I'm not sure where one goes in the AWS web interface to view these icons. Poking around the EC2 menus for a while, I don't see an icon anywhere.
I wouldn't say the icons are _good_, but I wonder if part of the reason the quiz is so hard is that Amazon doesn't really care if you know what the icons mean anyway. Seems like they're mostly used for branding and marketing, not anything users will see regularly.
If you click the pushpin icon in the web interface, you'll get a dropdown with the services and their icons. You can drag icons into your top bar as shortcuts.
