Proficient certifications are crucial in the IT world, where practiced abilities and techniques are needed. Because job roles demand more than work expertise, the applicant is thoroughly trained and can address the latest technologies. One of these certifications is CCNA. This post is all about why CCNA certification is great.

What is CCNA?

CCNA is Cisco certified network associate. It is a kind of professional certification given by Cisco for networking experts. It is created to develop, improve and assess the networking experience of an individual. The certification accredits the holder's overall capability to install, defend, manage, and troubleshoot problems within company networks. It allows learners to keep up-to-date with their current abilities and knowledge. The credential enhances job chances in the networking world. It also helps learners develop their careers in various fields, including cybersecurity.

It confirms that the individual learner can manage even the most complicated and challenging networking systems. Moreover, the certificate holder is ready to readjust the practical environment in all kinds of IT companies despite their operating ranges.

The CCNA has grown into the most in-demand IT networking certificate. This certificate is developed to strengthen core logical skills and problem-solving abilities expected to work within IT and networking. Holding one proves that the learners have the appropriate skill sets to maintain the status of various networking job positions, such as network engineer, support engineer, network system administrator. Of course, it won't satisfy learners who crave to exceed their rivals, but the certificate guarantees that they are on the correct path.

There is no specific qualification for the exam that implies that users do not have to go for any previous test before being qualified as CCNA-certified. However, if learners possess some knowledge in the IT field and desire to begin their profession in the networking domain, then this certification is ideal.

What does CCNA cover?

The Cisco Certified Networking Associate certification is the ideal starting point for beginners and network engineers looking to improve their essential networking awareness. After getting this certification, learners become experts in installing, configuring, troubleshooting, operating LAN/ WAN and dial access services. They completely understand how to explain the process of data networks, perform an IP addressing system, fix networking requests with shifted LAN technology, and everything about seven network layers. Those who work as system engineers, domain specialists, network administrators profit hugely from this.

Some of the most crucial abilities that CCNA covers are:

  • Performing an IP addressing design
  • Fixing network security difficulties with switched LAN methods
  • Describing the procedure of data networks
  • Practice on the seven network layers
  • Discovering how to perform routing and switching
  • Security basics

The CCNA certification remains legitimate and valid for three years. The exam is a 120-minute. It examines learners' understanding and abilities associated with network basics, network access, IP connectivity, IP services, security basics, automation, and programmability.

The following topics are standard guidelines for the exam:

  • Network Fundamentals -20%: This section covers various topics like routers, switches, and access points. It also includes network topology structures, environmental interfaces and cabling standards; IPv4 and IPv6 arrangement; IP parameters; wireless, virtualization, and switching details.

  • Network Access- 20%: The network access section covers various topics such as configuring and testing VLANs, inter-switch linking, Layer 2 device customs, and EtherChannel; Rapid Spanning Tree Protocol services; Cisco wireless structures, AP methods, environmental WLAN elements, AP and WLC administration access links, and wireless LAN access.

  • IP Connectivity - 25%: This section covers topics such as routing tables, IPv4 and IPv6 static routing, OSPFv2; and redundancy rules.

  • IP Services - 10%: This section covers details such as how to configure and verify NAT and NTP; how to define DHCP, DNS, SNMP, and Syslog characteristics; per-hop management; utilizing SSH; reporting TFTP/FTP.

  • Security Fundamentals - 15%: This section includes security details like threats and how to mitigate, dynamic access control; password management; access control panels; Layer 2 security characteristics; wireless security rules.

  • Automation and Programmability- 10%: This final section covers connecting established networks with controller-based networks, automation topics, and interpreting JSON data.

In other words, the CCNA certification exam includes three essential topics: networking, security, and automation. In this, topics linked to network basics might need learners to describe the purpose and use of network elements, for example, and explain the features of various network topology designs. For example, learners might be asked to configure and establish VLANs or configure the elements of a wireless LAN access for connectivity.

Parts on security basics cover matters such as:

  • Establishing important security ideas.
  • Setting device access controllers by utilizing local passwords.
  • Placing Layer 2 security characteristics like DHCP snooping, powerful ARP review, and port safety.
  • Configuring and testing access control panels.

In the Automation and Programmability section, learners should be ready to connect established networks with controller-based networking. In addition, some questions might require candidates to explain the features of REST-based APIs and identify configuration administration devices' capacities.

Job-roles After Getting CCNA Certification

  • System Engineers: The main duty of a system engineer is to connect and maintain various devices (systems) in a company. That may involve various hardware devices, routers, switches, or other devices used.

  • Support Engineer: The job responsibilities involve doing meticulous analysis, recognizing, troubleshooting, and fixing client problems promptly.

  • Network Administrator: This is one of the most sought-after job positions in the networking area. The role includes planning, executing, managing, and maintaining a firm's network.

  • Network Security Associate: It includes implementing necessary security vulnerability assessments tools to recognize security threats.

  • Network Analyst: A network analyst is also accountable for the connection, settings and installation, design, support, and analysis of network elements in a firm. It is one of the fastest-growing IT businesses due to the stability and diversity in the areas they work for.


The CCNA certification is widely recognized in many countries around the world. The certificate can give its holders a good job and a pay scale than those who don't hold this certificate. More all-embracing CCNA job positions have been available in the market in recent times. For a learner to get one job, it is qualification proof that they hold the CCNA.
