Assessment Objectives

• Part 1: Build the Network
• Part 2: Configure Initial Device Settings
• Part 3: Configure Network Infrastructure Settings (VLANs, Trunking, EtherChannel)
• Part 4: Configure Host Support

Introduction

In this Packet Tracer Skills Assessment (PTSA) you will configure the devices in a small network. You must configure a router, two switches, and two PCs to support both IPv4 and IPv6 connectivity. Your router and switches must also be managed securely. You will configure inter-VLAN routing, DHCP, Etherchannel, and port-security.
All of your tasks will be performed in PT Physical Mode. You will not be able to access the logical topology for this assessment. Network devices must be configured from a direct console connection.

Instructions

Part 1: Build the Network

• a. Move the required devices into the equipment rack.
• b. Place the PCs on the table.
• c. Connect the devices according to the topology diagram.
• Use Copper Straight-Through cable to connect all devices
