- A
Azure Load Balancer
Why wrong: 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
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
Azure Application Gateway
Why wrong: 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
Azure Front Door
Why wrong: 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.
Quick Answer
The answer is Azure Traffic Manager, which is the correct choice because it uses DNS-based global load balancing with a Performance routing method to direct users to the geographically closest Azure region, minimizing latency while exposing a single, unchanging DNS name even when endpoints are added or removed. This solution perfectly fits the requirement to avoid SSL offloading or URL-based routing, as Traffic Manager operates purely at the DNS level without inspecting traffic content. On the AZ-900 exam, this scenario tests your understanding of the difference between global load balancing services: Traffic Manager handles DNS-level routing based on latency or geography, whereas Azure Front Door adds application-layer features like SSL termination and URL path routing, which are explicitly not needed here. A common trap is choosing Front Door because it also offers global routing, but remember: if the question says no SSL offload or URL-based routing, it’s Traffic Manager. Memory tip: “Traffic Manager = DNS only; Front Door = full application delivery.”
AZ-900 Describe Azure architecture and services Practice Question
This AZ-900 practice question tests your understanding of describe azure architecture and services. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?

Correct answer & explanation
Azure Traffic Manager
Azure Traffic Manager is a DNS-based traffic load balancer that can route users to the closest regional endpoint based on geographic location using the 'Performance' routing method. It exposes a single DNS name (e.g., myapp.trafficmanager.net) that remains constant even when endpoints are added or removed, and it does not require SSL offloading or URL-based routing, matching the requirements exactly.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Azure Traffic Manager
Why this is correct
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.

Azure Application Gateway
Why it's wrong here
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.
- ✗
Azure Front Door
Why it's wrong here
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 traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Traffic Manager (DNS-based, Layer 4) with Azure Front Door (Layer 7, HTTP/HTTPS), and choose Front Door because it also supports global routing, but the question explicitly states no SSL offload or URL-based routing is needed, making Traffic Manager the correct and simpler choice.

Detailed technical explanation
How to think about this question
Azure Traffic Manager uses the DNS resolution process to direct client traffic; when a client queries the Traffic Manager DNS name, it returns the IP address of the endpoint with the lowest latency based on the client's source IP and the configured routing method (e.g., Performance). Under the hood, Traffic Manager does not inspect HTTP headers or terminate SSL—it simply resolves DNS to the best endpoint, which is why it is ideal for scenarios where only geographic proximity and a stable DNS name are needed. A real-world scenario is a global e-commerce site that wants to direct users to the nearest regional web app without adding complexity like SSL termination at the global level.
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.
TExam Day Tips
- 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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.

Variation 1. A company hosts a public-facing web application on Azure Virtual Machines in two separate Azure regions for disaster recovery. The application's domain is managed by a third-party registrar. The company needs a solution that can route user traffic to the nearest healthy regional endpoint based on geographic location and provides automatic failover if an entire region becomes unavailable. The solution should not inspect or modify the HTTP traffic (no SSL termination or web application firewall). Which Azure service should the company use?
medium- A.Azure Load Balancer
- B.Azure Application Gateway
- ✓ C.Azure Traffic Manager
- D.Azure Front Door
Why C: Azure Traffic Manager is a DNS-based traffic load balancer that routes incoming DNS requests to the nearest healthy regional endpoint based on geographic location or latency. It supports automatic failover by monitoring endpoint health and redirecting traffic if an entire region becomes unavailable, and it operates at the DNS level without inspecting or modifying HTTP traffic, so no SSL termination or web application firewall is involved.
