The answer is to create a dynamic device group in Microsoft Entra ID using a rule that includes device.securityTags with the tag 'HighThreat'. This is correct because Microsoft Entra ID supports dynamic membership rules based on device attributes, and when Microsoft Defender for Endpoint (MDE) assigns a threat level, it writes the corresponding security tag directly to the device object in Entra ID. The rule `(device.securityTags -any (_ -eq "HighThreat"))` then dynamically populates the group with all devices at that threat level, allowing you to target them with a conditional access compliance policy that forces non-compliance. On the MD-102 exam, this tests your understanding of how MDE threat data flows into Entra ID for dynamic grouping, a common trap is confusing MDE machine groups (which are for Defender portal management, not compliance) with Entra ID dynamic groups. Remember the memory tip: "Tag, then bag" — MDE tags the device in Entra, then your dynamic rule bags it into the group.
MD-102 Protect devices Practice Question
This MD-102 practice question tests your understanding of protect devices. 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.
Your organization uses Microsoft Defender for Endpoint (MDE) and Microsoft Intune. You need to create a device group that dynamically includes all devices with a threat level of 'High' from MDE. You then plan to apply a compliance policy to force those devices to be non-compliant. Which method should you use to create the dynamic group?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a dynamic device group in Microsoft Entra ID using a rule that includes device.securityTags with the tag 'HighThreat'
Option A is correct because dynamic device groups in Microsoft Entra ID can use rules based on device properties, including MDE threat level. Option B is wrong because MDE machine groups are not used for compliance policies. Option C is wrong because Intune groups cannot be dynamic based on MDE threat level. Option D is wrong because security groups are static.
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.
✗
Create a security group in Microsoft Entra ID and manually add devices with high threat
Why it's wrong here
Manual management is not dynamic and not recommended.
✓
Create a dynamic device group in Microsoft Entra ID using a rule that includes device.securityTags with the tag 'HighThreat'
Why this is correct
Microsoft Defender for Endpoint can tag devices with threat levels, and Entra ID dynamic groups can use these tags.

✗
Create a device group in Microsoft Defender for Endpoint and assign it to a compliance policy
Why it's wrong here
MDE machine groups cannot be assigned to Intune compliance policies.
✗
Create a dynamic device group in Microsoft Intune using a rule based on threat level
Why it's wrong here
Intune does not support dynamic groups based on MDE threat level.
Common exam traps
Common exam trap: answer the scenario, not the keyword
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.

TExam Day Tips
→Underline the problem statement mentally.
→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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
