   A company is deploying a Python script that uses the Cisco DNA Center SDK to automate network changes. The script must authenticate using a service account with a password that rotates every 30 days. The security team requires that the password never be stored in plain text in the script or in environment variables. Which approach best meets these requirements?

   • AHardcode the password in the script and update it manually every 30 days.
   • BUse an environment variable that is set in the CI/CD pipeline.
   • CStore the password in a secure vault and retrieve it at runtime using the vault's API.
   • DUse the SDK's built-in token caching to avoid needing the password after the first authentication.

   A developer is setting up a Python environment to use the Webex SDK. The developer has already installed the webexteamssdk package. When running a script that imports the SDK, the developer gets a ModuleNotFoundError. What is the most likely cause?

   • AThe SDK requires Python 3.9 or later, and the developer is using an older version.
   • BThe script is running in a different Python environment than the one where the SDK was installed.
   • CThe SDK must be installed with sudo.
   • DThe import statement is incorrect; it should be 'import webex' instead of 'from webexteamssdk import WebexAPI'.

   An engineer is using the Cisco DNA Center SDK to retrieve a list of network devices and then update the SNMP community string on each device. The engineer notices that the script takes a long time because it makes sequential API calls. The engineer wants to improve performance without compromising reliability. Which approach is best?

   • AUse asyncio to make all calls concurrently without any limits.
   • BMake the calls sequentially but reduce the timeout to speed up each call.
   • CUse the SDK's built-in batch update feature.
   • DUse Python's concurrent.futures.ThreadPoolExecutor to parallelize the update calls, but keep the number of workers low to avoid rate limits.
