Cisco Workload Optimization Manager provides specific real-time actions that ensure workloads get the resources they need when they need them, enabling continuous placement, resizing, and capacity decisions that can be automated, driving continuous health in the environment. You can automate the software's decisions according to your level of comfort: recommend (view only), manual (select and apply), or automated (executed in real time by software).

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.
