Quick Answer
The answer is a misconfigured Microsoft Defender for Endpoint sensor on the devices. This sensor, the local agent installed on each endpoint, is the sole component responsible for collecting and reporting vulnerability data to Microsoft Defender XDR; if it is missing, disabled, or not communicating, the vulnerability data will simply never appear. On the Microsoft 365 Endpoint Administrator MD-102 exam, this question tests your understanding of the Defender for Endpoint data pipeline, specifically that the sensor is the source of truth for vulnerability information, not higher-level services like Intune or Sentinel. A common trap is confusing the sensor with management tools—Intune pushes policies but does not generate vulnerability data, and Sentinel only consumes it. Remember the memory tip: “No sensor, no sensor data”—the agent must be present and healthy for any vulnerability telemetry to flow.
This MD-102 practice question tests your understanding of protect devices. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 for Endpoint to manage endpoint security. They observe that some devices are not reporting vulnerability data to Microsoft Defender XDR. Which component is most likely misconfigured?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Microsoft Sentinel workspace
Why wrong: Sentinel ingests data but is not the source of vulnerability data.
Microsoft Defender for Endpoint sensor on the devices
The sensor collects vulnerability data; missing sensor stops reporting.
Intune MDM authority
Why wrong: MDM authority affects management, not vulnerability data collection.
Microsoft Purview compliance portal
Why wrong: Purview is for compliance, not endpoint vulnerability.
Answer choices
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 on the devices
Option A is correct: Microsoft Defender for Endpoint relies on its agent (sensor) to collect vulnerability data. If the sensor is not installed or running, vulnerability data won't be reported. Option B (Intune MDM) manages device configuration but not vulnerability reporting. Option C (Microsoft Purview) is for compliance and data loss prevention. Option D (Microsoft Sentinel) ingests data from Defender but is not the source.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Microsoft Sentinel workspace
Why it's wrong here
Sentinel ingests data but is not the source of vulnerability data.
Microsoft Defender for Endpoint sensor on the devices
Why this is correct
The sensor collects vulnerability data; missing sensor stops reporting.
Clue confirmation

Intune MDM authority
Why it's wrong here
MDM authority affects management, not vulnerability data collection.
Microsoft Purview compliance portal
Why it's wrong here
Purview is for compliance, not endpoint vulnerability.
Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
