Overview What You Will Learn Curriculum Instructor

Lab Description

In this lab, you are placed in the role of a network troubleshooter responding to user reports about website access issues in an office environment. Your investigation begins with launching Wireshark to capture and analyze traffic from the network segment.

You’ll start by inspecting ARP (Address Resolution Protocol) traffic and will notice an abnormal number of requests, leading you to suspect and confirm an ARP-Storm attack that could be disrupting communication. Next, your focus shifts to DNS traffic, where you ensure that domain name resolutions are occurring properly and that the DNS server is operating without errors. Lastly, you utilize ICMP ping traffic to evaluate connectivity to multiple devices on the network, identifying those that are unresponsive and may be contributing to the issue.

Through structured analysis of ARP, DNS, and ICMP protocols, this lab teaches you how to detect misconfigurations, attacks, and failures in network communication paths. You’ll gain hands-on experience in protocol-level troubleshooting and enhance your ability to interpret network behavior using real packet captures.
