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
✓
Failed network login
The event shows a failed network logon (Logon Type 3) with a failure status code. Option A is incorrect because an account lockout event would have a different event ID (e.g., 4740), not a Logon Type 3 failure. Option B is incorrect because the event indicates a failure (e.g., status 0xC000006D), not a successful login. Option D is incorrect because Logon Type 3 indicates a network logon, whereas a local logon would be Type 2 or 10.
