Which Virtual Networks Can Peer with VNet1 Across Tenants

AZ-104 By islever Editorial Last updated

Configure and manage virtual networks in Azure

Short answer

E VNet1 can be peered with VNet2, VNet3, VNet4, and VNet5 because Azure supports global and cross-tenant virtual network peering.

Question

You have two Azure subscriptions named Sub1 and Sub2 that are linked to separate Microsoft Entra tenants. You have the virtual networks shown in the following table. Which virtual networks can you peer with VNet1? - Exhibit: Which Virtual Networks Can Peer with VNet1 Across Tenants
  1. VNet2 only
  2. VNet2 and VNet3 only
  3. VNet2 and VNet4 only
  4. VNet2, VNet3, and VNet4 only
  5. VNet2, VNet3, VNet4, and VNet5 Correct Answer

Key Takeaways

VNet peering supports cross-region and cross-tenant connections, making all non-overlapping VNets eligible regardless of subscription or tenant boundaries.

Azure virtual network peering supports connecting VNets across different regions and different Microsoft Entra tenants. This page confirms that VNet1 can be peered with VNet2, VNet3, VNet4, and VNet5.

Common mistake: Choosing B (VNet2 and VNet3 only) by incorrectly assuming that VNets in different subscriptions or separate Entra tenants cannot be peered.

Expert Analysis

Why the Answer Is Correct

Azure virtual network peering allows connectivity between virtual networks across different regions (global peering) and across different Microsoft Entra tenants. As long as the address spaces do not overlap, VNet1 can peer with any of the listed virtual networks, making VNet2, VNet3, VNet4, and VNet5 valid targets. This cross-tenant capability requires appropriate permissions but is fully supported by the platform.

Why the Other Options Are Wrong

Options A, B, C, and D all incorrectly exclude one or more valid virtual networks. The exclusion of VNet4 and VNet5 is typically based on the false assumption that cross-tenant peering is impossible. Excluding VNet3 assumes global peering is not supported, which is also incorrect.

Community Comment Notes

Many learners correctly pointed out that global and cross-tenant peering are supported, as Henrytml noted "peer virtual networks across different regions and tenants in Azure". However, some users mistakenly argued that isolated tenants prevent peering, failing to recognize that cross-tenant peering is a supported Azure feature when permissions are correctly configured.

Exam Strategy

For VNet peering questions, remember that peering is supported across regions (global peering) and across Microsoft Entra tenants. Do not assume tenant boundaries block peering; only overlapping IP address spaces prevent it.

    Given answer E is right , Global virtual network peering enables you to peer virtual networks in different regions.
  3. 082c09e 👍 3
    E. VNet2, VNet3, VNet4, and VNet5

    As per the link below the answer is E - https://learn.microsoft.com/en-us/azure/virtual-network/virtual-network-peering-overview

    Peering Requirements: Non-Overlapping Address Spaces: The address spaces of the peered virtual networks must not overlap. (We need to assume they don't overlap as the table doesn't specify address spaces.) Same Azure Region or Global Peering: Peering can be done within the same region or across regions (global peering). Subscription Permissions: The user establishing the peering must have the necessary permissions on both virtual networks. Same Microsoft Entra Tenant (or Global Peering Considerations): Peering across tenants requires specific configurations and permissions.

    What are you lot on about? The question states nothing that the tenants are linked in anyway aside from the fact it states its "linked to different tenants"; effectivly they are completly isolated so how can VNET1 peer with 4 and 5? Even chatgpt says the same thing! Its 2 and 3 guys.

    All them. Of course. Peer across tenants is possible. And across regions.
