CCNA (Cisco Certified Network Associate) All you need to know
Even if you’re not necessarily looking to get into networking itself, the IT field in general, you do need networking knowledge to secure networks. You have to have some understanding of networks. To be able to hack a network, you need to understand the network. To operate servers which run over networks, you should understand those networks. And the best way to start to learn about networking is the CCNA.
What Is The CCNA Certification?
The CCNA—which stands for Cisco Certified Network Associate—is an entry-level information technology (IT) certification issued by networking hardware company Cisco. The CCNA is designed to validate your knowledge on fundamental networking concepts often requested in networking roles in IT positions.
Here’s a quick rundown of key facts:
- To get the CCNA certification you’ll have to pass one exam, the 200-301 CCNA.
- Taking the CCNA exam costs $300, plus tax.
- There are no prerequisites to take the exam, but training and some experience with computer networks are recommended.
- The expiry of CCNA Certification is three years. Renewal requires certification holders to register for and pass the same or higher level Cisco recertification exam(s) every three years.
