Full question →hardmultiple choiceObjective-mapped
A company deploys a multi-tier web application on Azure VMs across availability zones. The web tier must have SSL termination, session persistence, and health probe monitoring. Additionally, all traffic must be inspected by a central firewall for compliance. The solution must be highly available. Which combination of Azure services should they implement?
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 Application Gateway (WAF) in front of web VMs, with Azure Firewall in a hub VNet for central inspection
Correct. Application Gateway handles web traffic with SSL and session persistence; Azure Firewall inspects all traffic centrally.
B
Distractor review
Azure Load Balancer (Standard) in front of web VMs, with a third-party Network Virtual Appliance (NVA) for inspection
Load Balancer does not provide SSL termination or session persistence; NVA adds management overhead.
C
Distractor review
Azure Front Door in front of web VMs, with Azure Firewall for inspection
Front Door is a global load balancer; it does not route traffic through a VNet firewall for internal inspection.
D
Distractor review
Azure Traffic Manager + Azure Application Gateway
Traffic Manager provides DNS-level routing but no inspection; this combination lacks central firewall inspection.
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 (WAF) in front of web VMs, with Azure Firewall in a hub VNet for central inspection — Azure Application Gateway provides SSL termination, session persistence (cookie-based affinity), and health probes for HTTP/S traffic. To inspect traffic centrally (including non-web traffic), you deploy Azure Firewall in the hub VNet. Azure Load Balancer does not provide SSL termination or native session persistence. Azure Front Door is global and does not inspect internal traffic. Traffic Manager is DNS-based and does not inspect traffic.
