This does not match the physical testing I have been doing and my father has said the same about having issues with DND and the clock.

So, I don’t really know what’s going on, then. But unless vibrate and DND is turned off and the volume is all the way up, sometimes the alarm just doesn’t work and I have missed stuff before.

Android was really clear about this: there was just “no notifications”, “alarm only” and “all notifications”. I wish Apple would make a three state toggle like this and bundle it all together ..

(I understand that you’re trying to tell me that alarm should be working, but it just isn’t).

The alarm app on iOS can run into an issue where it will not play sound regardless of any other setting. It has existed in many versions of iOS. It has happened in iOS 10 and iOS 11, I don't know about the previous versions.

They fix is to reboot the phone.

I cannot trust it for critical alarms, so a simple device by the bed is required again.
