A company has a hub-spoke network topology in Azure. They need to inspect and filter all traffic flowing between spoke virtual networks for malicious content and require that the inspection is stateful. Which Azure-native service should they deploy in the hub virtual network to meet this requirement?

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 Firewall

Azure Firewall provides stateful inspection and can filter traffic between spoke VNets when configured as a hub. It supports network and application rules, including threat intelligence-based filtering.

B

Distractor review

Network Security Groups (NSG) on the peering connections

NSGs are stateful for individual flows but cannot inspect or filter traffic at the peering level effectively. They are also limited to Layer 3/4 and cannot provide application-layer inspection.

C

Distractor review

Azure Application Gateway with WAF

Application Gateway is a Layer 7 load balancer with Web Application Firewall (WAF) for HTTP/HTTPS traffic. It does not handle general inter-VNet traffic.

D

Distractor review

Azure DDoS Protection Standard

DDoS Protection protects against distributed denial-of-service attacks at the network layer but does not inspect or filter normal traffic between VNets.

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-500 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 Firewall — Azure Firewall is a fully stateful firewall as a service that can inspect and filter traffic between virtual networks. It supports network and application rules, and can be deployed in a hub VNet to route inter-spoke traffic through it. NSGs on peering connections are not stateful for traffic across peering and cannot inspect application-layer content. Application Gateway with WAF is for web traffic only and requires a specific listener. DDoS Protection only mitigates volumetric attacks, not application-level filtering.
