Microsoft Azure Administrator (AZ104) Practice Exam

Which virtual network is not capable of peering with VNet1 based on the given address spaces?

1. VNet2

2. VNet3

3. VNet4

4. All are capable of peering

The correct answer is: VNet2

To determine which virtual network cannot peer with VNet1, it is essential to understand the concept of virtual network peering and address space management within Azure. When virtual networks are peered in Azure, they must have non-overlapping address spaces. This means that the address range used by VNet1 must be different and not overlap with the address ranges of the other virtual networks. If there is an overlap in address spaces between the networks, peering cannot be established. In this case, the correct choice indicates that VNet2 has an address space that overlaps with the address space of VNet1, which makes it incapable of peering. While VNet3 and VNet4 must have their address spaces examined to assess if they can peer with VNet1, it’s notable that they have configurations that allow them to peer without address conflicts. Recognizing the importance of non-overlapping address spaces in network configurations is key for Azure Administrators managing resources across multiple virtual networks, ensuring connectivity without routing conflicts or communication issues. Therefore, VNet1 cannot establish a peering relationship with VNet2 due to the overlapping addresses it possesses.
