CCNA is an information technology certification from Cisco Systems, the world’s leading networking hardware manufacturer. It is an associate-level certification that provides a solid foundation for pursuing higher-level IT certifications.
IT professionals often pursue professional certifications as a way to validate their skills. The following guide will help you understand what CCNA is and how to get this credential.
Networking Fundamentals
CCNA is an excellent starter certification that will help you gain entry into the IT field. It will also serve as a springboard to higher-level Cisco exams.
Moreover, the knowledge you obtain through this program will help you understand how networking equipment works and how to configure it. This will allow you to work efficiently and effectively in a network environment.
A network is a group of interconnected devices that share resources such as data storage, applications, email, printers, etc. This is done by flowing network packets. These packets contain information such as source, destination and a header.
Moreover, these networks can be public, private or extranet. The largest network is Internet, a huge global internetwork that connects multiple networks. There are a variety of services available on the Internet such as governmental, academic and corporate. An example of an extranet is an organization’s website. An enterprise private network (EPN) is a type of computer network used by a company.

Routing and Switching
As a beginner-friendly certification, CCNA is an excellent option for new network technicians. Cisco designed the exam to validate all the knowledge a networking professional learns in their first year on the job.
But you should still study and practice for the test. Find free tests online and try them at least once a week to hone your skills and get ready.
The CCNA exam covers topics like LAN/WAN and TCP/IP paradigm, switches and routers, network utilities (ping, tracert, arp), IP addressing and subnetting, VLANs and trunking, and routing protocols (OSPF, EIGRP, and BGP). The certification is more in-depth than the CompTIA Network+ credential. The latter is vendor-neutral and prepares you to work with any networking technology or tools, but CCNA only covers Cisco products and solutions.
Wireless Networking
As wireless technologies have become increasingly common, companies require more and more network engineers who are familiar with the technology. The CCNA Wireless certification helps you build your expertise to service and support wireless networks using Cisco equipment.
You’ll learn the fundamentals of wireless networking as you configure and verify access control list configuration and operation. You’ll also learn how to troubleshoot issues related to wireless LANs, including wireless security basics, WPA/WPA2 with personal mode and rogue SSID broadcast containment.
Although a bachelor’s degree is not a prerequisite for this exam, having an academic background in computer networking or IT can help you prepare and pass the test more easily. Taking a brief, preliminary course on the subject can also prove beneficial, since it will give you a good understanding of the subjects tested in the CCNA exam. In addition, some employers may let you use company-provided training expenses to take the exam. Self-study with textbooks and online courses is another popular method for preparing for the exam, as there are several high-quality resources on the Internet and tools like GNS3 or Packet Tracer that enable you to study without the need for expensive equipment.
Security
The CCNA certification recognizes basic skills for installing, supporting and troubleshooting wired and wireless networks. The credential is available for several solution tracks: Cloud, Collaboration, Cyber Ops, Data Center, Industrial, Routing and Switching, Security, Service Provider and Wireless. Depending on the solution track, candidates must take one or two exams.
Getting a CCNA certification is an important step for IT professionals who want to boost their career prospects. It shows that their expertise and knowledge of Cisco networking technology is recognized by the company itself.
Although there are no formal prerequisites for earning a CCNA, it is best to have an academic background in computer science or IT, or at least some brief preliminary courses. It is also helpful to have both theoretical and practical knowledge of the technologies in order to prepare for the exam and apply them in real-world situations when working with networking devices and systems. If you’re considering taking a CCNA exam, there are many online training and self-study packages available that can help you get ready.
