At present, the official examination fee of Cisco CCNA is 2250 yuan, and the training fee is more than RMB 1000. At present, whether you are a system integration engineer, a network security administrator or anything else, you need a Cisco certificate as long as you are networked.

At present, there are well-known trainings, such as Tom's ITAA. If you want to learn, you can consider taking part in such training or consultation.

It is suggested that we should not only learn from Cisco's CCNA, but also consider CCNP CCIE or turn to safety, which are the general trend in the future.

In addition, the most important thing to learn from Cisco is to pay attention to experiments. If you want to learn Cisco, you must look at the equipment. Large-scale network engineer training has a very good network environment. The router must be at least 2600 series and switch 3500.
