Lab 02 — Centralized DHCP with Relay Agents
Three sites joined by /30 point-to-point links. Miami and New York have no local DHCP server: each city router relays DHCP requests across the WAN to a server in the data center. Covers DORA, giaddr, scopes, static routing, and a real troubleshooting log.

Lab 03 — Troubleshooting Speed Run: “I Can’t Reach the Website”
A user cannot open a website, but a coworker can. Download the Packet Tracer file, skip the setup, and work the fault from the bottom up: link, IP config, gateway, routed path, name resolution. Each step shows the command, why it is run, what healthy looks like, and what a different result means.
