Answers
D.
pdiff() and diff()
Suggested answer: A, B

Explanation:

When using a Python context manager with Junos PyEZ, two key methods are automatically included:

open() and close(): These methods are used to establish and terminate a connection to a Junos device. When you use a context manager (the with statement), open() is called when entering the block, and close() is called when exiting, ensuring the connection is properly managed.

lock() and unlock(): These methods are used to lock the configuration database to prevent other users from making changes while you are working on it. When using a context manager, lock() is called at the start of the block, and unlock() is called at the end, ensuring safe configuration changes.

Reference:

Junos PyEZ Documentation: The documentation explains how context managers work in PyEZ, including the automatic invocation of open(), close(), lock(), and unlock() methods.
