Just discovered a number of free network certifications and courses that anyone can take. I believe as a beginner, it is always best to start with a free course rather than hundreds of dollars to the tech giants. You can always opt for the advanced certifications once you have established a solid ground in Network administration / security.
What's best about these courses is that they give you free certificates of completion. And they are recognized institutions that are globally recognized.
Here's the list of courses:
Charles Sturt University - Cisco Certified Network Associate (CCNA) Short course
Coursera - Cisco Networking Basics Specialization
Fortinet - Network Security Associate
Per Scholas - Network Support Certification Track
OpenEdu - Network Security Course
SaylorOrg - Computer Communications and Networks
