Question 370
A FortiAnalyzer 7.6 SOC analyst investigates this deployment: After a logging outage, FortiView reports a sudden reduction in sessions and managers call it successful traffic reduction. Which statement describes the decisive system dependency?
Explanation
Correct Answer
An ingestion gap can make traffic summaries fall even if actual network activity remains constant. This behavior determines the engineering decision. The appropriate action is: Compare the FortiView period with log ingestion and source availability before interpreting session changes. Verify success by checking: The timeline marks the missing data and an independent traffic source confirms the true activity level.
Incorrect Answers
The action “Time filtering changes which log samples contribute to an aggregate, so rankings can differ by investigation interval” addresses a separate source case: A threat dashboard ranks one destination highly, but an analyst needs to isolate whether the spike occurred in the previous hour or over the whole week. Its underlying reason is: Time filtering changes which log samples contribute to an aggregate, so rankings can differ by investigation interval. This question instead describes after a logging outage, FortiView reports a sudden reduction in sessions and managers call it successful traffic reduction. The original answer “An ingestion gap can make traffic summaries fall even if actual network activity remains constant” targets that failure because an ingestion gap can make traffic summaries fall even if actual network activity remains constant.
The action “Policy-focused aggregation reveals which rules handle observed sessions and bytes” addresses a separate source case: A firewall change is suspected of increasing traffic through policy 41, and the team wants policy-specific evidence rather than a network-wide bandwidth total. Its underlying reason is: Policy-focused aggregation reveals which rules handle observed sessions and bytes. This question instead describes after a logging outage, FortiView reports a sudden reduction in sessions and managers call it successful traffic reduction. The original answer “An ingestion gap can make traffic summaries fall even if actual network activity remains constant” targets that failure because an ingestion gap can make traffic summaries fall even if actual network activity remains constant.
The action “Threat-destination views aggregate the targets of security events, differing from signature-frequency charts” addresses a separate source case: An analyst sees many threat alerts but needs to know the most frequently targeted servers rather than which detection signatures are globally common. Its underlying reason is: Threat-destination views aggregate the targets of security events, differing from signature-frequency charts. This question instead describes after a logging outage, FortiView reports a sudden reduction in sessions and managers call it successful traffic reduction. The original answer “An ingestion gap can make traffic summaries fall even if actual network activity remains constant” targets that failure because an ingestion gap can make traffic summaries fall even if actual network activity remains constant.
