Trending @Accenture; Need help.

Yes you can

Yes, you can. I did the same. Just close all the apps (teams, outlook, etc.)

I don't think you can give now as accenture has recently blocked the some firewall setting. I tried 2 months back and it won't allow you. Arrange another laptop . While giving aws exam it will give you security warning and your system compatibility will fail at firewall point.

Not recommended. You might face issues due to certain monitoring requirements for the exam.
