A degree in IT, computer science, or other related fields might not always be required in network administrator jobs; however, it can help you stand out in the job market, and in some cases, make career development easier. If you want other means to gain knowledge and skills in this line of work, establishing a strong technical background is fundamental. You then need to acquire the right certifications for the kind of roles you want or the employer you wish to work with. From there, you can work on building experience and honing your skills for further opportunities.
