Exam NSE5_FSW_AD-7.6 Topic 1 Question 25 Discussion

When a FortiSwitch is converted fromstandalone (local) management modetoFortiGate-managed mode using FortiLink, FortiSwitchOS follows a well-defined and protective transition process. According to the FortiSwitchOS 7.6 Administrator Guide, the switchdoes not mergeits existing standalone configuration with FortiLink-managed settings, nor does FortiGate import or preserve the active configuration for reuse.
Instead, when the management mode change occurs, the FortiSwitchsaves the current standalone configuration internallyand thenresets its operational configuration to the default FortiLink configuration. This default configuration is required so the switch can correctly establish FortiLink control- plane communication with the FortiGate, including CAPWAP-based management, VLAN 4094 usage, and dynamic policy provisioning.
Once the FortiSwitch is under FortiGate management,all configuration is controlled centrally by the FortiGate, including VLANs, port policies, security features, and firmware management. The previously saved standalone configuration is retained only as a backup reference on the switch and isnot actively used unless the switch is later reverted back to standalone mode.
This behavior ensures configuration consistency, prevents conflicts between local and centralized policies, and aligns the switch with the FortiGate-centricSecurity Fabric architecture. It also avoids unpredictable results that could occur if legacy standalone settings were merged with FortiLink-managed profiles.
The other options are incorrect because FortiSwitch does not register with FortiSwitch Cloud automatically, does not merge configurations, and FortiGate does not back up the standalone configuration during onboarding.
Therefore, the correct and fully documented answer isC. FortiSwitch saves the standalone configuration and changes to the default FortiLink configuration.
