This is one of multiple CCNA Exam Simulation quiz questions.
Can you answer the questions yourself? In these quiz questions
I'm using Cisco Packet Tracer to help you practically test and verify your knowledge of Cisco CCNA
topics. In these quiz questions
we are testing your knowledge of the life of a packet.
Do you understand destination and source MAC addresses?
Do you understand where those are used?
Do you understand how traffic flows through a network and the various encapsulation used in a network?
In this scenario I have two PCs.
PC 1 on the left and PC 2 on the right they are connected to 3650 switches.
These switches are configured as layer 2 switches.
There are also two Cisco ISR routers connected via a serial link.
The scenario is PC1 pings PC 2 you need to answer the following questions based on the Echo
request message sent from PC 1 to PC2.
So look at the echo request message, not other traffic types and answer these questions.
What is the destination MAC address of the frame at point A in the network?
In other words, what is the destination MAC address of the Echo request message?
At this point what is the actual destination MAC address?
So, in other words, you need to determine what are the actual MAC addresses by looking at the frame and
determining to which device that MAC address belongs now to help you with this task in Packet Tracer
use of the simulation mode, simulation mode in Packet Tracer allows you to simulate the flow of traffic
through a network and view what happens. Once you open up simulation mode on PC 1 generate traffic
so send a ping to the IP address of PC2 which is 10 132
and have a look at how the traffic flows as we can see here, an ARP packet has been created and the
PC is arping for the MAC address of the router if you don't want to see other traffic types you
can edit your filters to only look at ARP and ICMP traffic within Packet Tracer.
So what I'll do is reset that simulation and send the packet again
so we can see the ARP request to the router and the reply and then we can see the ICMP message.
And if you click on the message you'll be able to view the inbound PDU and outbound PDU and then
answer the questions, so by using simulation mode or by simply looking at the configurations of the devices
in the topology, you should be able to answer these questions. So there are various questions asking about
MAC addresses and encapsulations used at different stages in the life of the packet
for both
Echo request and echo reply. Do you know how packets are encapsulated?
Do you know when MAC addresses are used and when they're not used?
Download the attached packet tracer file and see if you can answer these questions yourself.
Otherwise watch the next video
where I show you the answers to these questions.
