Which service is commonly used to create a dedicated connection from an on-premises network to Azure?

  1. Site-to-Site VPN

  2. Azure Front Door

  3. ExpressRoute

  4. Cloud Services

The correct answer is: ExpressRoute

The preferred service for establishing a dedicated connection from an on-premises network to Azure is ExpressRoute. This service provides a private connection that does not traverse the public internet, offering benefits such as increased security, reliability, and faster speeds. With ExpressRoute, organizations can connect their local network directly to Azure data centers, which helps in scenarios requiring high throughput and low latency. While a Site-to-Site VPN is another option for connecting on-premises networks to Azure, it relies on public internet infrastructure. This can introduce variabilities in speed and security compared to ExpressRoute, making it less suited for businesses that need a consistent and high-performance connection. Azure Front Door and Cloud Services serve different purposes within the Azure ecosystem. Azure Front Door is designed for global load balancing and acceleration of web applications, while Cloud Services typically refer to a collection of services for hosting applications in the cloud, rather than facilitating direct network connections.
