Part 5: Configure a Hostname
Part 6: Explore the Rest of the Network
Background / Scenario
The network model in this Packet Tracer Physical Mode (PTPM) activity incorporates many of the
technologies that you can master in Cisco Networking Academy courses. It represents a simplified version of
how a small to medium-sized business network might look.
Most of the devices in the Seward branch office and Warrenton data center are already deployed and
configured. You have just been hired to review the devices and networks deployed. It is not important that you
understand everything you see and do in this activity. Feel free to explore the network on your own. If you
wish to proceed more systematically, follow the steps below. Answer the questions to the best of your ability.
Note: This activity opens in and focuses on mode. Many of the Packet Tracer activities you Physical
encounter in Cisco Networking Academy courses will use mode. You can switch between these Logical
modes at any time to compare the differences by clicking the (Shift+L) and (Shift+P) Logical Physical
buttons. However, in other activities in this course you may be locked out of one mode or the other.
