Quick Answer
The answer is to integrate Azure Container Registry with Microsoft Defender for Containers, use Azure Key Vault with managed identities for secret injection, and configure a service mesh like Istio on AKS for mutual TLS. This trio directly satisfies the security mandate because Defender for Containers automatically scans container images for vulnerabilities at rest and on push, ensuring no known flaws enter your AKS or ACI workloads. Azure Key Vault, accessed via a managed identity, injects secrets at runtime rather than baking them into image layers, eliminating the risk of secret exposure in registries. Finally, a service mesh enables encrypted mTLS between pods, securing east-west traffic without application changes. On the AZ-500 exam, this question tests your ability to map Azure security services to specific container lifecycle stages—build, deploy, and run. A common trap is choosing Azure Firewall for traffic encryption, but that only protects north-south traffic, not pod-to-pod. Memory tip: “Scan, Inject, Encrypt” for images, secrets, and traffic.
AZ-500 Secure compute, storage, and databases Practice Question
This AZ-500 practice question tests your understanding of secure compute, storage, and databases. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Your organization is planning to use Azure Container Instances (ACI) and Azure Kubernetes Service (AKS) for running containerized workloads. The security policy mandates that container images be scanned for vulnerabilities, secrets never be stored in image layers, and network traffic between containers be encrypted. Which three of the following should you implement? (Choose three.)

Correct answer & explanation
✓
Integrate Azure Container Registry (ACR) with Microsoft Defender for Containers to scan images on push.
Integrating ACR with Microsoft Defender for Containers enables vulnerability scanning of container images at rest and on push, ensuring images are free from known vulnerabilities before deployment. This directly addresses the mandate to scan images for vulnerabilities.
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 might think NSGs or Kubernetes Secrets provide encryption or secure secret storage, but NSGs only filter traffic (no encryption) and Kubernetes Secrets are not encrypted by default, so they fail the mandates for encrypted traffic and secret-free image layers.
Detailed technical explanation
How to think about this question
Microsoft Defender for Containers uses the Qualys scanner to perform deep image layer analysis against CVE databases, and can trigger automated actions like blocking deployment of vulnerable images. The AKS Secrets Store CSI Driver integrates with Azure Key Vault via a CSI volume, allowing pods to mount secrets as files or environment variables without ever writing them to the pod's image or etcd, thus preventing secret leakage in image layers. A service mesh like Istio or Azure Service Mesh implements mTLS by injecting sidecar proxies (Envoy) that handle encryption and authentication at the L7 layer, ensuring all pod-to-pod traffic is encrypted without application code changes.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
