AZ-104 Implement and Manage Virtual Networking Practice Question

This AZ-104 practice question tests your understanding of implement and manage virtual networking. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.

Two application VNets are deployed in different Azure regions. Each VNet uses a unique, non-overlapping address space. The application teams want private IP connectivity over the Microsoft backbone with the lowest possible latency between the regions. Which design should the administrator choose?

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

Global VNet peering.

Global VNet peering provides direct, private IP connectivity between two VNets in different Azure regions over the Microsoft backbone, ensuring the lowest possible latency by bypassing the public internet and any intermediate gateways. It uses the Azure infrastructure to route traffic efficiently between the peered VNets, meeting the requirement for private, low-latency communication.

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.

  • Global VNet peering.

    Why this is correct

    Global VNet peering is the correct choice for private connectivity between VNets in different Azure regions. It keeps traffic on the Microsoft backbone, uses private IP addressing, and avoids the added latency and overhead of an external VPN tunnel. Because the VNets already have non-overlapping address spaces, they meet the peering prerequisites. This design is commonly used when multiple regional workloads need fast, private communication without introducing a gateway-based path.

    Related concept

    Read the scenario before looking for a memorised answer.

  • A site-to-site VPN between the two VNets.

    Why it's wrong here

    A VPN would add unnecessary complexity and latency when Azure-native peering can provide direct private connectivity.

    When this WOULD be correct

    A site-to-site VPN would be correct if the requirement is to connect on-premises networks to Azure VNets, or to connect VNets across regions when VNet peering is not supported (e.g., different Azure clouds or classic VNets).

  • Azure Traffic Manager with two public endpoints.

    Why it's wrong here

    Traffic Manager directs clients at the DNS layer and does not create private IP connectivity between VNets.

    When this WOULD be correct

    This option would be correct in a scenario where the requirement is to distribute incoming user traffic across multiple public endpoints (e.g., web applications) in different regions for high availability and low latency, without needing private IP connectivity between the VNets.

  • A service endpoint for each application subnet.

    Why it's wrong here

    Service endpoints are for secure access to supported PaaS services, not VNet-to-VNet application traffic.

    When this WOULD be correct

    A question requiring secure, private access from a VNet to an Azure SQL Database or Storage Account, minimizing exposure to the public internet, would make service endpoints the correct answer. For example: 'You need to ensure that traffic from a VNet to Azure Storage never traverses the public internet.'

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.

Global VNet peering.Correct answer

Why this is correct

Global VNet peering is the correct choice for private connectivity between VNets in different Azure regions. It keeps traffic on the Microsoft backbone, uses private IP addressing, and avoids the added latency and overhead of an external VPN tunnel. Because the VNets already have non-overlapping address spaces, they meet the peering prerequisites. This design is commonly used when multiple regional workloads need fast, private communication without introducing a gateway-based path.

A site-to-site VPN between the two VNets.Wrong answer — click to see why

Why this is wrong here

Site-to-site VPN uses the public internet or ExpressRoute with VPN gateway, which introduces higher latency and does not leverage the Microsoft backbone for the lowest latency path between VNets.

★ When this WOULD be the correct answer

A site-to-site VPN would be correct if the requirement is to connect on-premises networks to Azure VNets, or to connect VNets across regions when VNet peering is not supported (e.g., different Azure clouds or classic VNets).

Why candidates choose this

Candidates may think VPN provides private connectivity and is suitable for inter-region connections, but they overlook that VNet peering offers lower latency over the Microsoft backbone without a VPN gateway.

Azure Traffic Manager with two public endpoints.Wrong answer — click to see why

Why this is wrong here

Azure Traffic Manager operates at the DNS level for traffic routing based on performance or geographic location, but it does not provide private IP connectivity between VNets; it requires public endpoints and does not enable direct VNet-to-VNet communication over the Microsoft backbone.

★ When this WOULD be the correct answer

This option would be correct in a scenario where the requirement is to distribute incoming user traffic across multiple public endpoints (e.g., web applications) in different regions for high availability and low latency, without needing private IP connectivity between the VNets.

Why candidates choose this

Candidates may confuse Traffic Manager's latency-based routing with providing low-latency private connectivity, or they might think that Traffic Manager can route traffic between VNets because it can direct traffic to endpoints in different regions.

A service endpoint for each application subnet.Wrong answer — click to see why

Why this is wrong here

Service endpoints provide secure connectivity from a VNet to Azure PaaS services (like Storage or SQL) over the Microsoft backbone, not private IP connectivity between two VNets. They do not enable VNet-to-VNet routing or inter-region private connectivity.

★ When this WOULD be the correct answer

A question requiring secure, private access from a VNet to an Azure SQL Database or Storage Account, minimizing exposure to the public internet, would make service endpoints the correct answer. For example: 'You need to ensure that traffic from a VNet to Azure Storage never traverses the public internet.'

Why candidates choose this

Candidates may confuse service endpoints with VNet peering or assume that 'service endpoint' implies general private connectivity between VNets, not realizing it is limited to Azure PaaS services.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse site-to-site VPN (Option B) as a private connectivity method, overlooking that its encryption overhead and gateway processing introduce higher latency compared to the direct, unencrypted path of Global VNet peering.

Detailed technical explanation

How to think about this question

Global VNet peering leverages the Azure backbone network to route traffic between VNets in different regions with minimal hops, using the same high-speed infrastructure that Azure uses for internal traffic. Unlike VPNs, peering does not require encryption, reducing overhead and latency, and it supports transitive routing only if explicitly configured via network virtual appliances or hub VNets. In real-world scenarios, this design is ideal for multi-region application deployments requiring synchronous replication or real-time data exchange.

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.
