Hi Weliem
Taking the exam over RDP or VPN is not technically possible. For the exam, your computer needs to be booted from our Exam environment which is on a bootable USB stick (you are supposed to download the ISO file and place it onto your USB stick). The system boots fully locked and connect to our exam servers.
I am sorry the situation impacted you
