Looks like a compilation error due to push_back.

Okay, I think I've got this. The key is to use a virtual network with a single subnet and a standard Azure load balancer. That way, the VMs will be able to fail over quickly and maintain existing connections. Option B looks like the way to go here.

Easy peasy! The question states the website is hosted on EC2 instances behind an Application Load Balancer, so the answer has to be B. We use an A record to point the zone apex to the IP address of the load balancer.
