Full question →easymultiple choiceObjective-mapped
A company plans to deploy a web application on Azure VMs across multiple availability zones. They need to distribute incoming HTTP traffic across the VMs and provide health probes. Which Azure load balancing solution should they use?
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 operates at layer 4 (TCP/UDP) and does not provide HTTP-level features like health probes based on HTTP status or SSL termination.
B
Best answer
Azure Application Gateway
Application Gateway is a layer 7 load balancer that supports HTTP/HTTPS, health probes, SSL offloading, and can distribute traffic across VMs in availability zones.
C
Distractor review
Azure Traffic Manager
Traffic Manager is a DNS-based traffic router that directs traffic to different endpoints based on routing methods, but it does not distribute traffic to individual VMs or perform health probes at the application layer.
D
Distractor review
Azure Front Door
Front Door is a global load balancer and CDN; while it supports health probes, it is designed for multi-region scenarios and adds unnecessary cost for a single-region deployment.
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 Application Gateway — Azure Application Gateway is a layer 7 load balancer that supports HTTP/HTTPS traffic, health probes, and SSL termination. It is designed for web applications. Azure Load Balancer works at layer 4 and does not handle HTTP-specific features. Traffic Manager is DNS-based and does not provide direct health probing for individual VMs. Azure Front Door is a global load balancer but is unnecessary for the stated requirement for a single-region deployment with availability zones.
