Correct Answer: Basic Load Balancer: Backend pool endpoints for Virtual machines in a single availability set or virtual machine scale set. Subnet12 association will be used to assign an IP for the internal load balancer, not to load balance the VMs in the Subnet. Box 1: Yes VM1 and VM are in the Availability Set. Box 2: No Both VMs are not part of any Availability Set or Scale Set. Box 3: No Both VMs are not part of any Availability Set or Scale Set.

Correct my friend! "They are the machines or services that create a backend pool. The Basic Tier is quite limiting. It can only have a single availability set, virtual machine scale set or a single machine. The Standard Tier can span any virtual machine in a single virtual network which includes blends of scale sets, availability sets, and machines."

FYI - for standard load balancer, VMs must be in the same vNET and for Basic, they must be in an availability set.

LB1 is in subnet 12 NOT in subnet 11. Now VM1 & 2 are in single availability set but they are in subnet 11 So how can LB1 sitting in subnet 12 can balance the traffic among VM1 & 2 ? VM3 & 4 are in subnet 11 with no availability set. VM5 & 6 are in subnet 12 but without availability set. So in my opinion answer is "No" for all 3 conditions. Where am I wrong and why?

An internal load balancer enables the following types of load balancing: Within a virtual network. Load balancing from VMs in the virtual network to a set of VMs that reside within the same virtual network. https://learn.microsoft.com/en-us/training/modules/configure-azure-load-balancer/4-implement-internal Note that it mentions *within the same virtual network*, not *within the same subnet*.
