Question
You have an Azure subscription that contains four Azure Virtual Networks named VNet1, VNet2, VNet3, and VNet4. The subscription contains the following Azure Virtual Machines:
VM1: Attached to VNet1
VM2: Attached to VNet2
VM3: Attached to VNet3
VM4: Attached to VNet4
You configure the following virtual network peering:
VNet1 is peered with VNet2.
VNet3 is peered with VNet4.
VNet4 is peered with VNet2.
With which virtual machines can VM2 communicate?
A. VM1 and VM3 only
B. VM1 and VM4 only
C. VM1, VM3, and VM4
D. VM3 only
Answer
B. VM1 and VM4 only
Explanation
Azure routing is not fully transitive since virtual network service chaining routes are only advertised to their direct peers. So even though VNet3 is connected to VNet2 via VNet4, VM2 can only communicate with VM1 and VM4 since they are directly connected.
