Difficulty: HardAzure Virtual Networks, ExpressRoute, and VPN Gateway

A company is planning a hybrid network architecture to connect their on-premises datacenter to Azure services. Due to strict compliance requirements, all data transferred must be encrypted in transit. The network administrator proposes using a standard Azure ExpressRoute circuit to meet both the high-bandwidth demand and the encryption requirement. True or false: The proposed solution meets the encryption requirement by default.

Answer: Answer

Answer

False
The proposed solution does not meet the encryption requirement by default. Although Azure ExpressRoute provides a private, high-speed, and low-latency connection that bypasses the public internet, it does not encrypt data in transit by default. To achieve encryption over ExpressRoute, additional configurations like a site-to-site VPN over the circuit or MACsec (for ExpressRoute Direct) must be implemented.

Step-by-Step Solution

1
Analyze the requirements in the scenario.
The requirements are high-bandwidth connectivity and guaranteed encryption in transit for data moving between on-premises and Azure.
Understanding the customer's constraints is the first step in determining the correctness of the proposal.
2
Evaluate the capabilities of a standard Azure ExpressRoute circuit.
ExpressRoute provides high bandwidth, low latency, and a private connection that bypasses the public internet, but it does not encrypt traffic by default.
We must verify if the proposed technology natively satisfies the encryption requirement without additional setup.
3
Determine if the proposed solution meets the encryption requirement by default.
Since standard ExpressRoute does not encrypt traffic in transit by default, the proposed solution does not meet the compliance requirement on its own.
This leads to the final determination that the statement is false.

Key Concept

Azure ExpressRoute provides private, high-bandwidth connectivity to Azure but does not encrypt traffic by default.
