these are different steps in the process of configuring a network device
1) PnP is for out-of-the box/initial configuration, so that the switch gets a basic/default configuration
so it can be managed remotely and cooperate with your other network equipment
this involves software distribution and configuration using a template with commands
this template is called called day-zero template
2) provisioning is a next step to modify the configuration as needed for a specific purpose
some configuration here could also be included in the day-zero template ,
but there can be advantages to do some commands using day-N templates
you need a design how to divide configuration commands between day-zero and day-n templates
e.g. you have a basic template for ALL switches, and an extra day-n template for site-A (but not for site-B)
3) LAN automation is very broad subject,
in short it is automatically reconfiguring your network when a specific trigger occurs
(really configuration change, not only redundant routes or so)
=> if THIS happens, how do I reconfigure the network to route traffic as I want it (without manual intervention)
