Can you answer the questions?

The Address Resolution Protocol (ARP) is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given network layer address, typically an IPv4 address. This mapping is a critical function in the Internet protocol suite. ARP was defined in 1982 by RFC 826,[1] which is Internet Standard STD 37.

ARP has been implemented with many combinations of network and data link layer technologies, such as IPv4, Chaosnet, DECnet and Xerox PARC Universal Packet (PUP) using IEEE 802 standards, FDDI, X.25, Frame Relay and Asynchronous Transfer Mode (ATM). IPv4 over IEEE 802.3 and IEEE 802.11 is the most common usage.

In Internet Protocol Version 6 (IPv6) networks, the functionality of ARP is provided by the Neighbor Discovery Protocol (NDP).

This is one multiple packet tracer quiz questions.
These quizzes are practical and use packet tracer to help you practically verify your knowledge of CCNA topics.

In this packet tracer topology, we have 2 PCs: PC 1 and PC 2 which are connected to layer 2 switches. PC 1 is connected to a 3650, the layer 2 switch and so is PC 2.
Switches in turn are connected to ISO routers which are connected via a serial interface.

In this quiz, you need to assume that the devices have just booted. You can simulate to the packet tracer by clicking the power devices button. So in other words click here to power cycle the devices.

So in this scenario, what’s going to happen when PC 1 pings PC 2 after the devices have just booted up. As you can see in this topology the interfaces are changing from red to orange to green. Wait for all links to turn green and then answer these questions.

When PC 1 pings PC 2, at which points on the network are ARP message is sent?
So will ARP requests and replies be sent at point A, point B, point C, point D or point E or all of them where are ARP message is used?
So what’s your answer to that question?

Question 2, what is the MAC address requested by ARP at point A?
So in other words, when PC 1 pings PC 2, what is the MAC address requested by PC 1 at point A?
What is the MAC address requested by ARP at point C?
What is the MAC address requested by ARP at point E?
And for extra credits, you can also answer the question, what is the MAC address requested by ARP at point B and point D?

Question 5: What is the destination at layer 2 address of the ARP request at point A?
So what is the destination MAC address at this point?
What is the destination layer 2 address of the ARP reply at point A?

Notice that it is different to question 5. You need to provide the answer for the ARP request and reply messages.

Question 7: What do layer 2 switches do with ARP request messages?
Assume that you have a single VLAN.
Now to help you answer these questions; use packet tracer simulation mode.
So start simulation mode and enable packet tracer for ARP and ICMP and then on PC 1, send a ping to PC 2 and use packet tracer simulation mode to answer the questions.

So look at the messages that are sent.
Look at the OSI model information.
Look at the inbound PDU and outbound PDU information and then answer these questions. Don’t just answer the questions; verify that you’re answering the questions correctly by using simulation mode and looking at the actual packets in the network.

So can you answer these questions yourself?
Download the attached packet tracer file and see if you can answer all these question yourself or otherwise watch the next video where I answer the questions.
