Microsoft Azure Architect Technologies (AZ-300) Practice Exam

VNet peering in Azure serves the primary purpose of enabling communication between Azure virtual networks. When two virtual networks are peered, they allow resources in those networks to communicate with each other as if they are part of the same network. This communication occurs through private IP addresses and doesn’t require any special gateways or routing configurations, which simplifies connectivity and enhances performance. VNet peering supports scenarios where you need to connect multiple virtual networks to share resources or create a multi-tier application architecture that relies on different virtual networks but requires seamless connectivity between them. This is especially important in scenarios where applications spread across different virtual networks need to exchange data or perform interactions without additional latency or security overhead. While there are other aspects of Azure networking that address on-premises security, user authentication connections, or creating virtual networks in specific regions, these do not directly pertain to the core function of VNet peering. The focused capability of VNet peering is on establishing a direct network link between Azure virtual networks, facilitating efficient and secure communication.
