Which of the following is NOT a standard Windows event severity level?

• A. Error
• B. Warning
• C. Information
• D. Critical

Answer: (D)

Understanding Windows Event Log severities: Windows uses three primary levels to describe how serious an event is—Error for failures, Warning for potential issues, and Information for routine messages. These cover the standard, built-in severities you’ll see in Event Viewer. There are also auditing types like Success Audit and Failure Audit, which indicate the outcome of an audited action rather than a severity level.

Critical isn’t part of that standard set. It’s not defined as a Windows Event Log severity, so it’s not used to categorize standard events in the Windows logging system. That’s why this option is the one that isn’t a standard Windows event severity level.
