Cisco CCNA Lab 1

Exam Objectives


The following exam objective is covered in this lab:

  • 1.1 Explain the role and function of network components

  • 1.2 Describe characteristics of network topology architectures

  • 1.5 Compare TCP to UDP

Note: Our main focus is to cover the practical, hands-on aspects of the exam objectives. We recommend referring to course material or a search engine to research theoretical topics in more detail.

Lab Duration


It will take approximately 1 hour to complete this lab.

Lab Assessment


Test your knowledge on the topics covered in this lab by completing the Lab Assessment. Screenshot assessment items can be found at the end of each exercise and review questions are located on the Review page.

Exercise 1 - Essential Router Configuration


Every computer network has at least one switch where we connect end devices (computers, printers, IP phones, and other devices) and at least one router that represents the main device in a network and connects us to the outside world.
Today, most enterprise networks follow a typical network scheme where they have one central site - headquarter, and a couple of remote sites - branches. For them to communicate, we need a router at each site. Routers usually have 2 interfaces, one connected to a LAN switch and the other to a WAN link. The network connects to the Internet and other remote sites or headquarters over this WAN link.
Routers operate at layer 3 of the TCP/IP and OSI Reference model and have the capability to forward packets from source to destination. Packets travel from the source device over the switch to the router’s LAN interface. The router then forwards the packet to the outside interface based on the destination IP address of the packet. It performs a routing table lookup to find the next hop and exiting interface.
Routing table will be covered in detail in a later module. In this exercise, you will perform basic router configuration.
