Can you answer the questions?
What are broadcast and collision domains. Can you prove the answers?
A broadcast domain is a logical division of a computer network, in which all nodes can reach each other by broadcast at the data link layer. A broadcast domain can be within the same LAN segment or it can be bridged to other LAN segments.
In terms of current popular technologies, any computer connected to the same Ethernet repeater or switch is a member of the same broadcast domain. Further, any computer connected to the same set of inter-connected switches/repeaters is a member of the same broadcast domain. Routers and other higher-layer devices form boundaries between broadcast domains.
This is as compared to a collision domain, which would be all nodes on the same set of inter-connected repeaters, divided by switches and learning bridges. Collision domains are generally smaller than, and contained within, broadcast domains.
While some layer two network devices are able to divide the collision domains, broadcast domains are only divided by layer 3 network devices such as routers or layer 3 switches. Separating VLANs divides broadcast domains as well.

This is one of multiple CCNA quiz based videos.
These quizzes are practical and use packet tracer to help you test and verify your knowledge of CCNA topics.
So download the attached packet tracer file and see if you can practically answer the questions in these quizzes.
So don’t just answer the questions, prove it by using the packet tracer simulation mode.
So assume that for these questions that all devices have just rebooted.
You can simulate this by clicking the power cycle devices button in packet tracer.
In other words, you can click this button here to power cycle the devices.
Again, don’t just answer these questions, prove it.
The first question is, when PC 1 pings PC 4 in network 1, what type of packet is sent to the hub initially?
Can you prove it?
Who received the packet?
Who received the return traffic from PC 4 to PC 1 and when ping traffic is sent from PC 1 to PC 4, who receives that traffic?
For question 5 to 8, assume that the switches’ MAC address table is empty.
So assume that this layer 2 switch in network 2 has just rebooted and that it’s MAC address table is empty. When PC 5 pings PC 8, in other words this PC here pings the IP address of PC 8.
What type of packet is sent initially to the switch and can you prove it?
And then again, who received the initial packet and who received the return traffic from PC 8 to PC 5?
And then when ICMP traffic or ping traffic is sent from PC 5 to PC 8, who received the traffic?
Question 9,10 and 11 asked about broadcast and collision domains.
How many broadcast domains are there in network 1 and can you prove it?
How many broadcast domains are there in network 2 and can you prove it?
How many collision domains are there in network 1 and network 2 and again can you prove that?
You don’t have to answer these questions from question 1 to question 11. You may want to answer questions 9,10 and 11 first and then answer the other questions. But by the time you finished, you should be able to answer these 11 questions and be able to prove the answers practically.
So download the attached packet tracer file and see if you can answer the questions yourself. But I’m now going to go through the answers to these questions.
I’m going to answer the questions practically now, so either pause the video or continue watching.
