Checking unix sys admin skills, how to test your skills?

Question

Career in IT

For a short period of time I have been working as a system administrator for unix systems. I want to test my skills in administration of unix systems, my level is junior. I decided to give myself those tasks:
- create a server with file cleaning on debian
- buy a cheap domain and set up a mail server
- create an nginx web server on it and host a custom WP site
- set up a firewall to connect from only one address (from a working computer to a home )
- configure server backup. If you tell me what is the best way to implement this - I will be grateful
- raise ipsec vpn for a secure connection via ssh

I want to do all this on wsl2 windows, or is it better VB \ VMWare? Maybe it’s worth adding something to your TK to consolidate your skills?
