Understanding the FortiAnalyzer Fabric:

The FortiAnalyzer Fabric provides centralized log collection, analysis, and reporting for connected FortiGate devices.

Devices in a FortiAnalyzer Fabric can be organized into different Administrative Domains (ADOMs) to separate logs and management.

Analyzing the Exhibit:

FAZ-SiteAandFAZ-SiteBare FortiAnalyzer devices in the fabric.

FortiGate-B1andFortiGate-B2are shown under theSite-B-Fabric, indicating they are part of the same Security Fabric.

FAZ-SiteAhas multiple entries under it:SiteAandMSSP-Local, suggesting multiple ADOMs are enabled.

Evaluating the Options:

Option A:FortiGate-B1 and FortiGate-B2 are underSite-B-Fabric, indicating they are indeed part of the same Security Fabric.

Option B:The presence of FAZ-SiteA and FAZ-SiteB as FortiAnalyzers does not preclude the existence of collectors. However, there is no explicit mention of a separate collector role in the exhibit.

Option C:Not all FortiGate devices are directly registered to the supervisor. The exhibit shows hierarchical organization under different sites and ADOMs.

Option D:The multiple entries underFAZ-SiteA(SiteA and MSSP-Local) indicate that FAZ-SiteA has two ADOMs enabled.

Conclusion:

FortiGate-B1 and FortiGate-B2 are in a Security Fabric.

FAZ-SiteA has two ADOMs enabled.
