In recent years, Cisco has introduced lab type simulation questions into the CCNA exam. Because of this, it is very important these days to have some practice with the actual configuration of a Cisco IOS device before taking the exam. Some people build a home lab for this purpose but this usually costs too much. A popular and more cost effective solution is to use a CCNA virtual lab. Here are 4 factors you need to consider when you choose a Cisco simulator:

1. Lab scenarios - The best CCNA virtual labs out there have simulation functions as well as tutorial functions. These consist of various scenarios which will provide sufficient practice for every feature of Cisco IOS you will need to master for the CCNA. This is an excellent feature, because it's like having your own lab proctor by your side while you do the lab. Do check to see if this is included in your CCNA simulator package.

2. Use together with CCNA books - You should check if the trainer for the Cisco simulator package has any tie-in with certain CCNA books. Often, a particular CCNA virtual lab is designed to work with a series of CCNA books in order to cover both the practical and theoretical aspect of the CCNA. It makes sense to have a more cohesive training package in order to maximize your chances of passing the CCNA.

3. Software revision - Cisco IOS is a very complicated piece of software and the command-line interface is fairly complex. The IOS source code is a highly guarded secret at Cisco. Because of this, it is difficult to write a good simulator and invariably the first version of any simulator will not be able to provide a good simulation. Look for more established simulators with a good track record for the best simulation experience.

4. Price - What is the price of the CCNA virtual lab? Generally the price of a Cisco simulator is quite affordable. Good CCNA virtual labs are available for $150 of less. This is a steal when compared to the cost of setting up your own home lab by purchasing used Cisco switches and routers.
