Question 520
A compliance analytics team checks daily privacy and completeness indicators. A reviewer sees that engineers chose Tune threshold, schedule and deduplication policy based on baseline metrics. To verify A noisy anomaly threshold raises hundreds of repeated false alarms, what should the reviewer observe?
Explanation
Correct Answer
The same benign variance no longer floods the channel while true anomalies alert directly measures whether Tune threshold, schedule and deduplication policy based on baseline metrics achieved the requirement “A noisy anomaly threshold raises hundreds of repeated false alarms.” It checks the operating result rather than just a configured resource name.
Incorrect Answers
An alert notification fires when the result crosses the configured threshold would demonstrate the separate action Create a Lakehouse/SQL alert on the scheduled aggregate query, which addresses “A daily row-count threshold breach should notify the data steward automatically.” It does not verify the requirement “A noisy anomaly threshold raises hundreds of repeated false alarms” following Tune threshold, schedule and deduplication policy based on baseline metrics.
This signal belongs to the adjacent case “A cost anomaly occurs during a period of high workload retries,” whose remedy is Correlate spend time series with Jobs run and retry records. The observed result for the present requirement is The same benign variance no longer floods the channel while true anomalies alert.
That observation is a valid indicator for “A streaming sink occasionally retries the same batch after transient errors” when using Correlate batch IDs and sink commit logs across retries. The scenario instead tests “A noisy anomaly threshold raises hundreds of repeated false alarms”; the relevant result is The same benign variance no longer floods the channel while true anomalies alert.
