Question
An engineer is adding a Cisco router to an existing environment. NTP authentication is configured on all devices in the environment with the command ntp authentication-key 1 md5 Cisc433392759. There are two routers on the network that are configured as NTP servers for redundancy, 192.168.1.110 and 192.168.1.111. 192.168.1.110 is configured as the authoritative time source. What command must be configured on the new router to use 192.168.1.110 as its primary time source without the new router attempting to offer time to existing devices?
Options
- Antp server 192.168.1.110 primary key 1
- Bntp server 192.168.1.110 key 1 prefer
- Cntp peer 192.168.1.110 prefer key 1
- Dntp peer 192.168.1.110 key 1 primary
Explanation
To configure the new router to use 192.168.1.110 as its preferred NTP time source with authentication, without becoming an NTP server itself, the ntp server command with the key and prefer options is required.
Common mistakes.
- A. The
primarykeyword is not a valid option for thentp servercommand to designate a preferred server; the correct keyword isprefer. - C. The
ntp peercommand configures the device to both send and receive NTP packets, meaning it could potentially offer time to other devices, which contradicts the requirement of not offering time. - D. The
ntp peercommand would allow the new router to offer time, andprimaryis not the correct keyword for preferring a server,preferis.
