Suggested Answer:
Box 1: add an address space -
Your IaaS virtual machines (VMs) and PaaS role instances in a virtual network automatically receive a private IP address from a range that you specify, based on the address space of the subnet they are connected to. We need to add the 192.168.1.0/24 address space.

Box 2: add a network interface -
The 10.2.1.0/24 network exists. We need to add a network interface.

No you can't add 10.2.1.0/24 because it overlaps with 10.2.0.0/16. Check on Lab

No, I am wrong I am adding 10.2.1.0/24 in address space however it already exists. I need to add a subnet. I get confuse between address spaces and subnets.

Address spaces there can be more than one per vNET; Subnets are subsets of the address spaces, there can be more than a subnet for each address space.

I tested this in the lab. Box 1: Add an address space - explanation: One can add additional address space (192.168.0.0/16) to the VNet1, without having to delete existing (10.2.0.0/16). Box 2: Add subnet - explanation: Defined 'default' subnet from image example (10.2.0.0/24) contains 254 IP addresses, with last IP being 10.2.0.254. In order to assign 10.2.1.0/24 IP address to VM we need to create add new subnet.

Also wrong, the subnet range being created is 10.2.0.0 - 10.2.0.255 . So if you want to add an IP address from 10.2.1.0/24 you need to add a new subnet. Why are so many of these wrong?

There is no dissent. Throw says the initial _subnet_ is 10.2.0.0 - 10.2.0.255. You say the initial vnet _address space_ is 10.2.0.0 - 10.2.255.255. Both is true. However, in the first question you have to _first_ add an address space. (and then a subnet) In the second question you only have to add a subnet as 10.2.1.0/24 is within the vnet's address range 10.2.0.0/16

Some of them are obviously wrong and not getting corrected. It looks like this service is intentionally kind of paired with MS behind the scenes, to force us learn on dumps instead of us trying to learn dumps answers by hard.

There are other similar dumps on the internet which have incorrect answers. My best guess is the base for these questions come from what the Exam Topics team was able to find online. From that base their moderators can update the questions and community can vote on what looks like the best option. Personally, I like to be able to read everyone's comments and read through the additional information and viewpoints. Some of the questions are just bad in general and I like knowing I'm not the only one who thinks they're bad.

The VNET's address space is set to 10.2... How are you going to add a 192. subnet to a 10.2 VNET? You have to tear down the existing VNET by deleting the subnet and redoing the address space to a 192... Then add subnet for the second question.

to add /modify a address space, we need to delete the existing subnet (otherwise it will not allow to modify address space)

OpenAI "Before a virtual machine on VNet1 can receive an IP address from 192.168.1.0/24, you must first add a subnet. This is because the current address space of VNet1 is 10.2.0.0/16, which does not include the 192.168.1.0/24 address range. Before a virtual machine on VNet1 can receive an IP address from 10.2.1.0/24, no further action is required as this address range falls within the existing address space of VNet1 (10.2.0.0/16) and a subnet with the required address prefix can be created within this address space."

First Answer: delete subnet Explanation: Current IP Address Range of VNET1 is 10.2.0.0/16 with subnet 10.2.0.0/24. We want VM1 to get IP from 192.168.1.0/24. In order to do that we need to change the IP address range of VNET1. We can not add a new IP address range on existing one. I see so many comments add an address space. 1.Delete Subnet 10.2.0.0/24 2.Change the IP range Address Range in Address Space from 10.2.0.0/16 to 192.168.0.0/16 3.Add Subnet with 192.168.1.0/24 Second Answer: Add Subnet The new Subnet with address10.2.1.0/24 is in the range of IP Address range of VNET1 10.2.0.0/16(10.2.0.0 to 10.2.255.255)

The only subnet in the vnet is of address range 10.2.0.0/24 So address range usable for any VM is 10.2.0.4 to 10.2.0.254 For assigning the IP from the space 10.2.1.0/24 you need a subnet with that IP range.
