Full question →mediummultiple choiceObjective-mapped
A company plans to deploy multiple virtual machines (VMs) across two Azure regions for high availability. The VMs will host a stateless web application that must be accessible via a single DNS endpoint. The solution must automatically route traffic to the nearest region with available capacity and provide failover if a region becomes unhealthy. Which Azure service should they 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
Best answer
Azure Traffic Manager
Traffic Manager uses DNS to route users to the nearest or best-performing region and supports automatic failover when an endpoint becomes unhealthy.
B
Distractor review
Azure Front Door
Front Door provides global load balancing and SSL offload but is unnecessary for the stated requirement for this simple requirement; Traffic Manager is simpler and more cost-effective for DNS-based routing.
C
Distractor review
Azure Load Balancer
Load Balancer operates within a single region and cannot route traffic across regions.
D
Distractor review
Azure Application Gateway
Application Gateway is a regional layer-7 load balancer and does not provide multi-region routing.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this AZ-305 question test?
Static NAT maps one inside address to one outside address.
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 enables you to distribute traffic to public-facing endpoints across global Azure regions. It provides automatic failover and performance-based routing, which suits this scenario. Azure Front Door is an application delivery network that also provides global load balancing but includes features like SSL offload and path-based routing, which are not required here. Azure Load Balancer operates within a single region. Azure Application Gateway is a regional layer-7 load balancer.
