Which three primary event logs should be monitored?

Monitoring the primary event logs is essential for maintaining the health and security of a system. The correct answer includes the Application, Security, and System logs because each of these plays a critical role in tracking different types of events.

The Application log records events related to the operation of applications running on the system. This includes errors, warnings, and informational events that can help administrators understand application behavior and troubleshoot issues.

The Security log is vital for monitoring security-related events, such as login attempts, resource access, and any potential security incidents. By examining this log, administrators can detect unauthorized access and other security threats, ensuring the integrity of the system.

The System log captures events related to the operating system, including errors and other significant system notifications. This log helps in identifying system failures and performance issues, allowing for quick remediation to avoid downtime.

In contrast, the other options include various logs that do not represent the three primary logs commonly monitored for comprehensive system oversight. For instance, the Setup and Service logs, while important for specific purposes, do not provide the same breadth of information as the Application, Security, and System logs in terms of monitoring system performance and security.
