Detailed Answer in Step-by-Step Solution:

Objective: Minimize false alarms in OCI Anomaly Detection.

Understand FAP: False Alarm Probability—lower FAP means fewer false positives.

Evaluate Options:

A: High FAP—Increases false alarms—incorrect.

B: Low FAP—Reduces false alarms—correct.

C: Zero FAP—Unrealistic; risks missing true anomalies.

D: Function—Vague, not a direct setting.

Reasoning: Low FAP balances sensitivity and false positives— aligns with goal.

Conclusion: B is correct.

OCI Anomaly Detection documentation states: “Set a low False Alarm Probability (FAP) to minimize false positives, though too low (e.g., zero) may miss anomalies.” B fits the goal—high (A) increases errors, zero (C) is impractical, and function (D) isn’t specified.
