Ok, here I am - fresh out of my exam ;)
What was the exam like?
Almost the same as the example provided in the brochure:
https://cke.gov.pl/images/_EGZAMIN_ZAWODOWY/informatory/formula_2017/351203.pdf I will try to describe something a bit:
1. Make UTP cable in sequence A to patchpanel and keystone.
2. Configure the router (LAN, WAN, DHCP) and take screenshots on USB.
3. Configure the switch and take screenshots on USB.
4. Ubuntu - find information about the graphics card, processor and disk and make screenshots on USB, additionally enter it into the created table. Additionally, create a hidden folder, change the default opening of photos to a browser, specify the system kernel version, rename the network connection and the computer.
5 Windows - Promote to a domain controller, create a user, add him to a group, change the desktop background to black (that was the hardest part

. Disable the second network interface, rename the active network connection.
6. Connect the Client to the server by means of a switch and router according to the diagram.
7. Make a cost estimate based on the given computer components.
To sum up - there was a lot more paperwork (screenshots, tables, etc.) than the configuration itself. Although I already have some experience in IT, I almost did everything. The exam looks more like the E13 than the E12. As you can see Windows Server has been neglected regarding ADk, which is a plus for me
