The correct command to configure the switch as an authoritative NTP server is A. switch(config)#ntp master 3.
Here is a detailed explanation of the command and the other options:
A. switch(config)#ntp master 3 - This command configures the switch as an NTP server and sets the stratum value to 3, indicating that it is an authoritative time source.
B. switch(config)#ntp server 193.168.2.2 - This command configures the switch to synchronize its time with the specified NTP server at the IP address 193.168.2.2. This command does not configure the switch as an authoritative NTP server.
C. switch(config)#ntp peer 193.168.2.2 - This command configures the switch to synchronize its time with the specified NTP peer at the IP address 193.168.2.2. This command does not configure the switch as an authoritative NTP server.
D. switch(config)#ntp source 193.168.2.2 - This command specifies the source IP address that the switch should use when sending NTP packets. It does not configure the switch as an authoritative NTP server.
In summary, the correct command to configure the switch as an authoritative NTP server is "ntp master". The other options either configure the switch to synchronize its time with another NTP server or peer or specify the source IP address for NTP packets.
