According to the FortiOS CLI Reference Guide, “The diagnose debug application foauthd command
enables debugging of certificate verification process in real time.” Therefore, option A is true
because it describes the CLI command that an administrator should use to view the certificate
verification process in real time. Option B is false because diagnose debug application radiusd -1
enables debugging of RADIUS authentication process, not certificate verification process. Option C is
false because diagnose debug application authd -1 enables debugging of authentication daemon
process, not certificate verification process. Option D is false because diagnose debug application
fnbamd -1 enables debugging of FSSO daemon process, not certificate verification process.
