Microsoft Azure Architect Design (AZ-301) Practice Exam

Azure Traffic Manager is primarily used to manage DNS traffic across various Azure regions, which allows for the efficient distribution of network traffic to different endpoints based on specific routing methods. This service enhances the availability and responsiveness of applications by directing user requests to the best possible endpoint—whether that be a different Azure region or even a different cloud provider—based on factors such as performance, geographic location, or availability.

By using Traffic Manager, you can ensure that your applications are highly available and that users experience minimal latency, as the traffic is routed intelligently. This capability is crucial for organizations that require global reach and resilience in their web applications.

Other options, while relevant to cloud services, do not accurately describe the primary function of Azure Traffic Manager. Services related to firewalls, data compression, or real-time database replication serve distinct purposes in cloud architectures, but they are not the core function of Traffic Manager, which is fundamentally about DNS management and traffic routing.
