What tasks to perform to get a hand in web administration?

Question

PHP

My work activity is related to the administration of local office networks. Recently I went to an interview on the administration of web projects. And although I read the documentation and even accompanied a couple of vds, according to my own feelings, I failed the interview.
As a result, the test task took me instead of the planned 2 whole 10 hours of pure time
.
Please share some tasks on setting up web servers from your recent experience.
In the comments I will give an example of the same test task.

Answer 1

Yes, a whole mountain of tasks. At least for Nginx hosts, it will last for a long time. You have very simple questions there.

Answer 2

Read a Linux book
