Question

Which of the following is often used to keep the number of alerts to a manageable level when establishing a process to track and analyze violations?

Options

  • ALog retention
  • BLog rotation
  • CMaximum log size
  • DThreshold value

Explanation

A threshold value is a parameter that defines the minimum or maximum level of a metric or event that triggers an alert. For example, a threshold value can be set to alert when the number of failed login attempts exceeds 10 in an hour, or when the CPU usage drops below 20% for more than 15 minutes. By setting a threshold value, the process can filter out irrelevant or insignificant alerts and focus on the ones that indicate a potential problem or anomaly. A threshold value can help to reduce the noise and false positives in the alert system, and improve the efficiency and accuracy of the analysis.
