Which two statements regarding FortiAnalyzer operating modes are true?

Exact Extract: Study Guide p.22-p.24: analyzer is the default mode; collector mode forwards logs, including to syslog/CEF, and mixed deployments improve scale.

Technical Deep Dive: The correct answers are A and D. In collector mode, FortiAnalyzer collects logs and forwards them to another analyzer, syslog server, or CEF server depending on forwarding mode. A topology using both collectors and analyzers can improve performance and regional scalability by offloading collection and keeping analysis/reporting on analyzer devices. Option B is wrong because analyzer mode is the default, not collector mode. Option C is wrong because collector mode has fewer features and does not provide reporting or event-management capabilities.
