Question 870
A multi-device security analysis reveals this requirement: A threat chart's numeric counts change after a parser update because the normalized severity field now stores values in a different scale. Which statement describes the decisive system dependency?
Explanation
Correct Answer
Changing normalized severity representation alters grouping even when the number of raw detections has not changed. This behavior determines the engineering decision. The appropriate action is: Inspect parser normalization and update the dataset's severity mapping to the current documented field semantics. Verify success by checking: Old and new sample log formats map to the expected categories and total event count is conserved.
Incorrect Answers
The action “Missing or changed raw fields propagate as null through report SQL unless a supported fallback is defined” addresses a separate source case: A report chart shows null values for source usernames after a FortiGate firmware update changed an optional field's availability. Its underlying reason is: Missing or changed raw fields propagate as null through report SQL unless a supported fallback is defined. This question instead describes a threat chart's numeric counts change after a parser update because the normalized severity field now stores values in a different scale. The original answer “Changing normalized severity representation alters grouping even when the number of raw detections has not changed” targets that failure because changing normalized severity representation alters grouping even when the number of raw detections has not changed.
The action “Archive-only historical data may not be immediately queryable by Analytics-backed report datasets” addresses a separate source case: A report job fails when an ADOM's Analytics retention is shorter than the requested reporting period but the administrator searches only archive files. Its underlying reason is: Archive-only historical data may not be immediately queryable by Analytics-backed report datasets. This question instead describes a threat chart's numeric counts change after a parser update because the normalized severity field now stores values in a different scale. The original answer “Changing normalized severity representation alters grouping even when the number of raw detections has not changed” targets that failure because changing normalized severity representation alters grouping even when the number of raw detections has not changed.
The action “Report charts depend on datasets within a specific ADOM context, not on identically named objects elsewhere” addresses a separate source case: A report was imported to another ADOM but a chart references a dataset name that does not exist there, producing an object-not-found error. Its underlying reason is: Report charts depend on datasets within a specific ADOM context, not on identically named objects elsewhere. This question instead describes a threat chart's numeric counts change after a parser update because the normalized severity field now stores values in a different scale. The original answer “Changing normalized severity representation alters grouping even when the number of raw detections has not changed” targets that failure because changing normalized severity representation alters grouping even when the number of raw detections has not changed.
