AA moderate to high likelihood of anomaly
BA low likelihood of anomaly
CThe number of anomalies detected
DThe job execution time in seconds
Step-by-Step Solution
Solution:
  1. Step 1: Understand anomaly score scale

    Elasticsearch anomaly scores range from 0 to 100, where higher means more anomalous.
  2. Step 2: Interpret score 75

    A score of 75 is considered moderately high, indicating a likely anomaly.
  3. Final Answer:

    A moderate to high likelihood of anomaly -> Option A
  4. Quick Check:

    Anomaly score 75 = Moderate-high anomaly [OK]
Quick Trick: Higher anomaly score means more unusual data [OK]
Common Mistakes:
MISTAKES
  • Thinking score is count of anomalies
  • Confusing score with time or duration
