Which two statements about the configuration synchronization feature on Cisco Nexus switches are true? (Choose two.)
The correct answer is A. Config-sync mode allows you to create a switch profile that can be used to configure a peer switch E. Configuration synchronization uses the Cisco Fabric Services over IP protocol. Cisco Nexus switch configuration synchronization allows creating a switch profile to configure a peer switch and uses the Cisco Fabric Services over IP (CFSoIP) protocol for communication.

Why each option
Cisco Nexus switch configuration synchronization allows creating a switch profile to configure a peer switch and uses the Cisco Fabric Services over IP (CFSoIP) protocol for communication.
Config-sync mode on Cisco Nexus switches enables the creation of a switch profile, which can then be applied to synchronize configurations across peer switches, particularly in a vPC domain.
While configuration synchronization is useful for vPC, it does not synchronize all parts of the vPC configuration; some elements, like interface-specific configurations, must still be done manually or using other tools.
Configuration synchronization uses Cisco Fabric Services over IP (CFSoIP), not Cisco Fabric Services over IPv6 (CFSoIPv6).
FEX interfaces are compatible with configuration synchronization, as FEX configurations are often synchronized between vPC peer switches.
Configuration synchronization between Cisco Nexus switches relies on the Cisco Fabric Services over IP (CFSoIP) protocol to reliably transfer configuration data.
