SC-900 Practice Question: Describe the capabilities of Microsoft security solutions
This SC-900 practice question tests your understanding of describe the capabilities of microsoft security solutions. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 troubleshooting a Windows device that is reporting as non-compliant in Microsoft Intune. The exhibit shows the output of a PowerShell command run on the device. Based on the output, which component is likely misconfigured?
The PowerShell output displays the 'OnboardingState' property with a value of 0, which indicates the device is not onboarded to Microsoft Defender for Endpoint. This is the likely cause of the non-compliant status.
B
Antivirus protection
Why wrong: The output does not show any antivirus protection status; the relevant property is 'OnboardingState', not antivirus settings.
C
Antispyware protection
Why wrong: Similar to antivirus, antispyware protection is not referenced in the output. The focus is on the Defender for Endpoint sensor onboarding.
D
Microsoft Defender Antivirus real-time protection
Why wrong: Microsoft Defender Antivirus real-time protection is not indicated by the 'OnboardingState' property. The output specifically relates to Defender for Endpoint sensor configuration.
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 Endpoint sensor onboarding
The PowerShell output shows the 'OnboardingState' value is 0, which indicates the device is not onboarded to Microsoft Defender for Endpoint. Intune uses the Defender for Endpoint sensor as a compliance signal; if the sensor is not properly onboarded, the device will report as non-compliant regardless of other security settings.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Microsoft Defender for Endpoint sensor onboarding
Why this is correct
The PowerShell output displays the 'OnboardingState' property with a value of 0, which indicates the device is not onboarded to Microsoft Defender for Endpoint. This is the likely cause of the non-compliant status.

Why it's wrong here
Microsoft Defender Antivirus real-time protection is not indicated by the 'OnboardingState' property. The output specifically relates to Defender for Endpoint sensor configuration.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'onboarding state' with 'real-time protection' or 'antivirus status', but the PowerShell output explicitly shows the 'OnboardingState' property, which is unique to Microsoft Defender for Endpoint sensor configuration, not to Microsoft Defender Antivirus settings.
Trap categories for this question
Similar concept trap
Similar to antivirus, antispyware protection is not referenced in the output. The focus is on the Defender for Endpoint sensor onboarding.
Command / output trap
The output does not show any antivirus protection status; the relevant property is 'OnboardingState', not antivirus settings.
Detailed technical explanation
How to think about this question
The Defender for Endpoint sensor onboarding state is stored in the registry under 'HKLM\SOFTWARE\Microsoft\Windows Advanced Threat Protection\Status' and is set to 1 when the device is successfully onboarded via a configuration script or Intune policy. A value of 0 means the sensor has not been configured or the onboarding script failed, which prevents the device from sending telemetry to the Defender for Endpoint cloud service, breaking the compliance evaluation chain.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
