Question 50
A FortiAnalyzer administration handover records the following: The SOC needs to know whether a rise in log volume comes from a newly onboarded branch, but analysts only check total disk percentage. Which statement describes the decisive system dependency?
Explanation
Correct Answer
Log receive statistics expose the rate and origin of ingestion, whereas total storage usage alone cannot identify which sender changed. This behavior determines the engineering decision. The appropriate action is: Use FortiAnalyzer log receive monitoring to compare per-device arrival rates and volumes over the incident interval. Verify success by checking: The branch serial appears as the source of the ingestion spike and the per-device rate aligns with the firewall logging policy.
Incorrect Answers
The action “Device serial alone may not identify a VDOM-specific policy context; source and virtual domain metadata affect analysis” addresses a separate source case: A FortiGate with multiple VDOMs sends messages, but an analyst cannot distinguish which tenant produced a particular security event. Its underlying reason is: Device serial alone may not identify a VDOM-specific policy context; source and virtual domain metadata affect analysis. This question instead describes the SOC needs to know whether a rise in log volume comes from a newly onboarded branch, but analysts only check total disk percentage. The original answer “Log receive statistics expose the rate and origin of ingestion, whereas total storage usage alone cannot identify which sender changed” targets that failure because log receive statistics expose the rate and origin of ingestion, whereas total storage usage alone cannot identify which sender changed.
The action “ADOMs provide separate administrative contexts for managed devices and log analysis, so assignment affects which data and resources analysts see” addresses a separate source case: Three subsidiaries share one FortiAnalyzer but analysts accidentally see each other's logs because every firewall was assigned to one common administrative domain. Its underlying reason is: ADOMs provide separate administrative contexts for managed devices and log analysis, so assignment affects which data and resources analysts see. This question instead describes the SOC needs to know whether a rise in log volume comes from a newly onboarded branch, but analysts only check total disk percentage. The original answer “Log receive statistics expose the rate and origin of ingestion, whereas total storage usage alone cannot identify which sender changed” targets that failure because log receive statistics expose the rate and origin of ingestion, whereas total storage usage alone cannot identify which sender changed.
The action “A reachable IP path does not guarantee establishment of the authenticated or encrypted forwarding transport” addresses a separate source case: A backup SOC collector is reachable by ICMP, yet secure log forwarding fails with a certificate or negotiated-channel error. Its underlying reason is: A reachable IP path does not guarantee establishment of the authenticated or encrypted forwarding transport. This question instead describes the SOC needs to know whether a rise in log volume comes from a newly onboarded branch, but analysts only check total disk percentage. The original answer “Log receive statistics expose the rate and origin of ingestion, whereas total storage usage alone cannot identify which sender changed” targets that failure because log receive statistics expose the rate and origin of ingestion, whereas total storage usage alone cannot identify which sender changed.
