   A team is developing a Python application that uses a module named device_api.py. This module is imported by many other modules. The team wants to add a new feature to the module, but they are concerned about breaking existing functionality. They also want to allow other teams to use the module without modifying the original code. Which approach best addresses these concerns?

   • AUse a global configuration flag to enable the new feature in the original module.
   • BModify the original module to add the new feature, and update all importers to use the new version.
   • CCreate a new module that extends the original using inheritance or composition, and import the new module where needed.
   • DCopy the original module into a new file and modify the copy.

   A network automation engineer has written a Python module called device_utils.py that contains functions for device discovery and configuration. The engineer wants to reuse these functions in a new project without copying the code. What is the most appropriate way to achieve reuse?

   • ACopy the functions into the new project's main script.
   • BPackage the module into a library and install it in the new project using pip.
   • CRewrite the functions from scratch in the new project to ensure compatibility.
   • DUse a symlink to link the module file into the new project directory.

   Which statement best describes a primary benefit of using functions in a Python script for network automation?

   • AFunctions allow the script to run without an operating system.
   • BFunctions automatically encrypt all data transmitted by the script.
   • CFunctions eliminate the need for variables in the script.
   • DFunctions make the code more readable by giving a name to a block of logic.

   A developer is writing a Python script to manage network devices. The script needs to store device attributes (hostname, IP, credentials) and provide methods to connect, backup config, and reboot. Multiple devices will be handled, and the developer wants to ensure that each device's data is bundled with its operations. Which code organization best achieves this?

   • AUse a list of tuples for device data and a single function that handles all operations based on an index.
   • BDefine a class named NetworkDevice with attributes and methods, then create an instance for each device.
   • CStore device attributes in separate dictionaries and write standalone functions that accept a dictionary as an argument.
   • DCreate a module for each device and import the module when needed.
