COrrect Answer: Step 1: Remove peering between Vnet1 and VNet2 You can't add address ranges to or delete address ranges from a virtual network's address space once a virtual network is peered with another virtual network. To add or remove address ranges, delete the peering, add or remove the address ranges, then re-create the peering. Step 2: Add the 10.33.0.0/16 address space to VNet1 Step 3: Recreate peering between VNet1 and VNet2 Reference: https://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-manage-peering

Since September 2022 you can update the address space for peered virtual networks without removing the peering. "Updating the address space for peered virtual networks now is now generally available. This feature allows you to update the address space or resize for a peered virtual network without removing the peering."

This question is outdated. You can now add or remove address spaces without having to remove the peering first and re-establishing the peering. You can simply add the address space in VNET1 and perform a resync using Powershell with Sync-AzVirtualNetworkPeering https://learn.microsoft.com/en-us/powershell/module/az.network/sync-azvirtualnetworkpeering?view=azps-10.2.0 FROM: https://learn.microsoft.com/en-us/azure/architecture/networking/prefixes/add-ip-space-peered-vnet ** Note: This article has not yet been updated to reflect Azure networking's support for peering resync. Azure virtual networks support adding and removing address space without the need to remove and restablish peerings; instead each remote peering needs a sync operation performed after the network space has changed. The sync can be performed using the Sync-AzVirtualNetworkPeering PowerShell command or from the Azure Portal.**

Tested in Lab 1.Remove peering between Vnet1 and VNet2 2.Add 10.33.0.0/16 3.Recreate peering between VNet1 and VNet2

Answer is correct.

I see one problem. You can't add subnet 10.33.0.0/16 to vnet 10.1.0.0/16. It is out of range. Error: The subnet address range "10.33.0.0/16" is not contained in this virtual network's address spaces.

Given answer is correct

This question came in the exam today 8/Mar/2022. I passed the exam, 95% questions came from here.

You can't add address ranges to, or delete address ranges from a virtual network's address space once a virtual network is peered with another virtual network. To add or remove address ranges, delete the peering, add or remove the address ranges, then re-create the peering. To add address ranges to, or remove address ranges from virtual networks

On the exam today, 1.feb.2022 Just 761/1000, but OK! :D Thanks to ExamTopics and to you all!

The answer is correct, although there's a new way of the things happening now: "Updating the address space of a virtual network that has peers will cause the peered virtual networks to not be able to connect to this new address space until you perform a sync operation on the peerings. You can sync the peered virtual networks in the peerings tab, but requires you have contributor permissions on the peered virtual networks." https://azure.microsoft.com/en-us/blog/how-to-resize-azure-virtual-networks-that-are-peered-now-in-preview/ So now, it would be: 1. Change the address range 2. ReSync the Peerings

Was on exam today 19.11.2021. Passed with 920. Correct answer: - Remove peering between Vnet1 and VNet2 - Add the 10.33.0.0/16 address space to VNet1 - Recreate peering between VNet1 and VNet2

The only problem with this answer is that peering is set from both sides. While this answer is correct in the selection, It neglects what the impact will be on the peer from VNet2.

Received this question on 4th July exam. There were many other questions from this list(around 16). I could clear the exam. Thanks :-)

Many organizations deploy a virtual networking architecture that follows the Hub and Spoke model. At some point, the hub virtual network might require additional IP address spaces. However, address ranges can't be added or deleted from a virtual network's address space once it's peered with another virtual network. To add or remove address ranges, delete the peering, add or remove the address ranges, then re-create the peering manually. https://docs.microsoft.com/en-us/azure/architecture/networking/prefixes/add-ip-space-peered-vnet

But it doesnt say peering exist already to remove one? Please correct me if im wrong.
