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

How does Azure Traffic Manager reduce latency?

1. It chooses only the fastest networks between endpoints.

2. It chooses the endpoint that's closest to the user's DNS server.

3. It caches content, similar to how content delivery networks work.

4. It optimizes routing based on traffic patterns.

The correct answer is: It chooses the endpoint that's closest to the user's DNS server.

Azure Traffic Manager reduces latency by choosing the endpoint that is closest to the user's DNS server. When a user sends a request, Traffic Manager uses various routing methods to direct the request to the nearest available endpoint, considering the geographical location of the user. This geographic awareness helps minimize the distance that the data needs to travel, leading to faster response times and improved performance. The other options relate to different concepts in networking and performance. While caching content is a key function of content delivery networks, it is not a feature of Traffic Manager. Similarly, optimizing routing based on traffic patterns generally relates to network management strategies rather than the specific functions of Traffic Manager. Additionally, while selecting the fastest networks is an important aspect of network infrastructure, Traffic Manager specifically focuses on endpoint selection based on proximity, rather than network speed.
