Microsoft Azure Architect Design (AZ-301) Practice Exam

What virtual network peering topology minimizes administrative effort in an Azure subscription with mixed virtual network types?

1. Frame- and X-Shaped (6 connections)

2. Vnet1 to others (3 connections)

3. Vnet2 to others (3 connections)

4. Frame-Shaped and Vnet2 to Vnet3 (Z-Shaped) (5 connections)

The correct answer is: Vnet1 to others (3 connections)

The option that minimizes administrative effort in a mixed Azure virtual network topology is the one with the least number of connections required to achieve the desired connectivity between the virtual networks. In this scenario, peering involves connecting multiple virtual networks to allow resources within them to communicate. By selecting the approach that allows one virtual network to connect to others directly with a minimal number of connections, you effectively reduce complexity and administrative overhead. This is particularly important in environments where you have different types of virtual networks, as managing multiple connections can become cumbersome. By focusing on connecting one central virtual network (in this case, Vnet1) to the others with only three connections, this option streamlines the management of the network's connectivity. Fewer connections mean less configuration and less monitoring, leading to lower administrative effort overall. Topologies with more connections, such as a frame shape or Z-shaped topology, involve increased complexity and require maintaining additional peering relationships, which can lead to increased management effort and potential issues. Therefore, the choice that allows for a straightforward and low-maintenance approach to connecting multiple virtual networks while effectively managing them is the one that connects Vnet1 to the others with three connections.
