Hi Ranger.
My dh has a tech company in Victoria BC. He would not hire someone to work as a network or system admin based on an online course.
Why? In part because the work is hands on. You have to be able to trouble shoot a network from the routers and firewalls through to the desk tops. You have to be able to map a system, build it from the ground up and maintain it. You cannot book learn how to do it. It is hands on work.
His senior sysadmin has a computer science degree, with 12 years of hands on experience.
Both his sysadmins build their own computers and can tear them apart and rebuild them at a moments notice. They can splice cables, rebuild UPS (Uninterrupted Power Supply), program routers, firewalls and managed power bars.
I wish you luck in your field of study, but please make sure you get some hands on experience. Maybe there is a co-op program you can apply to.
