Cisco is one of the leading information technology, and networking companies in the world and that makes them so big and special that their devices need special training in order the be handled. Cisco has created three courses, and they are CCNA(Cisco Certified Network Associate), CCNP(Cisco Certified Network Professional) and CCIE(Cisco Certified Internetwork Expert) and each course will allow you deal with different parts of networking. With CCNA being the essential course that is needed to get any of the other two.
CCNA is the basic course, this course will get you some understanding of what is needed to have a functional network, but one thing that it will not teach is how to make a network "airtight". However, that is not the main objective of the course, for that they have created the CCNP.
CCNP will focus on cloud, data centre, security, wireless, routing snd switching and service provider. With this course will make the understanding of data and network security much more profound and intense that the student should be able to understand the complexity of any type of security.
In other words, CCNP is an essential course to have when your main focus is to work with security. this course will not only teach you the protocols but how to work them, how to make the network safer making it double-check every step and always verifying the authenticity of every request that is made.
