Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

Which type of traffic does Azure Load Balancer support?

1. Only internet-facing traffic

2. Only internal traffic

3. Both external and internal traffic

4. Traffic from third-party services

The correct answer is: Both external and internal traffic

Choosing to support both external and internal traffic showcases the versatility of Azure Load Balancer. This service is designed to distribute incoming network traffic across multiple servers efficiently, ensuring optimal performance and reliability for applications. By facilitating incoming traffic from the internet (external) as well as managing traffic within a private network (internal), Azure Load Balancer allows organizations to build scalable and resilient architectures. The ability to balance load across virtual machines or instantiated services, regardless of whether the traffic is sourced externally or internally, makes it a vital component in maintaining availability and improving response times for applications running in Azure. Additionally, this dual functionality enables effective handling of various scenarios, such as distributing client requests from users accessing your services over the internet while simultaneously managing requests coming from other services or applications hosted within the cloud infrastructure. This comprehensive approach to traffic management empowers users to design more complex network topologies and enhance service delivery.
