What are three Junos automation scripts?

(A,C,D)

Junos automation is a powerful suite of tools for automating the
methods and procedures of operating a network. Automation can not
only save your team time, it also helps to establish high performance
operation of the network and to manage greater scale in the network
by simplifying complex tasks.
The tool sets let you automate a majority of the commands used
within the Junos command-line, further control the commit process,
as well as automate the response to defined events. Junos includes
three types of automation scripts, each providing different types of
functionality for automation:
n Operation (op) scripts instruct Junos of actions to take whenever
the script is called through the command-line or by another script.
n Event scripts instruct Junos of actions to take in response to an
occurrence in a monitored set of events.
n Commit scripts instruct Junos of actions to take during the
commit process of activating configuration changes.
