Microsoft Azure Architect Design (AZ-301) Practice Exam

The correct choice is Azure ExpressRoute because it provides a private and dedicated connection from on-premises environments to Azure services. This connection bypasses the public internet, which enhances security, reliability, and performance. ExpressRoute allows for larger bandwidth and lower latency compared to traditional internet connections, making it suitable for enterprises needing a high degree of connectivity and data transfer capabilities.

VPN Gateway, while it allows secure encrypted communication over the public internet, does not offer the same level of performance or reliability as ExpressRoute. Azure Bastion is designed to provide secure remote access to virtual machines without exposing them directly to the internet but does not create a direct network connection to Azure resources. Azure VNet Peering enables virtual networks to communicate with each other but does not facilitate secure connectivity from on-premises to Azure resources like ExpressRoute does.
