Typical work environment

Network administrators typically work in an office in the IT department of a corporation. They spend their day responding to time-sensitive emails and voicemails from coworkers. Network administrators monitor the computer network to make sure everything is working as it should. They visit with employees with technical issues and troubleshoot the problem. They also order and install new computer hardware. Some network administrators may work on-call after hours in case of technical emergencies. Most network administrators work forty hours a week or more.   

Typical hours

The typical work hours in an office setting for a network administrator are usually from 9 AM to 5 PM. Extra work hours may be necessary to troubleshoot issues with a particular system.

Available certifications

Most network administrators begin with a bachelor’s degree in computer science or a related field. Certifications beyond a bachelor’s degree exist to help you stand out from the crowd and land a higher salary.

  • CompTIA Network+ Certification. This vendor-neutral certification validates the skills needed to establish, maintain, and troubleshoot networks on any platform.

Career path

A network administrator must have a bachelor’s degree in computer science or a related field. It’s also helpful to pursue internships in the IT departments of tech companies or other businesses while in college.

Troubleshooting and logical thinking skills are essential for a successful network administrator because they’ll have to quickly think through the possible causes and potential solutions to network issues. Also, network administrators are often called upon to recall technical facts related to the platforms their organizations use.

Obtaining professional certifications like CompTIA Network+, Cisco Certified Network Associate, Cisco Certified Network Professional, SolarWinds Certified Professional, Microsoft Certified Solutions Associate, or the various Oracle certifications is vital for any network administrator.

It’s always crucial for a network administrator to stay up on the latest trends. According to the tech company Cisco, the move to 5G technology is one trend network administrators must be aware of in the coming years. 5G is the fifth generation of cellular technology, designed to increase the speed and flexibility of wireless services.

The increasing size of the Internet of Things (IoT) is another trend network administrators should follow. More and more objects are becoming “smart” and connecting to computer networks to communicate with other objects and people. Some industry analysts think IoT could be a transformative, permanent paradigm shift.

Also, more network administrators will be called upon to develop their soft skills in the coming years. Network administrators have to interact with people at all levels of an organization. That means they have to communicate complicated ideas to people who may not have a great deal of technical expertise.
