Developing Solutions for Microsoft Azure (AZ-204) Practice Exam

Which of the following is not a benefit of using ExpressRoute?

1. Consistent network throughput

2. Redundant connectivity

3. Access to Microsoft cloud services

4. Encrypted network communication

The correct answer is: Encrypted network communication

ExpressRoute is a service that provides a private connection between an organization's on-premises infrastructure and Microsoft Azure's data centers. One of the key benefits is that it facilitates a secure and reliable connection, optimizing network performance and user experience. Among the mentioned benefits, consistent network throughput is crucial for applications requiring high bandwidth and low latency. Users can experience predictable performance levels without the fluctuations typical of public internet connections. Redundant connectivity ensures that there are multiple links to maintain network reliability, minimizing downtime and enhancing resilience against connectivity failures. Access to Microsoft cloud services is a fundamental advantage of ExpressRoute; it allows organizations to utilize Azure services without exposing their data traffic to the public internet, benefiting from enhanced security and performance. While encrypted network communication is important for handling sensitive data across any network, ExpressRoute itself does not provide encryption as a built-in feature. Instead, encryption would need to be implemented at higher layers of the network stack, such as through VPN tunnels or by using application-level encryption. Therefore, it is the aspect that does not directly represent a benefit of ExpressRoute itself.
