Cisco Packet Tracer is a network simulation tool that allows you to practice networking, IoT, and cybersecurity skills in a virtual lab – no hardware needed. It is a free tool for certification exam preparation, particularly for CCNA students. You can create and configure your own labs, visualize how a network works, and integrate IoT devices, Python code, or network automation. You can download Packet Tracer by enrolling in one of the three self-paced courses offered by Cisco Networking Academy. You can also find alternative lab solutions such as Cisco Learning Labs and Cisco Modeling Labs.

Some of the features of Packet Tracer are:

• It allows you to create network topologies or simulate your existing network.
• You can add network devices and connect them with cables or wireless links.
• You can also configure your devices and test their communication.
• You can practice building simple and complex networks, visualize how a network works, practice rack, stack, and cabling skills in the virtual lab, integrate IoT devices, Python code, or network automation.
• You can collaborate and compete within Packet Tracer, share network designs for feedback, and connect with the global Facebook community.
• You can choose between real-time mode and simulation mode to envision the network behavior.
• You can use Packet Tracer on various platforms, such as Windows, Linux, and Android.
• You can use Packet Tracer in any language as it supports international language input.
• You can use Packet Tracer to learn about most networking protocols, such as STP, HSRP, RIP, OSPF, EIGRP, BGP, HTTP, DNS, etc.
• You can use Packet Tracer in an interactive environment where you can add notes, control time intervals, and customize single or multi-user activities.

I am using Jeremy's IT Lab's Packet Tracer Labs are a series of free and interactive lab exercises that run on the Packet Tracer software. They are designed to help you learn and practice the topics covered in Jeremy’s IT Lab’s CCNA and CCNP courses on YouTube. You can access the labs by signing up for Jeremy’s IT Lab’s email list or by visiting his website. The labs cover various topics such as switching, routing, wireless, security, IoT, etc. They also include flashcards and quizzes to test your knowledge. You can also find other Packet Tracer labs from different sources online. These labs help teach the protocols that are on the CCNA exam such as:

• Ethernet
• IP
• TCP
