AZ-700 Question 48
Single answerYour company operates multiple virtual networks across three different subscriptions and regions. You have created an Azure Virtual Network Manager instance, defined a single network group that contains all of your virtual networks, and configured a connectivity configuration that should allow inter-network traffic. However, you still cannot pass any traffic between these virtual networks. Which additional action must you take to enable connectivity among the virtual networks in the group?
- A
Add each virtual network to separate network groups, one for each region.
- B
Create a security admin configuration for each subscription in Azure Virtual Network Manager.
- C
Apply the connectivity configuration to the network group in Azure Virtual Network Manager.
- D
Manually add a default route to each virtual network� route table.
Show answer and explanation
Correct answer: C
Explanation
In Azure Virtual Network Manager, defining a connectivity configuration alone does not automatically enable inter-network traffic. You must apply the connectivity configuration to the relevant network group(s) so that Azure can provision and enforce the required routing. This final application step is essential to ensure that the desired connectivity takes effect. Refer to Microsoft documentation (https://learn.microsoft.com/azure/virtual-network-manager/) for detailed steps on creating and applying connectivity configurations.
- A. Incorrect.
Option 1: Incorrect. While you can create multiple network groups for more granular management, Azure Virtual Network Manager does not require separate network groups for each region. A single network group that includes all relevant virtual networks across regions can be used.
- B. Incorrect.
Option 2: Incorrect. A security admin configuration enforces security rules (such as network security group-like rules) within Azure Virtual Network Manager, not basic connectivity. Connectivity configurations and security admin configurations serve different purposes.
- C. Correct.
Option 3: Correct. After creating a connectivity configuration, you must explicitly apply that configuration to your network group (or groups) to enable inter-network connectivity. If you do not apply the configuration, traffic will not flow as intended.
- D. Incorrect.
Option 4: Incorrect. Manually adding default routes to each network's route table is not necessary when using Azure Virtual Network Manager for connectivity. Once the connectivity configuration is applied, routes are handled at the Azure Virtual Network Manager level.
