ExplanationSNMP polling can often be in the order of 5-10 minutes, CLIs are unstructured and prone to change which can often break scripts.The traditional use of the pull model, where the client requests data from the network does not scale when what you want is near real-time data.Moreover, in some use cases, there is the need to be notified only when some data changes, like interfaces status, protocol neighbors change etc.Model-Driven Telemetry is a new approach for network monitoring in which data is streamed from network devices continuously using a push model and provides near real-time access to operational statistics.

Explanation
To configure an NTP enabled router to require authentication when other devices connect to it, use the following commands:
NTP_Server(config)#ntp authentication-key 2 md5 securitytut
NTP_Server(config)#ntp authenticate
NTP_Server(config)#ntp trusted-key 2
Then you must configure the same authentication-key on the client router:
NTP_Client(config)#ntp authentication-key 2 md5 securitytut
NTP_Client(config)#ntp authenticate
NTP_Client(config)#ntp trusted-key 2
NTP_Client(config)#ntp server 10.10.10.1 key 2
Note: To configure a Cisco device as a NTP client, use the command ntp server <IP address>. For example:
Router(config)#ntp server 10.10.10.1. This command will instruct the router to query 10.10.10.1 for the time.
