Frequently asked questions

CCNA stands for Cisco Certified Network Associate, which is a certification you can earn after taking the 120-minute exam administered by Cisco. The exam tests your knowledge and skills related to network fundamentals, network access, IP connectivity, IP services, security fundamentals, and automation and programmability. Once you earn your CCNA, you can use it to get a job in the information technology (IT) or networking fields. For example, you could work as a Cloud Engineer, Network Administrator, Systems Administrator, or IT Manager. You can also take additional specialized exams to land a more specialized role. If you complete the CCNA Routing and Switching Certification, for example, you are eligible for positions like a Network Analyst or Network Engineer.

Many people pass the CCNA exam through self-study using the latest learning materials supplemented with practical instruction. The exam covers a broad range of basic and modern networking concepts along with real-world Cisco network configuration scenarios. It’s important to both understand the concepts and practice applying them. Simulated configuration exercises, practice labs, and sample test questions are especially helpful in preparing for the CCNA exam. Udemy courses can help you master the networking concepts and skills needed. You can also gain hands-on Cisco CCNA configuration and troubleshooting experience through practice labs.

The CCNA exam tests your knowledge and skills in networking fundamentals such as routing and switching, network access, IP connectivity, IP services, security basics, and automation and programmability. Among the topics covered are how to build simple LANs, how to use a patch panel, troubleshooting routers and switches, IP addressing and subnetting, IPv6 routing, address allocation using Dynamic Host Configuration Protocol (DHCP), access control lists (ACLs), basic WAN technologies such as VPN and Multiprotocol Label Switching (MPLS), external authentication methods, quality of service (QoS), IP services such as Network Address Translation (NAT). For many years, the CCNA certification involved multiple exams for individual tracks like CCNA Voice and CCNA Data Center. In 2020, Cisco combined all the tracks into one comprehensive CCNA exam based on the latest networking technologies, software development skills, and IT job roles, including network administrator and network engineer.

Although there are no formal prerequisites for CCNA certification, most professionals in the field would recommend a thorough understanding of the CCNA topics before taking the exam. A lot of CCNA candidates have one or more years of experience implementing Cisco solutions along with a grasp of basic IP addressing and network concepts.

No, the CCNA is no longer required before you can attain a CCNP or higher-level Cisco certification. However, you need a certain level of competency and knowledge that builds upon skills attained at the CCNA level before you should attempt the CCNP certification. To achieve any of the Cisco professional-level certifications, you must pass two exams. You can earn a CCNP certification in one or more of the following specialties: enterprise (including routing, switching, and wireless networking), collaboration, security, data center, and service provider. Cisco also offers professional-level certifications in Cisco Certified DevNet Professional, which proves your skills in developing and maintaining applications built on Cisco networks, and Cisco Certified CyberOps Professional, which proves your skills in incident response, cloud security, and other active defense security roles.

Cisco has associate (CCNA), professional (CCNP), and expert (CCIE) certifications. These include the CCNA, Cisco Certified CyberOps Associate (entry security analyst skills), and Cisco Certified DevNet Associate (developing apps on Cisco platforms). CCNP certifications in enterprise (routing, switching, and wireless), collaboration (Cisco apps and services), data center (Cisco infrastructure), security (Cisco security solutions), and service provider (implementing and operating Cisco solutions), along with Cisco Certified CyberOps Professional and Cisco Certified DevNet Professional; CCIE certifications in enterprise infrastructure (operating Cisco solutions for complex setups), enterprise wireless (operating Cisco solutions for complex setups), data center (building and operating Cisco data center solutions), security (implementing Cisco security solutions), service provider (implementing Cisco service provider solutions); and design expert to prepare you for designing large networks.
