Just to clarify, all resources are in the same region, right?

That's what I thought too, but I guess it depends on the setup.

Wait, are you sure? I thought each subscription needed its own circuit.

You only need 1 ExpressRoute circuit for multiple subscriptions.

I feel like I read that you can connect multiple subscriptions to a single ExpressRoute circuit, but I’m not confident about the exact number required here.

I practiced a similar question where we had to connect multiple subscriptions, and I think it was just one circuit needed if they were in the same region.

I think we might need at least two circuits since we have multiple subscriptions, but I can't recall if one can cover all of them.

I remember something about ExpressRoute circuits being shared across subscriptions, but I'm not sure how many we actually need for three subscriptions.

Okay, I think I've got a handle on this. The key is to find a way to logically separate the Windows and SUN hosts so they can access the storage they need without interfering with each other. I'll carefully consider the options and try to eliminate the less suitable ones.

The CAN-SPAM Act... I know I learned about that in class, but the details are escaping me right now. I better read through the question again and see if I can figure it out.

If I recall correctly, disaster recovery instances have specific limitations. That could be another reason for the operation to fail.
