Correct Answer: A - Yes You can only attach virtual machines that are in the same location and on the same virtual network as the LB. Virtual machines must have a standard SKU public IP or no public IP. The LB needs to be a standard SKU to accept individual VMs outside an availability set or vmss. VMs do not need to have public IPs but if they do have them they have to be standard SKU. Vms can only be from a single network. When they don’t have a public IP they are assigned an ephemeral IP. Also, when adding them to a backend pool, it doesn’t matter in which status are the VMs. Note: Load balancer and the public IP address SKU must match when you use them with public IP addresses.

One of the few slip-ups from Azure Jesus. The provided answer is correct, the reasoning is correct but missed that VM1 has a basic SKU.

It's valid, because: LB1: Standard SKU VM1: Standard SKU public IP VM2: Standard SKU public IP

I don't understand, it is an internal load balancer, you place your VM behind an internal Load balancer when you do not want to expose them, what is the need of public ip in the first place? some questions are really weird

I think the answer should be no. The load balancer is an internal load balancer and nothing to do with SKU of a public ip is relevant in making the VMs to work.

Correct: YES Tested in lab: no matter LB internal o public, vm in backend can keep their public ip (even if it's no sense in load balancing env...). The only requirement is SKU of public ip: LB standard=>standard PIP LB Basic=>basic PIP Stopped Vm can be added to backend pool The answers to this question could be: -add standard public ip to vm -remove public ip from vm
