Suggested Answer:

Box 1: 6 -
Two out of three update domains would be available, each with at least 3 VMs.
An update domain is a group of VMs and underlying physical hardware that can be rebooted at the same time.
As you create VMs within an availability set, the Azure platform automatically distributes your VMs across these update domains. This approach ensures that at least one instance of your application always remains running as the Azure platform undergoes periodic maintenance.
Box 2: the West Europe region and the RG1 resource group

Fault domain - Think about rack, power, network related physically isolated. In this case, we have 2 FD meaning that there are two racks in the data center and each rack is holding 5 VMs (I know this is virtual machine, but assume it). Update domain are used for patching of the virtual machines. When UD is 3 with 10 VMs ---- there will be three UD (3 VMs + 3 VMs + 4VMs= 10 VMs with 3 UD). Now question is asking "AT LEAST" number of VMs, so when last UD (4VMs) is rebooted together, there will be at lest 6 VMs up and running

Planned maintainance implies SW updates ie Update Domains. 10 VMs split across 3 UD implies: UD1---UD2---UD3:----> VM1---VM2---VM3 VM4—VM5---VM6 VM7---VM8---VM9 VM10 Hence in worse, case UD1 with 4 vms will go down, leaving 6 VMs active

Have tried this . the answer is correct. New VM need to be same region as Availability Set and same Resource Group.

Each virtual machine in your availability set is assigned an update domain and a fault domain by the underlying Azure platform. In this scenario, we have configured 3 update domains. If you create three or more VMs across in an Azure region, your VMs are effectively distributed across three update domains. The Azure platform recognizes this distribution across update domains to make sure that VMs in different zones are not updated at the same time. Therefore, two out of three update domains would be available. We have deployed 10 VMs. So, each with update domain will have at least 3 VMs. So there will be at least 6 virtual machines available during any planned maintenance window. To add to same Availability Set, VM is to be in same region and RG Answer is correct

...and one update domain will have 4 VMs, so 10 - 4 = 6

When Update Domain is 3 with 10 VMs ---- (3 VMs + 3 VMs + 4VMs= 10 VMs within 3 UD). When the last UD with 4 VM's is rebooted there will atleast 6 VM's available. Hence Corret Answer is available VM's : 6.The new VM need to be in the same region as Availability Set and in the same Resource Group.
