Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
High volume of failed login attempts followed by a successful login
Why this is correct
This often indicates a successful password spraying or brute force attack.
- ✗
Concurrent logins from different operating systems
Why it's wrong here
This is often a false positive due to mobile and desktop sync and is not a primary indicator of account takeover.
- ✓
Impossible travel (login from geographically distant locations in a short time)
Why this is correct
This is a classic signal of credential sharing or compromise.
- ✓
Login events occurring outside of established user work hours
Why this is correct
Anomalous login times are a primary behavioral indicator of account compromise.
- ✗
Accessing the account from a known VPN IP range
Why it's wrong here
VPN usage is common and does not inherently indicate account takeover.
