Question

Difficulty: MediumAzure Virtual Networks, ExpressRoute, and VPN Gateway

Determine if the following statement is true or false: An Azure ExpressRoute connection routes network traffic between an on-premises network and Azure resources over the public internet using built-in IPsec encryption.

Answer: Answer

Answer

False
The statement is false. Azure ExpressRoute provides a private connection to Microsoft services via dedicated circuits. Therefore, traffic does not traverse the public internet, and it is not encrypted by default.

Step-by-Step Solution

1
Analyze the transmission medium described in the statement.
ExpressRoute utilizes private, dedicated WAN links provided by a partner connectivity provider.
This establishes that ExpressRoute traffic does not travel over the public internet.
2
Analyze the default encryption state of ExpressRoute.
ExpressRoute does not encrypt traffic by default.
While customers can configure encryption over ExpressRoute, it is not built-in or enabled by default.

Key Concept

ExpressRoute provides a private, dedicated, and unencrypted-by-default connection that bypasses the public internet.
