Difficulty: EasyAzure Virtual Networks, ExpressRoute, and VPN Gateway

A company is setting up a hybrid network to link their local office to resources in Azure. Is the statement 'Azure ExpressRoute sends network traffic over the public internet' true or false?

Answer: Answer

Answer

The statement is false because Azure ExpressRoute utilizes a private, dedicated connection that does not traverse the public internet.
The statement is false. Azure ExpressRoute provides a dedicated, private connection to Microsoft services that bypasses the public internet entirely. This provides higher reliability, faster speeds, and lower latencies than typical connections over the internet.

Step-by-Step Solution

1
Identify the primary transmission path used by Azure ExpressRoute.
Azure ExpressRoute connects on-premises networks to Microsoft cloud services over a private connection facilitated by a connectivity provider.
To determine whether the traffic traverses the public internet, we must look at how the physical and logical connection is established.
2
Compare the identified path with the public internet.
The connection is private and explicitly bypasses the public internet, unlike a VPN which encrypts traffic over the public internet.
This confirms that the statement 'Azure ExpressRoute sends network traffic over the public internet' is incorrect.

Key Concept

Azure ExpressRoute provides a private, dedicated connection to Azure that does not traverse the public internet.
