Answer is C. App-ID is paloalto-gp-mfa-notification. MultiFactor Authentication gateway (firewall) sends an UDP notification message to GlobalProtect client, when the client accesses a non-browser (such as SSH) based resource, to notify the client/end-user to authenticate first before accessing the resource.
