I had to do this while sick and injured...BRUTAL. But this course WILL teach you the working skills of it. Just make sure to know how to set up your computer when you go to work and you're good.

Like guiding through network and security elements ... fast. Challenging and rich in content but not going into too deep. The following courses in the certificate will delve deeper, I imagine.
