- A
VNet peering between the two virtual networks.
VNet peering provides private, low-latency communication between virtual networks when their address spaces do not overlap.
- B
A site-to-site VPN gateway connection.
Why wrong: VPN gateways are used for encrypted network connections, but they are not required for direct VNet-to-VNet communication.
- C
A service endpoint on both subnets.
Why wrong: Service endpoints extend subnet identity to a service, but they do not connect two VNets together.
- D
A route table with default routes to each VNet.
Why wrong: Route tables can influence next hops, but they do not create the private connectivity needed between VNets.

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.
An administrator needs two non-overlapping VNets in the same region to communicate directly over private IP addresses without deploying a gateway. What should be configured?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
VNet peering between the two virtual networks.
VNet peering enables direct connectivity between two Azure virtual networks using private IP addresses across the Microsoft backbone, without requiring a gateway or public internet. It supports non-overlapping address spaces in the same region and provides low-latency, high-bandwidth communication. This matches the requirement exactly.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
VNet peering between the two virtual networks.
Why this is correct
VNet peering provides private, low-latency communication between virtual networks when their address spaces do not overlap.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
A site-to-site VPN gateway connection.
Why it's wrong here
VPN gateways are used for encrypted network connections, but they are not required for direct VNet-to-VNet communication.
- ✗
A service endpoint on both subnets.
Why it's wrong here
Service endpoints extend subnet identity to a service, but they do not connect two VNets together.
When this WOULD be correct
A question asks: 'How to ensure traffic from a subnet to an Azure Storage account stays on the Microsoft backbone and does not traverse the internet?' — here, configuring a service endpoint on the subnet would be correct.
- ✗
A route table with default routes to each VNet.
Why it's wrong here
Route tables can influence next hops, but they do not create the private connectivity needed between VNets.
When this WOULD be correct
A route table with default routes to each VNet would be correct in a scenario where you need to force-tunnel traffic from both VNets through a network virtual appliance (NVA) or on-premises firewall for inspection, using user-defined routes (UDRs).
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-104 exam frequently reuses these exact scenarios with slightly different constraints.
✓VNet peering between the two virtual networks.Correct answer▾
Why this is correct
VNet peering provides private, low-latency communication between virtual networks when their address spaces do not overlap.
✗A site-to-site VPN gateway connection.Wrong answer — click to see why▾
Why this is wrong here
A site-to-site VPN gateway connection requires a gateway and routes traffic over the internet or ExpressRoute, not directly over private IPs, and incurs additional cost and complexity.
★ When this WOULD be the correct answer
When connecting on-premises networks to Azure, or connecting VNets across regions or subscriptions where VNet peering is not supported or desired, a site-to-site VPN gateway connection would be correct.
Why candidates choose this
Candidates may confuse site-to-site VPN with VNet peering, thinking both provide connectivity, but overlook the 'without deploying a gateway' and 'private IP' constraints in the question.
✗A service endpoint on both subnets.Wrong answer — click to see why▾
Why this is wrong here
Service endpoints secure Azure service access from a VNet but do not enable direct private IP communication between two VNets; they only provide a direct path to PaaS services, not VNet-to-VNet connectivity.
★ When this WOULD be the correct answer
A question asks: 'How to ensure traffic from a subnet to an Azure Storage account stays on the Microsoft backbone and does not traverse the internet?' — here, configuring a service endpoint on the subnet would be correct.
Why candidates choose this
Candidates may confuse service endpoints with VNet peering, thinking both provide direct connectivity, but service endpoints are for accessing Azure services, not for VNet-to-VNet communication.
✗A route table with default routes to each VNet.Wrong answer — click to see why▾
Why this is wrong here
Route tables with default routes to each VNet do not enable direct private IP communication between VNets; they only control traffic within a VNet or to forced-tunneling destinations. VNet peering is required for direct connectivity.
★ When this WOULD be the correct answer
A route table with default routes to each VNet would be correct in a scenario where you need to force-tunnel traffic from both VNets through a network virtual appliance (NVA) or on-premises firewall for inspection, using user-defined routes (UDRs).
Why candidates choose this
Candidates may think that adding routes to the other VNet's address space in a route table is sufficient to enable cross-VNet communication, misunderstanding that route tables alone do not establish connectivity without a peering or gateway.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse VNet peering with VPN gateways or service endpoints, assuming a gateway is always required for cross-VNet communication or that service endpoints can connect VNets, when in fact peering is the direct, gateway-free solution for private IP connectivity.
Detailed technical explanation
How to think about this question
VNet peering uses the Azure backbone to route traffic between VNets with no intermediate hops, leveraging the underlying SDN fabric. Traffic stays within the Azure network and is subject to regional peering bandwidth limits (up to 10 Gbps per peering link). A common real-world scenario is connecting a hub VNet (with shared services) to spoke VNets for microservices communication, avoiding gateway bottlenecks.
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.
