Actual exam question from Microsoft's AZ-303
Question #: 9
Topic #: 1
[All AZ-303 Questions]

You have a virtual network named VNet1 as shown in the exhibit. (Click the Exhibit tab.)

No devices are connected to VNet1.
You plan to peer VNet1 to another virtual network named VNet2. VNet2 has an address space of 10.2.0.0/16.
You need to create the peering.
What should you do first?

  • A. Configure a service endpoint on VNet2.
  • B. Add a gateway subnet to VNet1.
  • C. Create a subnet on VNEt1 and VNet2.
  • D. Modify the address space of VNet1.

Suggested Answer: D 🗳️
The virtual networks you peer must have non-overlapping IP address spaces. The exhibit indicates that VNet1 has an address space of 10.2.0.0/16, which is the same as VNet2, and thus overlaps. We need to change the address space for VNet1.

Answer is D. Just like AWS VPC peering, peering VNets/VPC can not be done if the CIDR ranges overlaps each other. Also remember peering is not transitive meaning peering VNet A to VNet B, VNet B to VNet C, Vnet A can not communicate with Vnet C
