What is a subtype of the traffic log type?

In the context of Fortinet's FortiAnalyzer and its traffic logging capabilities, the correct answer identifies a subtype specifically relevant to traffic logs. The "Local" subtype is associated with traffic logs and refers to logs that are stored directly on the FortiGate unit rather than being forwarded to a centralized logging solution. This is significant because it separates in-context traffic data that is temporarily stored for quick access on the device itself.

Each of the other options represents different categories or types of logs within FortiAnalyzer but do not accurately depict a subtype of traffic logs. Application logs, for instance, capture data related to application usage patterns. System logs focus on the system-level events and statuses of the FortiGate device, while User logs record user-specific actions and access. By understanding these distinctions, a clearer picture emerges regarding the management and categorization of log data within FortiAnalyzer, emphasizing the unique role of "Local" as a subtype under traffic logs.
