Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Alert on a single failed login from any IP
Why it's wrong here
A single failure is not indicative of a brute force attack.
- ✓
Alert when more than 10 failed logins from the same IP occur within one minute
Why this is correct
This rule detects rapid successive failures, a common brute force pattern.
- ✗
Alert when a successful login occurs after midnight
Why it's wrong here
This may be suspicious but is not specific to brute force.
- ✗
Alert when a user logs in from a new geographic location
Why it's wrong here
This indicates possible account takeover but not necessarily brute force.
