Explanation / Answer

Network operations starts with monitoring,Monitoring provides the visibility that facilitates all other operational tasks.Network management is often conflated with monitoring but they are really entirely two separate things.Monitoring observes the current state of the network and helps you to detect , predict and prevent problems .Management means controlling device configuration and firmware versions.Ausit trails are regulatory requirements for many business and extremely useful for all business .The lifecycle phases for a network are in stock,assigned ,installed,deploying ,operational servicing,and disposed .

Configuration management for network devices lags behind what is being done with work stations and severs .

Hope this will help
