Event Notifications being able to cross regions would have been helpful, but it's not a correct statement about the Message Service.

Haha, I'm going to go with A and D. Cross-region event notifications? Sign me up! And the consumer types sound about right.

I'm pretty sure the correct answers are B and C. Message Service provides asynchronous notification and the event notification message is retained based on the retry policy.
