- A
Microsoft Defender for Cloud
Correct. Defender for Cloud includes CSPM and workload protection for AKS, offering both configuration recommendations and runtime threat detection for containers.
- B
Microsoft Sentinel
Why wrong: Sentinel is a SIEM/SOAR for aggregating logs and orchestrating responses. It can ingest Defender for Cloud alerts but is not the primary tool for native cluster protection.
- C
Microsoft Defender for Endpoint
Why wrong: Defender for Endpoint focuses on endpoint protection (workstations, mobile). While it can protect nodes in the cluster, it does not provide Kubernetes-specific posture management.
- D
Microsoft Defender for Cloud Apps
Why wrong: Defender for Cloud Apps protects cloud applications (SaaS) from threats and data exposure. It does not directly protect Kubernetes clusters.

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.
A company runs a production Kubernetes cluster in Azure. The security team needs to continuously monitor the cluster for misconfigurations, such as containers running with privileged access or secrets exposed in environment variables. They also want to detect runtime threats like crypto-mining containers. Which Microsoft security solution should they use?
Answer choices
Why each option matters
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
Microsoft Defender for Cloud provides Cloud Security Posture Management (CSPM) and Cloud Workload Protection Platform (CWPP) capabilities. It continuously assesses Kubernetes clusters against the CIS Kubernetes Benchmark, detecting misconfigurations like privileged containers and exposed secrets in environment variables, and uses behavioral analytics to detect runtime threats such as crypto-mining containers.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Microsoft Defender for Cloud
Why this is correct
Correct. Defender for Cloud includes CSPM and workload protection for AKS, offering both configuration recommendations and runtime threat detection for containers.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Microsoft Sentinel
Why it's wrong here
Sentinel is a SIEM/SOAR for aggregating logs and orchestrating responses. It can ingest Defender for Cloud alerts but is not the primary tool for native cluster protection.
When this WOULD be correct
An organization needs to aggregate security logs from multiple sources (e.g., Azure, on-premises, other clouds) and use advanced analytics to detect and respond to complex threats across the entire environment, including custom detection rules and automated incident response.
- ✗
Microsoft Defender for Endpoint
Why it's wrong here
Defender for Endpoint focuses on endpoint protection (workstations, mobile). While it can protect nodes in the cluster, it does not provide Kubernetes-specific posture management.
When this WOULD be correct
An exam question asking for a solution to protect endpoints (e.g., desktops, laptops, servers) from malware, fileless attacks, or advanced persistent threats, with requirements for endpoint detection and response (EDR) and antivirus capabilities.
- ✗
Microsoft Defender for Cloud Apps
Why it's wrong here
Defender for Cloud Apps protects cloud applications (SaaS) from threats and data exposure. It does not directly protect Kubernetes clusters.
When this WOULD be correct
A company wants to discover and control the use of shadow IT SaaS applications, enforce data loss prevention policies for cloud apps, and detect anomalous user behavior in Office 365 or other SaaS platforms.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The SC-900 exam frequently reuses these exact scenarios with slightly different constraints.
✓Microsoft Defender for CloudCorrect answer▾
Why this is correct
Correct. Defender for Cloud includes CSPM and workload protection for AKS, offering both configuration recommendations and runtime threat detection for containers.
✗Microsoft SentinelWrong answer — click to see why▾
Why this is wrong here
Microsoft Sentinel is a SIEM/SOAR solution for security analytics and threat intelligence, not a dedicated tool for continuous monitoring of Kubernetes misconfigurations or runtime threats like crypto-mining. Defender for Cloud provides native Kubernetes workload protection.
★ When this WOULD be the correct answer
An organization needs to aggregate security logs from multiple sources (e.g., Azure, on-premises, other clouds) and use advanced analytics to detect and respond to complex threats across the entire environment, including custom detection rules and automated incident response.
Why candidates choose this
Candidates may confuse Sentinel's broad security analytics capabilities with the specific Kubernetes workload protection offered by Defender for Cloud, or assume that any Microsoft security tool can handle container monitoring.
✗Microsoft Defender for EndpointWrong answer — click to see why▾
Why this is wrong here
Microsoft Defender for Endpoint focuses on endpoint devices (e.g., servers, workstations) and does not provide Kubernetes-specific misconfiguration monitoring or runtime threat detection for containers.
★ When this WOULD be the correct answer
An exam question asking for a solution to protect endpoints (e.g., desktops, laptops, servers) from malware, fileless attacks, or advanced persistent threats, with requirements for endpoint detection and response (EDR) and antivirus capabilities.
Why candidates choose this
Candidates may assume 'Defender for Endpoint' covers all security scenarios because of the broad 'Defender' branding, or they confuse container runtime protection with endpoint protection.
✗Microsoft Defender for Cloud AppsWrong answer — click to see why▾
Why this is wrong here
Microsoft Defender for Cloud Apps is a cloud access security broker (CASB) focused on SaaS applications, not on monitoring Kubernetes cluster configurations or runtime threats like crypto-mining containers.
★ When this WOULD be the correct answer
A company wants to discover and control the use of shadow IT SaaS applications, enforce data loss prevention policies for cloud apps, and detect anomalous user behavior in Office 365 or other SaaS platforms.
Why candidates choose this
Candidates may confuse 'cloud apps' with 'cloud workloads' and think Defender for Cloud Apps covers all cloud security, including Kubernetes, due to its broad name.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Microsoft Sentinel's log aggregation capabilities with the proactive, agent-based posture management and runtime detection that Defender for Cloud provides specifically for Kubernetes workloads.
Detailed technical explanation
How to think about this question
Defender for Cloud integrates with Azure Kubernetes Service (AKS) via the Azure Arc-enabled Kubernetes extension, deploying a DaemonSet that collects audit logs, security events, and runtime signals. It uses the Microsoft Threat Intelligence engine to compare container behavior against known indicators of compromise (IOCs) for crypto-mining, and applies the CIS Kubernetes Benchmark v1.6.1 to check for over 100 configuration rules, including those for Pod Security Policies and environment variable exposure.
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.
