A Multiple NICs allow a VM to connect to different subnets. VM must have at least one NIC. A virtual machine can have more than one NIC, depending on the size of the VM you create. Each NIC attached to a VM must exist in the same location and subscription as the VM. Each NIC must be connected to a VNet that exists in the same Azure location and subscription as the NIC.

Yes. Remember you goal! "You need to create a new network interface named NIC2 for VM1." You can pretty much ignore everything expect for the location of VM1. The question only asked if you can create a new NIC for VM1 in westus not if you can connect it to any subnets or vNets. "Each NIC attached to a VM must exist in the same location and subscription as the VM. Each NIC must be connected to a VNet that exists in the same Azure location and subscription as the NIC. You can change the subnet a VM is connected to after it's created. You can't change the virtual network. Each NIC attached to a VM is assigned a MAC address that doesn't change until the VM is deleted." https://learn.microsoft.com/en-us/azure/virtual-network/network-overview#network-interfaces

I've also tested it in a lab to see if NIC 2 being in a different resource group will affect the ability of a VM to use that NIC. VMs can use NICs in another RG without any issues.

Answer: A The resource group the NIC is created in does not matter. What matters is the region the NIC is connected to. NIC's attached to VM's must be located in the same region as the VNET/Subnet it is connected to. The NIC must also be created in the same subscription. Multiple NICs allow a VM to connect to different subnets. VM must have at least one NIC. A virtual machine can have more than one NIC, depending on the size of the VM you create. Each NIC attached to a VM must exist in the same Region and belong to the same subscription as the VM. Each NIC must be connected to a VNet that exists in the same Azure Region and belong to the same Subscription as the NIC.

A is the answer. https://learn.microsoft.com/en-us/azure/virtual-network/virtual-network-network-interface?tabs=network-interface-portal#create-a-network-interface - A network interface can exist in the same, or different resource group, than the virtual machine you attach it to, or the virtual network you connect it to. - The virtual machine you add the network interface to must also exist in the same location and subscription as the network interface.

Hello guys, in this kind of questions I guess the clue is the following: VM1 connected to VNET2 with NIC1 on location West US. Then VNET2 location is West US and only the NICs on West US locations will be ok for the answers.

Makes no sense at all, what region is NIC 1 in? A vm can only have 1 NIC at a time I thought!?

I believe the answer wants to stress that they belong to the same region (and the fact the Resource Group is different is irrelevant)

What you need to remind in this type of questions that resource group is global resource and doesn`t belong to any region even if it is getting region tag where it was created :) It is one of the most confusing things in Azure and this is why you will see a lot of questions about it :)
