Quick Answer
The correct answer is Smart Lockout, as it is Microsoft’s recommended feature to protect against password spray attacks in Microsoft Entra ID. Unlike simple account lockout policies, Smart Lockout uses adaptive logic to differentiate between a legitimate user and an attacker by analyzing the sign-in pattern, IP address, and history of failed attempts—locking out the bad actor after a threshold while allowing the real user to continue trying. On the MS-102 exam, this question tests your understanding of Entra ID’s built-in threat protections; a common trap is confusing Smart Lockout with Conditional Access policies or brute-force detection, but remember that Smart Lockout is specifically designed for password spray scenarios where attackers try common passwords across many accounts. For a memory tip, think “Smart Lockout = Smart Distinction” because it distinguishes between a spray and a legitimate typo, keeping your users productive while blocking the spray.

Your company uses Microsoft Entra ID and wants to use Microsoft's recommendation to protect against password spray attacks. Which feature should you enable?
Smart Lockout
Smart Lockout locks accounts after repeated failed attempts.
Identity Protection
Why wrong: Identity Protection detects risky sign-ins but does not lock out.
Password Hash Synchronization
Why wrong: PHS syncs passwords, not lockout.
Multifactor Authentication
Why wrong: MFA adds a second factor but does not prevent password spray.

Correct answer & explanation
Smart Lockout
Smart Lockout is Microsoft's recommended feature to protect against password spray attacks because it intelligently locks out bad actors after a threshold of failed attempts while allowing legitimate users to continue. It uses adaptive logic to distinguish between real users and attackers by considering the sign-in pattern and IP address, making it the correct choice for this specific threat.
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.
Smart Lockout
Why this is correct
Smart Lockout locks accounts after repeated failed attempts.
Related concept

Identity Protection
Why it's wrong here
Identity Protection detects risky sign-ins but does not lock out.
Password Hash Synchronization
Why it's wrong here
PHS syncs passwords, not lockout.
Multifactor Authentication
Why it's wrong here
MFA adds a second factor but does not prevent password spray.
Common exam traps
The trap here is that candidates often confuse Identity Protection (which detects risky sign-ins) with the direct mitigation feature Smart Lockout, or they assume MFA alone is sufficient to stop password spray attacks, when in fact Smart Lockout is the specific Microsoft-recommended control for this attack vector.
Detailed technical explanation
Smart Lockout uses a combination of failed attempt count and time window (default 10 failed attempts in 30 minutes) to trigger a lockout, but it also considers the sign-in velocity and familiar location to avoid locking out legitimate users. Under the hood, it leverages machine learning to model normal user behavior, so a user who mistypes their password occasionally will not be locked out, while an attacker spraying thousands of passwords across multiple accounts will be blocked. In a real-world scenario, if an attacker uses a botnet with distributed IPs, Smart Lockout still detects the pattern across accounts and applies a global lockout threshold.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
