Which NTP mode must be activated when using a Cisco router as an NTP authoritative server?
When configuring a Cisco router as an NTP authoritative server, the router must be set in 'server' mode. This mode allows the router to provide time synchronization information to other devices on the network, acting as a time source. The 'server' mode is appropriate since it designates the router as an authoritative source of time that other devices can synchronize with.
That is just fantastic... The Q is about the mode, not a command. So, server is the mode while you need to use master command to enable it hence the answer is D.
Totally Agree!! Cisco just wants to confuse us with words, we need to pay attention to the question.
I think these types of questions are planted in there just to mess with test takers. "Master" is when you want a Cisco router to act as an authoritative NTP server. "Server <ip-address-of-authoritative-server>" is when you want a Cisco router to act as an NTP client and sync from an authoritative NTP server.
System as an Authoritative NTP Server: Use the ntp master command in global configuration mode if you want the system to be an authoritative NTP server, even if the system is not synchronized to an outside time source. https://www.cisco.com/c/dam/en/us/td/docs/ios-xml/ios/bsm/configuration/xe-3se/3650/bsm-xe-3se-3650-book.html#:~:text=ntp%20server%20command.-,System%20as%20an%20Authoritative%20NTP%20Server,to%20an%20outside%20time%20source.&text=Use%20the%20ntp%20master%20command%20with%20caution.
agree. and if we don't have master as an option, i would say peer?
Wrong dump if you ask me.
When using a Cisco router as an NTP (Network Time Protocol) authoritative server, you typically want to configure it in NTP Server mode. In NTP terminology, this is referred to as the "NTP Server" mode. In this mode, the Cisco router will provide time synchronization information to other devices in your network, acting as a time source for them. Other devices can then synchronize their clocks with the Cisco router's clock. To configure a Cisco router as an NTP server, you would use commands like: shell: ntp server <server-ip-address>
Server mode.
Server mode
D is correct
Is D for me.. Regards
My logic says D is correct. If it's an authoritative server, it should be a server. "Peer" means the NTP server is getting its time from someone else and passing it along to clients (correct me if I'm wrong). If that's the case, it's not an "authoritative" time source, it's just passing the data along from a more authoritative source.
ntp server is the command that points it to a server. NTP master or NTP peer is for creating authoritative NTP server.
