet leaving PC1 in stimulation mode.
On Layer 2 we can see the the outbound packet is an ARP Packet with a src of 10.1.1.1, Destination IP 10.1.1.4
2) Who receives the packet?
The Hub recieves the traffic and forwards it to all PCs on the network, but only PC4 recieves the packet.
3) Who receives the return traffic from PC4 to PC1?
We can see below, every other PC except PC4 will recieve the return traffic
4) When ping traffic is sent from PC1 to PC4, who receives the traffic?
To answer this question we need to click on the packet before it leaves the hub.
Here we can see the outbound information is FastEthernet 1,2,3
PC1 is FasthEth0, so every PC on the network recieved a frame except the source of the packet (PC1)
5) Assume that the Switch1’s MAC address table is empty.
When PC5 pings PC8, what type of packet is sent to the switch initially? Can you prove it?
This question is exactly the same as question 1 so follow the same steps for PC5 and PC8
ARP packet.
6) Who receives the packet?
The Switch recieves the packet. And forwards the packet to every device on the network.
7) Who receives the return traffic from PC8 to PC5?
The switch has now learned the MAC address of PC 5 through the ARP reply. The ARP reply includes MAC and IP address information.
Clicking on the packet sent from PC8 to the Switch will reveal the following information
8) When ping traffic is sent from PC5 to PC8, who receives the traffic?
Everyone on the network as the switch as not yet learned the MAC addresses of the devices on the network.
9) How many broadcast domains are there in Network 1? Can you prove it?
Single broadcast domain. The hub has sent a packet to every device on the network.
10) How many broadcast domains are there in Network 2? Can you prove it?
SIngle broadcast domain.
11) How may collision domains in Network 1 and Network 2? Can you prove it?
Network 2 = 4 collision domains. Network 1 has 1 collision domain.
