A network administrator is troubleshooting a network issue in a multi$-$interface device that operates both an Ethernet and a Wi$-$Fi connection.

The administrator discovers that despite both interfaces having a valid IPv$6$ link local address, there seems to be confusion about where packets should be

routed for local network operations.

What should the administrator check to resolve this issue?

The global unicast addresses of the interfaces

The subnet masks of the interfaces

The encryption settings of the interfaces

The zone indices appended to the link local addresses
