What is the CCNA?
CCNA stands for the Cisco Certified Network Associate and is given to those students who have demonstrated their understanding and skill in the ability of installing, configuring, operating, and troubleshooting routed and switched networks, which also includes how to implement and verify connections of remotes sites in wide area networks (WANS).
This certification also introduces the basics of understanding security threats, as well as the introduction to wireless networking, wireless terminology, and Internet protocol such as IP, gateway routing, VLANS, Ethernet, and access control lists. There are three different tests that students can take -
640-802 CCNA Exam - The full exam, which includes both parts of interconnecting Cisco networking devices.
640-802 ICND 1 Exam - The first half of the complete CCNA exams that students will take in regards to learning about the interconnecting devices for Cisco networking
640-802 ICND 2 Exam - The second half of the complete CCNA exams that students take in regards to Cisco networking devices.
Students can either take the entire CCNA exam or split them in to the first and second halves of the ICND. There are no Cisco prerequisites for individuals to take this exam, however basic knowledge of computers and the internet is a must.
To further this knowledge, receivers of the CCNA can go on to test for the CCNA Security certification, which tests the knowledge and skills of students in dealing with the security of Cisco networks.
