Upgrade Your Cisco Exam Prep: Why GNS3 is the Better Network Tool for IT Students

If you’re studying for Cisco exams, you know about Packet Tracer. It’s a tool for making virtual networks and doing networking stuff. But if you want to make a really top-notch network for your project or exam, you should use GNS3 software on your Mac.

GNS3 is a tool that lets you connect real and virtual devices to make a network. You can create projects that work like real Cisco Routers and Switches. It’s made to give you a more realistic setup for testing networks.
