SC-100 Practice Question: Design security operations, identity, and compliance capabilities
This SC-100 practice question tests your understanding of design security operations, identity, and compliance capabilities. 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.
A company uses Microsoft Defender XDR and wants to ensure that all devices are reporting to the service. They notice that some devices are not appearing in the device inventory. Which log source should they check first to troubleshoot?

Correct answer & explanation
✓
Microsoft Defender for Endpoint deployment log (MDEClientAnalyzer)
The MDEClientAnalyzer tool generates a detailed deployment log that specifically captures the onboarding and communication status between the device and the Microsoft Defender for Endpoint (MDE) cloud service. When devices are missing from the device inventory, this log is the first place to check because it reveals whether the sensor is installed, registered, and successfully sending telemetry. Other logs, like Intune enrollment or Windows Defender operational logs, do not directly track MDE sensor connectivity or onboarding failures.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse device enrollment (Intune) with sensor onboarding (Defender for Endpoint), assuming that if a device is managed by Intune, it must automatically report to Defender XDR, but the two processes are independent and require separate troubleshooting paths.
Trap categories for this question
Command / output trap
Intune logs show device management, not Defender onboarding.
Detailed technical explanation
How to think about this question
The MDEClientAnalyzer (MDEClientAnalyzer.cmd) runs a series of connectivity tests including DNS resolution to the MDE cloud endpoints (e.g., *.events.data.microsoft.com), certificate validation, and HTTP/HTTPS handshake verification. It also parses the SenseIR event logs and the Microsoft-Windows-Sense/Operational log to check if the sensor is running and has successfully registered with the tenant. In a real-world scenario, a device may appear in Intune but not in MDE inventory because of a proxy misconfiguration or a stale certificate, which the MDEClientAnalyzer output will explicitly flag.
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.
