Quick Answer
The answer is that using Azure Firewall to enforce egress traffic rules for the AKS cluster is a valid consideration. This is correct because Azure Network Policy Manager (Azure NPM) is the required add-on that translates Kubernetes NetworkPolicy objects into Azure-specific configurations to filter pod-to-pod traffic; however, it does not handle outbound egress traffic to external services. For controlling egress, Azure Firewall is the native Azure solution that integrates with AKS to enforce outbound rules, complementing the pod-level restrictions managed by Azure NPM. On the AZ-500 exam, this distinction tests your understanding of the layered security model: Azure NPM enforces internal Kubernetes NetworkPolicy, while Azure Firewall manages external egress—a common trap is assuming Azure NPM alone covers all traffic directions. Remember the memory tip: “NPM for pods inside, Firewall for traffic outside.”
AZ-500 Secure networking Practice Question
This AZ-500 practice question tests your understanding of secure networking. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You are securing an Azure Kubernetes Service (AKS) cluster. You need to restrict network traffic between pods and to external services using Azure network policies. Which three of the following options are valid considerations or steps? (Choose three.)

Correct answer & explanation
✓
Enable the Azure Network Policy Manager (Azure NPM) when creating the AKS cluster.
Azure Network Policy Manager (Azure NPM) is a required add-on for enforcing Kubernetes NetworkPolicy objects in an AKS cluster. It translates Kubernetes network policies into Azure-specific configurations to filter pod-to-pod traffic. Without enabling Azure NPM (or an alternative like Calico), standard Kubernetes NetworkPolicy objects will not be enforced by Azure.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse NSGs with Kubernetes network policies, thinking NSGs can filter pod-to-pod traffic, but NSGs operate at the subnet level and cannot see pod IPs, making them ineffective for pod-level segmentation.
Detailed technical explanation
How to think about this question
Azure NPM works by intercepting traffic at the Linux iptables level on each AKS node, applying rules derived from Kubernetes NetworkPolicy objects. It supports both ingress and egress rules using pod and namespace selectors, and it integrates with Azure's underlying networking stack. In a real-world scenario, if you need to enforce strict micro-segmentation, you must ensure Azure NPM is enabled at cluster creation time, as it cannot be added later without recreating the cluster.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
