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

Azure Traffic Manager reduces latency primarily by selecting the endpoint that is closest to the user's DNS server. When a user makes a request, Traffic Manager utilizes the DNS resolution process to determine which of the available endpoints can respond the quickest based on geographic proximity. The principle behind this is that shorter distances typically result in lower latency, helping to ensure that users connect to the most responsive service region.

This approach optimally directs the traffic to the location that can fulfill the request faster, thereby enhancing the overall user experience. By optimizing the selection process through DNS queries, Traffic Manager effectively minimizes the time it takes for users to access resources.

Other strategies such as choosing the fastest networks or caching content have differing functions and are more aligned with other Azure services like Azure CDN, which specifically focuses on content delivery. Prioritizing traffic based on bandwidth is another different management technique that doesn't directly relate to reducing latency through intelligent endpoint selection in the context of Traffic Manager.
