I think the #4 is should be "Less than" only, because you don't want to trigger the Scale up and Scale down at the same time.

I believe the answers are: 1st box: as given, since we're analyzing the state of messages in the Service Bus Queue 2nd box: as given, because Active Message Count will show us just the count of messages that are in the active state and ready for delivery, while Message Count would show us all the messages. 3rd box: Average, since we should stay consistent with the Scale Up time grain, which is also "Average" - this way, when we use "average" on both, we have consistent and clear conditions when to go up and when to go down

I think the 3rd option should be "Average" since the scale up rule is based off average, it makes sense to make the scale down rule work on the same principal.

The image is cut so i cant see the bottom 2 dropdowns but they sound alright in the answer explanation bellow. Also the 2nd box should be Message Count. Reason: In the question it is said: "when the average queue length of unprocessed AND valid queue messages" If it was just valid Queue messages it would have been enough to set it on Active Message Count... but they want Valid AND Unproscessed messages... so i think it should be Message Count. (i am not 100% sure but unprosessed message should not count as an active message)

Messagecount is false because it also contains deadlettered messages among others. Unprocessed messages are active because they are "ready to delivery". So i think "Active Message Count" is correct
