MD-102 Protect devices Practice Question
Exhibit
Refer to the exhibit. Exhibit (KQL query from Microsoft Defender XDR): DeviceInfo | where Timestamp > ago(7d) | where DeviceName contains "CONTOSO-LAPTOP" | project Timestamp, DeviceName, OSPlatform, OSVersion, IsAzureADJoined, RiskScore | order by Timestamp desc
Refer to the exhibit. You run this KQL query in Microsoft Defender XDR to investigate a device. The result shows RiskScore = 0. What does this indicate about the device?
⚠ Common exam trap
The trap here is that candidates often misinterpret a RiskScore of 0 as an error or lack of enrollment, when in fact it is a valid state indicating no detected threats, and Microsoft uses this value to distinguish clean devices from those with unresolved risks.
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
✓
The device has no detected threats
In Microsoft Defender XDR, the RiskScore property (0–100) reflects the device's vulnerability level based on active threats and exposures. A RiskScore of 0 indicates that no threats or vulnerabilities have been detected on the device, meaning it is currently clean. This aligns with option D being correct because the absence of detected threats results in the lowest possible risk score.
