Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company has a global web application deployed on Azure virtual machines in three separate Azure regions: West US, West Europe, and Southeast Asia. The application must automatically direct each user to the region that is geographically closest to the user's location in order to minimize latency. The solution must expose a single DNS name that does not change if regions are added or removed. The company does not need to offload SSL certificates or perform URL-based routing at the global level. Which Azure service should the company use to meet these requirements?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Azure Load Balancer
Azure Load Balancer distributes incoming traffic across healthy virtual machines within a single region at the transport layer (Layer 4). It cannot route traffic across multiple Azure regions based on geographic location, and it does not provide a single DNS name that points to multiple regions.
B
Best answer
Azure Traffic Manager
Azure Traffic Manager is a DNS-based traffic routing service that can direct users to the closest region using performance or geographic routing methods. It exposes a single DNS name, supports multi-region failover, and does not require SSL offloading or URL routing, making it the correct choice for this scenario.
C
Distractor review
Azure Application Gateway
Azure Application Gateway is a regional Layer 7 load balancer that provides HTTP/S routing, SSL termination, and Web Application Firewall (WAF) capabilities. It operates within a single region and is not designed for global DNS-based geographic routing across multiple regions.
D
Distractor review
Azure Front Door
Azure Front Door is a global HTTP/S load balancer and content delivery network that offers anycast-based routing, SSL offloading, caching, and WAF. While it can route traffic to the nearest region, it includes many features not required by the scenario (e.g., SSL offloading, caching), and the simpler DNS-based Traffic Manager is a more appropriate choice given the stated lack of need for those additional features.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

FAQ
Questions learners often ask
What does this AZ-900 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Azure Traffic Manager — Azure Traffic Manager is a DNS-based traffic load balancer that can route incoming traffic to the nearest available endpoint based on geographic location or performance metrics. It provides a single DNS name (e.g., myapp.trafficmanager.net) and can automatically detect endpoint health. The other services operate primarily within a single region (Azure Load Balancer and Azure Application Gateway) or include features like SSL offloading and caching that are not required in this scenario (Azure Front Door).
