The answer is Microsoft Defender for Cloud with the Defender for Containers plan. This is correct because Defender for Containers provides integrated vulnerability scanning of container images, runtime threat detection for AKS clusters, and automated alert generation for suspicious activities, all within a single, unified security solution. On the Microsoft Cybersecurity Architect exam, this question tests your understanding of how Defender for Cloud’s plan-based architecture maps to specific container security requirements, with a common trap being to confuse Azure Security Center (now legacy) or Azure Policy with runtime security capabilities. Remember that image scanning and runtime protection are unique to the Defender for Containers plan, not to configuration enforcement tools like Azure Policy. A useful memory tip: think “Containers need both scan and run” — Defender for Containers covers the full lifecycle from image to runtime.
SC-100 Design security solutions for infrastructure Practice Question
This SC-100 practice question tests your understanding of design security solutions for infrastructure. 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 designing a security solution for containers running on Azure Kubernetes Service (AKS). The requirements include: scanning container images for vulnerabilities, enforcing runtime security, and generating alerts for suspicious activities. Which combination of services should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Defender for Cloud with Defender for Containers plan
Option B is correct because Microsoft Defender for Containers provides image scanning and runtime threat detection integrated with AKS. Option A is wrong because Azure Security Center is now part of Defender for Cloud but the specific plan is Defender for Containers. Option C is wrong because Azure Policy can enforce configurations but not runtime security. Option D is wrong because Azure Container Registry provides image storage, not scanning.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Azure Security Center and Azure Policy
Why it's wrong here
Azure Security Center is now Defender for Cloud; runtime security requires Defender for Containers.
✗
Azure Container Registry and Azure Monitor
Why it's wrong here
No vulnerability scanning or runtime security.
✗
Azure Policy and Azure Firewall
Why it's wrong here
No runtime threat detection.
✓
Microsoft Defender for Cloud with Defender for Containers plan
Why this is correct
Provides image scanning, runtime security, and alerts.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.

Variation 1. You are designing a security solution for containers in Azure Kubernetes Service (AKS). The solution must scan container images for vulnerabilities before deployment and enforce runtime security. Which combination of Microsoft Defender for Cloud features should you enable?
medium
✓ A.Microsoft Defender for Containers
B.Microsoft Defender for App Service
C.Microsoft Defender for Cloud regulatory compliance dashboard
D.Microsoft Defender for Servers
Why A: Option B is correct because Defender for Containers provides vulnerability assessment for images and runtime threat detection for AKS clusters. Option A is wrong because Defender for Servers is for VMs, not containers. Option C is wrong because Defender for App Service protects web apps, not containers. Option D is wrong because Defender for Cloud's regulatory compliance does not provide vulnerability scanning or runtime protection.
