B is the answer. https://learn.microsoft.com/en-us/azure/site-recovery/azure-to-azure-network-mapping The subnet of the target VM is selected based on the name of the subnet of the source VM. - If a subnet with the same name as the source VM subnet is available in the target network, that subnet is set for the target VM. - If a subnet with the same name doesn't exist in the target network, the first subnet in the alphabetical order is set as the target subnet.

I can't understand. Where do you see that the vm1'subnet is any similar to demosubnet1?

There are two rules: 1) If a destination subnet exists with the same name as the source subnet, then that one will be selected as a failover target. 2) If a subnet of the same name does not exist in the destination VNET, then the first subnet according the alphabetical order will be selected. Rule 2 applies for this question, B is therefore the correct answer. See zellck's source: https://learn.microsoft.com/en-us/azure/site-recovery/azure-to-azure-network-mapping#specify-a-subnet

think is A, because vm1 was connected to sunbnet1 172.16.2.0, the destination failover subnet should be testsubnet1 because it has 172.16,2,0

Selected Answer: A
In the given scenario, you have configured Azure Site Recovery to replicate VM1 from VNET1 (US East) to VNET2 (West US). During the test failover, you specified VNET2 as the target virtual network. Understanding the likely target subnet: Since VM1 is originally connected to Subnet2 in VNET1 with an address range of 172.16.2.0/24, it will typically map to a similar subnet range in the target VNET. In VNET2, the subnet that matches this IP range is TestSubnet1, which has the same address range 172.16.2.0/24. Conclusion: The test version of VM1 will be connected to TestSubnet1 during the test failover. Thus, the correct answer is: A. TestSubnet1.

brainless microsoft, prefer using same subnet range for the sake of routing, security groups, etc..

A is the correct answer. During a failover, Azure Site Recovery tries to find a corresponding subnet in the target virtual network (VNET2) that matches the original subnet's address range and/or name. In this case, the testsubnet 1 has the matching IP address range.

If a subnet with the same name doesn't exist in the target network, the first subnet in the alphabetical order is set as the target subnet.

B) Apparently if the target subnet doesn't have the same name, then it picks it via alphabetical order. https://learn.microsoft.com/en-us/azure/site-recovery/azure-to-azure-network-mapping#specify-a-subnet

logically when you failover same subnet CIDR means less work to do.

but obviously Azure doesn't follow logic by default . Answer is B . "Specify a subnet The subnet of the target VM is selected based on the name of the subnet of the source VM. - If a subnet with the same name as the source VM subnet is available in the target network, that subnet is set for the target VM. - If a subnet with the same name doesn't exist in the target network, the first subnet in the alphabetical order is set as the target subnet. You can modify the target subnet in the Network settings for the VM. 2. IP address assignment during failover - Same address space: IP address of the source VM NIC is set as the target VM NIC IP @.If the address isn't available, the next available IP is set as the target. - Different address space: The next available IP address in the target subnet is set as the target VM NIC address. <<-- this means it can be a different IP CIDR.
