The answer is a failed network login. This is correct because the Windows logon type events are categorized by numeric codes, and Logon Type 3 specifically indicates a network logon, meaning the connection attempt came from a remote system rather than directly at the console. Since the event also shows a failure status, it is a failed network login, not a successful one. On the ISC2 Certified in Cybersecurity CC exam, you will often see a security log exhibit with a Logon Type value and be asked to interpret the event; a common trap is confusing Logon Type 3 with a local logon (which would be Type 2 or 10) or assuming a failure means an account lockout. Remember the memory tip: “Type 3 is the network key”—if you see a 3, think remote connection, and always check the failure code to distinguish between a failed login and a lockout event.
ISC2 CC Security Operations Practice Question
This CC practice question tests your understanding of security operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Exhibit
Event ID 4625: An account failed to log on. Subject: Security ID: NULL_SID, Account Name: - , Account Domain: -; Logon Type: 3; Account For Which Logon Failed: Security ID: NULL SID, Account Name: administrator; Failure Reason: Unknown user name or bad password; Workstation Name: PC123; Source Network Address: 10.0.0.99;
Event ID 4625: An account failed to log on. Subject: Security ID: NULL_SID, Account Name: - , Account Domain: -; Logon Type: 3; Account For Which Logon Failed: Security ID: NULL SID, Account Name: administrator; Failure Reason: Unknown user name or bad password; Workstation Name: PC123; Source Network Address: 10.0.0.99;
A
Account lockout
Why wrong: Account lockout events have different Event ID (e.g., 4740).
B
Successful remote login
Why wrong: The event indicates failure, not success.
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
Option C is correct because Logon Type 3 indicates a network logon (remote connection). Option A is wrong because it's a failed logon. Option B is wrong because Logon Type 3 is remote, not local (local is Type 2 or 10). Option D is wrong because there is no account lockout event.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
