Correct answer is D.
When a boot NTP server is configured, the Junos system will only sync against it during the boot process. After the boot process finishes the Junos system will never sync against it. That is why configuring a boot NTP server is not a best practice.
The Junos will sync against a NTP server just if it was defined as an ntp server (‘set system ntp server )
C
I think c also
if 172.25.11.254 is a real ntp server address, answer D is correct because the confirguration from exhibit is under [edit system ntp]
root> set date ntp ?

{master:0}
{master:0}[edit]
root# edit system ntp
{master:0}[edit system ntp]
root# set server ?
Possible completions:
Name or address of server
{master:0}[edit system ntp]
how about option C ???
the console shows # with configure mode rather than > operational mode
option C is the correct one
