Course description

Who is a Network Administrator?


A network administrator is an information technology (IT) professional. Their job is to secure, maintain, and troubleshoot computer networks, which are groups of computers that share information. Organizations use network administrators to ensure that their networks are running efficiently and meeting business requirements.

 

What does a network administrator do?


Duties of a network administrator include:


Install, configure, and maintain network hardware and software such as routers, firewalls, and switches
To protect networks from unauthorized users by physical and technical means
Set up and secure virtual private networks (VPNs).
Troubleshoot network connectivity issues for other employees
Maintain and troubleshoot storage networks
Network administrator job descriptions are often similar to system administrators.


What is CCNA certification?


Cisco Certified Network Associate (CCNA) is a technical Certification that Cisco offers for early-career networking professionals. It covers the following topics:

 

Network fundamentals
Network access
Internet Protocol (IP) connectivity
IP services
Security fundamentals
Automation and programmability


Cisco made significant changes to its exam structure on Feb. 24, 2020, putting a focus on simplifying it and making it more flexible. It also attempted to align the exam more closely with modern industry needs. Previously, Cisco offered several CCNAs for different networking specialties. The latest update consolidated those offerings into one CCNA certification, which is now the foundational certification for all Cisco-based career paths.
