Microsoft Azure Architect Design (AZ-304) Practice Test

Which of the following would be an important consideration when choosing a load balancer for a web application in Azure?

1. Geographical redundancy.

2. Latency in data transfer.

3. Application compatibility.

4. All of the above.

The correct answer is: All of the above.

When choosing a load balancer for a web application in Azure, multiple factors come into play, making several considerations integral to ensuring optimal performance and resilience of the application. Geographical redundancy plays a critical role in load balancing as it allows the application to remain functional in the event of an outage in one region. By having resources balanced across different geographical locations, you can ensure high availability and disaster recovery, which are essential for applications that require constant uptime and reliability. Latency in data transfer affects user experience and application performance. Selecting a load balancer that minimizes latency by routing traffic to the nearest backend resource is crucial. This consideration ensures that users experience quicker response times and that the application can handle similar loads efficiently across varied locations. Application compatibility is another key consideration. It's important to evaluate whether the chosen load balancer can effectively work with the underlying architecture, protocols, and features of the application, enabling smooth integration and functioning without causing disruptions or conflicts in service. Given that all of these factors play a significant role in the effective functioning of a load-balancing solution for web applications, they must be evaluated together to select a load balancer that aligns well with the specific needs of the application and the overall architecture in Azure.
