Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
A company plans to migrate a legacy web application to Azure. The application runs on multiple Windows virtual machines (VMs) in an availability set. The VMs must be exposed to the internet via a single endpoint that performs SSL termination and health checks. The load-balancing solution must preserve the original client IP address for logging purposes. Which Azure service should the company 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 (Standard)
Load Balancer operates at layer-4 and cannot offload SSL termination. It is suitable for non-HTTP(S) traffic or scenarios where SSL is handled elsewhere.
B
Best answer
Azure Application Gateway v2
Application Gateway is a layer-7 load balancer that provides SSL termination, health probes, and preserves the client IP address via X-Forwarded-For headers.
C
Distractor review
Azure Traffic Manager
Traffic Manager is a DNS-based traffic router. It does not handle SSL termination or direct traffic distribution to VMs; it only directs clients to endpoints based on routing methods.
D
Distractor review
Azure Front Door
Front Door is a global layer-7 load balancer with WAF capabilities. While it can perform SSL termination, it is designed for global distribution and adds unnecessary cost and complexity 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 v2 — Azure Application Gateway is a layer-7 load balancer that supports SSL termination, cookie-based session affinity, health probes, and preserves the original client IP via X-Forwarded-For headers. Azure Load Balancer (Standard) operates at layer-4 and does not provide SSL offloading. Azure Traffic Manager is a DNS-level traffic routing service, not a direct load balancer. Azure Front Door is a global load balancer with WAF, but for a single-region deployment, Application Gateway is the appropriate choice.
