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).
Translation:
Okay so let’s see if we can answer these questions practically by using packet tracer.
The first thing I’ll do is power cycle the devices to ensure that devices have just booted up. We’ll need to wait until all the links have done green before we can send a ping from PC 1.
Here’s PC 1, I’ll open up a command prompt. IP address of this PC is 10.1.1.1; default gateway is 10.1.1.2.5.4 which should be ISR Router 1.
show ip interface brief
shows us the IP address of the router that’s the IP address of Router 1.
The interfaces in packet tracer have now gone green. So I’ll go to simulation mode, edit the filters and make sure that only ARP and ICMP are enabled.
Back on PC 1, we need to ping PC 2, in other words 10.1.3.2
We can see in packet tracer that an ICMP message is being sent but PC 1 needs to know the MAC address of its default gateway.
So the PC is sending out an ARP request. We can see in the output that the source MAC address is this, destination MAC address is a broadcast, source IP address is PC 1; destination IP address is the router.

Setting up your Windows workstation as a development environment: Install bash, git, Python, atom, Postman, Docker and more!
So you are a follower of Gates, Balmer and Nadella, excellent! Let's supercharge that Windows workstation with everything you need to be a programability ninja!
Objectives:
- Install a basic development toolset on your local workstation
-Verify the tools are all working as expected
Prerequisites:
In this lab you'll find walkthroughs on how to install a set of common development tools on a Windows 10 workstation. If you haven't reviewed the lab "What is a Development Environment, and why do you need one?" yet, you may want to go back and take a look. In it, you will learn the reasons behind the types of tools and choices made for this lab.

What are the OSI and TCP/IP models? Why do we care? And why do some people say the OSI model is a lie? Time to find out!
DavidBombal.com: CCNA ($10): http://bit.ly/yt999ccna
???support the mission, join thisisIT: https://bit.ly/thisisitccna
My advice: Don't get caught up in the debates. Learn what is important for the CCNA exam which is the TCP/IP model. Know your protocols, but don't get too concerned about where everything fits. Nothing in life is simple.
This is video #8 of my FREE CCNA Course 200-301 - a complete CCNA course for the new Cisco CCNA exam. I am going to be covering all the topics in the exam blueprint in this course.
I want to make this content practical and it will include a lots of labs and demonstrations to help you better understand topics on the exam.
The course will contain:
- Videos
- Labs using Cisco Packet Tracer
- Quiz Questions
- And more!
