Quick Answer
The answer is to ensure the virtual networks are in the same Azure region, verify non-overlapping address spaces, and configure virtual network peering. This is correct because VNet peering in the same region requires that the IP address ranges do not overlap—such as 10.0.0.0/16 and 10.1.0.0/16—to avoid routing conflicts, and peering itself establishes direct, encrypted connectivity over the Microsoft backbone network without traversing the public internet. On the AZ-104 exam, this scenario tests your understanding of regional peering prerequisites versus global peering, with a common trap being to assume that overlapping address spaces can be resolved or that a VPN gateway is needed for same-region traffic. Remember the key prerequisites as the “three Ns”: Non-overlapping addresses, Network peering enabled, and the same regioN.
AZ-104 Implement and Manage Virtual Networking Practice Question
This AZ-104 practice question tests your understanding of implement and manage virtual networking. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Your company has two Azure virtual networks in the same region: VNetA (10.0.0.0/16) and VNetB (10.1.0.0/16). You need to enable communication between resources in VNetA and VNetB while ensuring that traffic is encrypted and passes over the Microsoft backbone network. Which three of the following must be configured? (Choose three.)

Correct answer & explanation
✓
Configure virtual network peering between VNetA and VNetB.
Virtual network peering is required to enable direct connectivity between VNetA and VNetB, allowing resources in both networks to communicate over the Microsoft backbone network. Verifying that the address spaces do not overlap (10.0.0.0/16 and 10.1.0.0/16) is a prerequisite for successful peering, as overlapping ranges would cause routing conflicts. Ensuring the virtual networks are in the same Azure region is necessary because standard virtual network peering only works within the same region; global peering would be required for cross-region connectivity, but the question specifies the same region.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse virtual network peering with site-to-site VPN or gateway transit, mistakenly thinking encryption or gateway configuration is required for intra-region peering, when in fact peering itself uses the Microsoft backbone and is inherently secure without additional VPN setup.
Detailed technical explanation
How to think about this question
Virtual network peering uses the Microsoft backbone infrastructure to route traffic between VNets with low latency and high bandwidth, and traffic remains private without traversing the public internet. Peering is non-transitive by default, meaning if VNetA is peered to VNetB and VNetB to VNetC, VNetA cannot communicate with VNetC unless explicitly peered. In this scenario, the address spaces are non-overlapping (10.0.0.0/16 and 10.1.0.0/16), which is critical because overlapping ranges would cause routing ambiguity and prevent successful peering.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
