Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The user will be blocked only if the third IP is different from the first two.
The policy triggers when the count of different IPs for failed logins reaches 3 within 10 minutes. The action is to block the user. 'DifferentCount' means distinct IPs, not total attempts. So exactly 3 different IPs trigger it.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The policy will generate an alert but not block the user.
Why it's wrong here
The actions include 'Block', so it will block.
- ✗
The user will be blocked immediately after the third failed login from any IP.
Why it's wrong here
The condition is based on different IPs, not total attempts. If all attempts are from the same IP, it won't trigger.
- ✗
The user will be blocked after 10 minutes regardless of the number of IPs.
Why it's wrong here
The time window is 10 minutes, but the condition requires 3 different IPs within that window.
- ✓
The user will be blocked only if the third IP is different from the first two.
Why this is correct
The policy requires 3 distinct IP addresses; after the third distinct IP, the user is blocked.
