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.
VNet-Hub and VNet-Spoke1 are in the same region and subscription. Resources in the two VNets must communicate over the Microsoft backbone without using a VPN gateway. What should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
VNet peering
VNet peering enables direct connectivity between two virtual networks in the same region and subscription over the Microsoft backbone, without requiring a VPNgateway or public internet. This is the correct solution because it provides low-latency, private communication using the Azure infrastructure, and it supports resources in both VNets to communicate as if they were on the same network.
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
Why this is correct
Peering is the standard way to connect VNets privately over the Azure backbone.

✗
A site-to-site VPN gateway in each VNet
Why it's wrong here
That adds unnecessary gateway infrastructure for VNets in Azure.
✗
A private endpoint
Why it's wrong here
Private endpoints connect to individual Azure services, not whole-VNet communication.
✗
A service endpoint
Why it's wrong here
Service endpoints extend a VNet identity to PaaS services but do not connect two VNets.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse VNet peering with VPN gateways or service endpoints, mistakenly thinking a VPN gateway is required for cross-VNet communication or that service endpoints can connect VNets, when in fact VNet peering is the native, gateway-free solution for direct VNet-to-VNet connectivity within the same region.
Detailed technical explanation
How to think about this question
VNet peering uses the Azure backbone network to route traffic between VNets via the Azure infrastructure, leveraging RFC 1918 private IP addresses and supporting transitive routing only if explicitly configured with hub-and-spoke topologies. Under the hood, peering creates a routing entry in each VNet's route table for the peered VNet's address space, and traffic flows through Azure's high-speed fabric without any gateway or encryption overhead. In a real-world scenario, if you need to connect multiple spoke VNets to a hub VNet for shared services (like a firewall or DNS), you would use VNet peering and optionally configure the hub as a gateway transit point, but note that non-transitive peering means spoke-to-spoke traffic must go through the hub unless additional peering is established.

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.
