Ah, the joys of state machine diagrams! This one's a real head-scratcher. I'm going to have to go with C on this one - a trigger is not allowed on the transition to the final state. After all, who needs triggers when you can just teleport straight to the end?

This question is a real state machine brain-teaser! I'm going to have to say that the answer is A. A transition requires a trigger or guard, and this one has neither. Time to brush up on my UML knowledge!

I'm going to have to go with D on this one. A transition is not allowed to leave and enter the same state. Looks like the state machine architect had a case of the Monday's when they drew this up.

Hmm, I'm pretty sure the correct answer is B. A guard condition is not allowed on the initial transition. That's a classic state machine no-no.

This is a tricky one! The diagram is invalid because a transition requires a trigger or guard, and the initial transition has neither. Gotta watch out for those pesky state machine rules.
