You plan to create six virtual machines and to load balancer requests to the virtual machines. Each load balancer will load balance three virtual machines.
You need to create the virtual machines for the planned solution.
How should you create the virtual machines? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
Answer: 
Explanation:
Box 1: be created in the same availability set or virtual machine scale set.
The Basic tier is quite restrictive. A load balancer is restricted to a single availability set, virtual machine scale set, or a single machine.
Box 2: be connected to the same virtual network
The Standard tier can span any virtual machine in a single virtual network, including blends of scale sets, availability sets, and machines.
