SC-900 Practice Question: Describe the capabilities of Microsoft security solutions
What is the primary purpose of Microsoft Defender for Cloud Apps?
⚠ Common exam trap
Candidates often confuse Defender for Cloud Apps with a general-purpose security tool, mistakenly thinking it monitors network traffic (Option A) or protects on-premises servers (Option C), when its focus is exclusively on cloud application security and data protection.

Correct answer & explanation
✓
Secure cloud applications and data
Microsoft Defender for Cloud Apps is a Cloud Access Security Broker (CASB) that provides visibility, data controls, and threat protection for cloud applications and data. Its primary purpose is to secure cloud apps (like Microsoft 365, Salesforce, or Dropbox) by enforcing policies, detecting anomalous behavior, and preventing data exfiltration, not to manage network traffic, mobile devices, or on-premises servers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Monitor network traffic
Why it's wrong here
While Microsoft Defender for Cloud (MDC) does offer network recommendations and integrates with Azure Network Watcher for some network visibility, its primary purpose extends beyond mere traffic monitoring. Dedicated network security tools like Azure Firewall, Network Security Groups (NSGs), or third-party Network Detection and Response (NDR) solutions are specifically designed for granular, real-time analysis and enforcement of network traffic policies, which is not MDC's core focus.
- ✗
Manage mobile devices
Why it's wrong here
Managing mobile devices, including their configuration, application deployment, and compliance, is the core function of Microsoft Intune, which is part of Microsoft Endpoint Manager. Microsoft Defender for Cloud, conversely, focuses on securing cloud workloads and environments across various cloud providers, not on endpoint management for mobile devices or traditional desktops.
- ✗
Protect on-premises servers
Why it's wrong here
While Microsoft Defender for Cloud can extend its protection to on-premises servers and other non-Azure resources through Azure Arc integration, its *primary* purpose is not solely or predominantly focused on on-premises infrastructure. Its core design and capabilities are centered on providing Cloud Security Posture Management (CSPM) and Cloud Workload Protection Platform (CWPP) for cloud-native and hybrid environments, with a strong emphasis on Azure and other public clouds.
- ✓
Secure cloud applications and data
Why this is correct
Microsoft Defender for Cloud's primary purpose is to provide comprehensive security posture management and threat protection across cloud environments, including Azure, AWS, and GCP. This encompasses securing cloud applications, data, virtual machines, containers, databases, and other services by identifying misconfigurations, recommending security improvements, and detecting and responding to threats. It acts as a Cloud Workload Protection Platform (CWPP) and Cloud Security Posture Management (CSPM) solution, ensuring the overall security of cloud-native assets.
