You can take your certification preparation up a notch and gain first-hand experience using NetSim Network Simulator. You will get the hands-on experience you need to complete your certification through guided labs.
What is NetSim?
NetSim simulates Cisco Systems’ network hardware and software. It will give you hands-on experience in configuring protocols and entering commands to pass your certification exam.
NetSim includes guided labs that cover the topics required for the certification exam. These labs are preconfigured to help you understand and master the skills required to complete your certification. NetSim is now available online. You can use it as soon as you open your web browser.

What makes NetSim so special?
NetSim stands out from all other products on the market due to its unique functionality and features. Multiple routing protocols are supported, as well as a wide range of Cisco(r), routers and switches.
Labs in NetSim only require the functionality and devices included with NetSim. They do not require access any external router or switch hardware. NetSim supports many of the IOS commands that are available on physical routers or switches, but not all. NetSim supports all commands listed in the available labs.

How can I use NetSim for certification preparation?
NetSim’s primary purpose is to help you understand the concepts and then to actually implement routing on Cisco devices. It allows you to compare your configuration with the expected. This helps you identify mistakes and points you in the right direction.
Two fundamental tasks are required to master Cisco networking: learn the theory of routers, switches, and then get hands-on experience implementing that theory by configuring devices in a network and testing them out in a lab environment.
It can be difficult to self-study for certification. It is difficult to learn the vast amount of information required for CCNA candidates and the required skills. You can either read a reference book or consult an instructor to learn the basics of configuring a network. However, just reading a book won’t give you the practical experience of routing or switching that NetSim can provide. This will allow you to build on the theoretical knowledge that you have.

What about NetSim online,
NetSim is now accessible on almost any internet-connected device, including smartphones, tablets and laptops. The NetSim online apps are easy to use. There is no need to download, install, or set up. This uses a smaller amount of system resources than the desktop version and you can begin working in the labs right away. NetSim online allows you to receive instant updates, so you can always work with the most current material.

Boson NetSim Network Simulator offers the most comprehensive product available for learning how to configure Cisco routers and switches. NetSim will help you not only become certified but also give you the skills, knowledge, and confidence you need to do the job.
