The correct answer is a Conditional Access policy with the sign-in risk condition because this is the only Microsoft Entra ID policy that can automatically block sign-ins from anonymous IP addresses by evaluating real-time risk signals from Microsoft’s threat intelligence. When a sign-in originates from an anonymous proxy or Tor network, Entra ID assigns a high sign-in risk level, and a Conditional Access policy configured to block access when that risk threshold is met enforces the block without user intervention. On the MS-102 exam, this question tests your ability to distinguish between detection and remediation—Identity Protection can detect anonymous IP sign-ins but cannot block them, while Conditional Access provides the enforcement action. A common trap is confusing sign-in risk with user risk; remember that anonymous IP addresses are a sign-in risk factor, not a user behavior pattern. Memory tip: “Sign-in risk blocks the source, user risk blocks the account.”
MS-102 Practice Question: Manage security and threats by using Microsoft Defender XDR
This MS-102 practice question tests your understanding of manage security and threats by using microsoft defender xdr. 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.
You are a security administrator. You need to configure a policy that automatically blocks sign-ins from anonymous IP addresses for all users in your Microsoft 365 tenant. Which policy should you configure in Microsoft Entra ID?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Conditional Access policy with sign-in risk condition
Option C is correct because Conditional Access policies can block anonymous IP sign-ins. Option A is wrong because Identity Protection detects but doesn't block. Option B is wrong because password protection doesn't control sign-in. Option D is wrong because it's for user risk.
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.
✗
Password protection policy
Why it's wrong here
Password protection prevents weak passwords, not sign-in from anonymous IPs.
✗
Conditional Access policy with user risk condition
Why it's wrong here
User risk is for compromised accounts, not sign-in from anonymous IP.
✓
Conditional Access policy with sign-in risk condition
Why this is correct
Sign-in risk includes anonymous IP address detection.

✗
Identity Protection user risk policy
Why it's wrong here
User risk policy reacts to compromised accounts, not anonymous IPs.
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.
Detailed technical explanation
How to think about this question
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.
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.
Use explanations to understand the rule behind the answer.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
