What is CCNA?

The Cisco Certified Network Associate (CCNA) is an entry-level credential to validate essential networking knowledge and skills. It is designed for beginners and professionals looking to build a strong foundation in managing and troubleshooting modern networks.

It covers key areas such as network fundamentals, routing and switching, Internet Protocol (IP) services, security basics, wireless concepts, and automation. It is widely recognised by employers and often used as the first step toward more advanced Cisco certifications and networking careers.

CCNA Examination Details

Although there are no official prerequisites, candidates with a strong background in Information Technology (IT) are often better prepared. Having some hands-on experience and foundational knowledge can make it easier to understand the concepts. Below are some commonly preferred skills and experience areas for candidates but it is not mandatory:

a) A minimum of one year of experience in using and working with Cisco products

b) Foundational knowledge of IP addressing

c) In-depth knowledge of network fundamentals

Exam Registration

To take the CCNA exam, you need to register through the official Cisco Certification website or authorised testing centres. The registration process typically involves creating an account, providing personal information, selecting the exam track, and paying the fee. Once registered, you can schedule your exam at a convenient time and location.

CCNA Exam Topics and Weightage

The Cisco Certified Network Associate exam is a 120-minute exam which covers a wide range of topics and evaluates an individual's knowledge and skills in networking technologies. Here are the key components or mainly focused topics of the exam and their weightage:

1) Network Fundamentals (20%): This domain covers foundational networking concepts, including network components, network topologies, IPv4 and IPv6 addressing, wireless principles, virtualisation fundamentals, and TCP and UDP.

2) Network Access (20%): Network Access focuses on switching and wireless networking concepts. It includes VLANs, trunking, Layer 2 discovery protocols, EtherChannel, Rapid PVST+, wireless architectures, and device management access.

3) IP Connectivity (25%): As the largest exam domain, IP Connectivity assesses routing concepts and configuration. It covers routing tables, IPv4 and IPv6 static routing, single-area OSPFv2, first-hop redundancy protocols, and route selection.

4) IP Services (10%): This section covers common network services such as Network Address Translation (NAT), Network Time Protocol (NTP), Dynamic Host Configuration Protocol (DHCP), Domain Name System (DNS), Simple Network Management Protocol (SNMP), syslog, Quality of Service (QoS), and Secure Shell (SSH).

5) Security Fundamentals (15%): Security Fundamentals evaluate knowledge of common security threats, vulnerabilities and mitigation techniques. It also includes device access control, password policies, Access Control Lists (ACLs), Layer 2 security features, wireless security protocols, and basic security concepts.

6) Automation and Programmability (10%): This domain introduces modern network automation and controller-based networking concepts. It includes traditional versus controller-based networking, REST APIs, JSON data, configuration management tools, and the role of automation, Artificial Intelligence (AI), and Machine Learning (ML) in network operations.
